No this is not to use steam for another stroke.</div><div><br /></div><div>In this idea separate hydrogen and oxygen using a small battery and feed both also with the petrol to the engine. This enhances the firing and produces more output. so less gas is only required to have the same output.

Holy hell! This car could not have been more instantly hated if it had a Swastika tattoo on its forehead. In later interviews with GM designers — who, for decency's sake, will remain unnamed — it emerged that the <span class="blsp-spelling-error" id="SPELLING_ERROR_1">Aztek</span> design had been fiddled with, fussed over, cost-shaved and otherwise compromised until the tough, cool-looking concept had been reduced to a bulky, plastic-clad mess. A classic case of losing the plot. The <span class="blsp-spelling-error" id="SPELLING_ERROR_2">Aztek</span> violates one of the principal rules of car design: We like cars that look like us. With its multiple eyes and supernumerary nostrils, the <span class="blsp-spelling-error" id="SPELLING_ERROR_3">Aztek</span> looks deformed and scary, something that dogs bark at and cathedrals employ to ring bells (cf., Fiat <span class="blsp-spelling-error" id="SPELLING_ERROR_4">Multipla</span>).

So we need an approach which is hybrid but more upgradable to future. As the Fuel cell and <span class="blsp-spelling-error" id="SPELLING_ERROR_1">EVs</span> depends on the electricity the approach needed to be electricity centric. </div><div><br /></div><div>One approach is a serial hybrid. There are other approaches like parallel hybrids, mild hybrids, strong hybrids, BAS hybrids etc. The good part of  serial hybrid is that its more future oriented and its a step closer to the renewable non fossil vehicles.</div><div><br /></div><div>This post is an extension of the previous post of "something before volt".  This post is reflections of my thoughts on a 10 mile capable battery <span class="blsp-spelling-error" id="SPELLING_ERROR_2">EREV</span>. Because its for a 10 mile range, we assume the battery costs are less. We even  think it can be a ultra capacitor also because we need a device which can store and provide energy for the vehicle to travel 10 miles electrically.</div><div><br /></div><div><br /></div><div>The first step is a test EV ( electric vehicle ) which as capability to record the power used by the electric engine on a defined cycle. A cycle is a defined patten of driving for a particular time period. </div><div><br /></div><div>The Test  Ev will have the exact motor configuration we plan to have in our final product.</div><div>Example One motor 2 rear wheels ( say 90kw) and 2 in wheel motors ( 30kw ) for the 2 front wheels.</div><div><br /></div><div>This configuration gives the advantages of rear wheel drive and on required conditions the front wheels can act and get <span class="blsp-spelling-error" id="SPELLING_ERROR_3">AWD</span> advantages. Secondly the front motors will  be more concentrating on regeneration of power from the regenerative breaking.</div><div><br /></div><div><br /></div><div>As a detailed step we will go through the different cycles defined by different standard authorities for the emission tests.</div><div><br /></div><div>look at http://www.dieselnet.com/standards/cycles/ and get the required information , contact the  authorities and get the documents.</div><div><br /></div><div>Some interesting cycles for US  are </div><div><br /></div><div><ol><li> US06  : 600 seconds long  representation of aggressive, high speed and/or high acceleration driving behavior, rapid speed fluctuations, and driving behavior following start up.  http://www.dieselnet.com/standards/cycles/ftp_us06.html</li><li> FTP 75 : http://www.dieselnet.com/standards/cycles/ftp75.html<br /></li><li><span class="blsp-spelling-error" id="SPELLING_ERROR_4">HWFET</span> cycle : http://www.dieselnet.com/standards/cycles/hwfet.html<br /></li><li>New york city cycle : http://www.dieselnet.com/standards/cycles/nycc.html<br /></li><li> California Unified Cycle (<span class="blsp-spelling-error" id="SPELLING_ERROR_5">UC</span>) : http://www.dieselnet.com/standards/cycles/uc.html<br /></li><li>The SC03 Supplemental Federal Test Procedure : http://www.dieselnet.com/standards/cycles/ftp_sc03.html<br /></li></ol></div><div><br /></div><div>etc etc. for a primary study on different cycles use : <a href="http://www.dieselnet.com/standards/cycles/">http://www.dieselnet.com/standards/cycles/</a></div><div><br /></div><div>Similarly use all the countries you are interested in and get the cycle information. </div><div><br /></div><div>Now perform these cycles with the test EV and get all data points and plot graph on the power requirements against time , Now you have two graphs where one with speed vs time and second energy requirements vs time. </div><div><br /></div><div>Repeat the procedure with the cycles you have interest and make the data ready.</div><div><br /></div><div>Now its time to choose a optimal electric generator with </div><div><span class="Apple-tab-span" style="white-space:pre"> </span>1) Emission characteristics matching the cycle requirement.</div><div>        2) Electricity generation capability which is at an optimal level for the above data collected cycles. Assume battery will be supplementing the extra power needs.</div><div><br /></div><div>The modes the range extender will operate are :</div><div><br /></div><div><br /></div><div><ul><li>PURE EV mode<br /></li><li>Generator power only mode<br /></li><li>Generator power + Battery power mode<br /></li><li>Battery recharge mode<br /></li><li>Generator power only run   and Battery recharge mode<br /></li></ul></div><div><br /></div><div>Regeneration can occur on all the above mode as user uses the breaks and other regenerative mechanisms ( example: regenerative shock absorbers )</div><div><br /></div><div><br /></div><div><br /></div><div>So as per the logic : The range extender will run on EV mode when the battery is full and above threshold range extender point. Lets say if its  10 mile battery 5 miles in EV mode</div><div>Once it reaches 5 miles, the generator kicks in and acts as primary source of running, Now the battery will act as a supplemental energy provider on acceleration, load and uphill ( more </div><div>energy need scenarios ). The battery will be charged back when ever there is an opportunity for regeneration of the power. The generator will recharge the battery when the vehicle is </div><div>in a stop position or need less power than the optimal point power which generator is deigned to generate.Once the power inside the battery reaches back to a level say "return EV mode point"</div><div>say 7 mile capability, the generator will be shut off back and the Range extender will run in a Pure EV mode. again when it hits back the threshold range extender point the generator will be kicking in again back.</div><div><br /></div><div><br /></div><div>The points </div><div> 1) the constant generator capacity,</div><div> 2) Threshold range extender point</div><div> 3) Return EV mode point </div><div><br /></div><div>etc should be designed by the applications processing unit intelligence. This can be visualized as profiles ( example: city profile, High way profile, Up hill profile, <span class="blsp-spelling-error" id="SPELLING_ERROR_6">AWD</span> profile ,Intelligent <span class="blsp-spelling-error" id="SPELLING_ERROR_7">AWD</span> profile , etc will have different values for the points and will result in different drive experiences for the users). By adding <span class="blsp-spelling-corrected" id="SPELLING_ERROR_8">plug in</span> charging , the vehicle should be able to work as a <span class="blsp-spelling-corrected" id="SPELLING_ERROR_9">plug in</span> hybrid.</div><div><br /></div><div><br /></div><div>Once, the design of profiles are also completed, we will be almost ready will the design and only new places to explore may be the traction control mechanisms only. Once completing the data points and logic of control, we will be ready to develop the software needed and make out <span class="blsp-spelling-error" id="SPELLING_ERROR_10">EREVs</span> first tests. The data points can be perfected using software using proving grounds, test fleets </div><div>etc and they can be always updated with software/firmware downloads.</div><div><br /></div><div>Yes guys, We now did a design of a global focused designed <span class="blsp-spelling-error" id="SPELLING_ERROR_11">EREV</span>.

Lets think of a below configuration</div><div><br /></div><div>                  +--------------------------  Control  circuit</div><div>                  |                                                       |</div><div>Electric generator ------ Ultra capacitor----Electric Motor </div><div><br /></div><div>Why this is cost effective ?Genarator powers the electric motor,  The ultra capacitor stores the energy from the generator  some times ( like down hill, stops etc ) and other times it stores the regenerative energy . The electric motor takes electric energy from the ultra capacitor when it needs execss energy like up hill etc. This will be very cost effective as Ultra capacitr is not expensive as battery and range requiremnt is only 10 - 15 mile ( or even 5 mile )</div><div><br /></div><div>If the Ultra capacitor can store energy for X miles AER, the Electric generator can always run in optimum capacity and be shut off till  the ultra capacitor reaches to be in a depletion area (say x-n ). Once its in depeltion area . the generator can charge and store more energy in it and support the power needs of the car by supplying additionl energy for uphill, merge etc. </div><div><br /></div><div><br /></div><div>The down side : It wont perform on uphills like normal drive it the hill is very big/steep (after ultacapacitir runs out of energy ). </div><div><br /></div><div> But comparing to the cost it should be a good step to consider before the volt and it will have less weight compared to BEVs and gives the cost effective first step on full electric drive.

Lets first explain a four stroke engine </div><div><br /></div><div><span class="Apple-style-span" style="font-weight: bold;">Four stoke engine</span> consists of </div><div>  Intake stroke</div><div>  Compression stroke</div><div>  Power stroke</div><div>  Exhaust stroke</div><div><br /></div><div>In intake stroke, the air is taking in then compress the air ,fuel gets injected to the compressed air and then ignited results in the power stroke and after the compression stroke the exhaust gases will be removed in the exhaust stroke. Its all fine and give 35-37% efficiency.</div><div><br /></div><div>One of the problem is the heat is never utilized for any purpose.  So the idea of six stroke engine came in.</div><div> </div><div>The <span class="Apple-style-span" style="font-weight: bold;">six-stroke engine</span> is a type of internal combustion engine based on the four-stroke engine, but with additional complexity to make it more efficient and reduce emissions. </div><div><br /></div><div>Two different types of six-stroke engine have been developed since the 1990s:</div><div><br /></div><div>In the first approach, the engine captures the heat lost from the four-stroke Otto cycle or Diesel cycle and uses it to power an additional power and exhaust stroke of the piston in the same cylinder. Designs use either steam or air as the working fluid for the additional power stroke. As well as extracting power, the additional  stroke cools the engine and removes the need for a cooling system, making the engine lighter and giving an estimated efficiency of 40%. The pistons in this type of six-stroke engine go up and down six times for each injection of fuel.</div><div><br /></div><div> There are two power strokes: one with fuel, the other with steam or air.</div><div><br /></div><div>The second approach to the six-stroke engine uses a second opposed piston in each cylinder that moves at half the cyclical rate of the  main piston, thus giving six piston movements per cycle. Functionally, the second piston replaces the valve mechanism of a conventional  engine but also increases the compression ratio. </div><div><br /></div><div><br /></div><div>I started thinking more in this direction and found another way called <span class="Apple-style-span" style="font-weight: bold;">NP Stroke engine</span> and <span class="Apple-style-span" style="font-weight: bold;">Active Stroke cycle management</span> for a better solution.. </div><div><br /></div><div>The theory i propose always gives variable  efficiency optimal according the  circumstance of operation.  </div><div><br /></div><div>Lets go to the first proposal of NP  stroke engine. </div><div><br /></div><div>N is a number where this can be 1 to any number. P denotes Power stroke, Lets explain how NP stroke engine works when N is equal to 3.</div><div><br /></div><div>The additional requirements/changes in the design is an additional  closed hot air chamber, Air injector , Heat transfer agent and injector ( ex water).</div><div><br /></div><div>Once the 4 strokes of 4 stroke engine is over , the exhaust stroke will push the air to the air chamber. Once the exhaust stroke is over, instead of another intake stroke,  1/3rd of the hot exhaust air stored in the air chamber is released to the intake .After this a  compression stroke of this air occurs. Once its compressed, a heat transfer agent is injected (ex: water ). This agent will utilize the heat in the exhaust gas and convert to a vapour form results in a power stroke. Once the power stroke is over another exhaust stroke occurs and the exhaust is send out. Again in another intake stroke the air injector injects another 1/3 of the exhaust gas and same 4 strokes occurs. Lets call these strokes as thermal energy transfer strokes. Once the 4 strokes are over, the last 1/3 is utilized t make another 4 strokes. which results in total of 12 strokes.</div><div><br /></div><div>Which means the engine gets 3 times efficient than the normal 4 stroke engine. </div><div><br /></div><div>Here a number of  questions arises : </div><div><br /></div><div>Is 3 an optimal number ? </div><div>What happens in a cold place</div><div>What happens when i drive a lot</div><div>What happens when i start the car where engine is cool.</div><div><br /></div><div>Here the second theory comes in effect.

Conventional braking systems use friction to counteract the forward momentum of a moving car. As the brake pads rub against the wheels (or a disc connected to the axle), excessive heat energy is also created. This heat energy dissipates into the air, wasting up to 30% of the car's generated power. Over time, this cycle of friction and wasted heat energy reduces the car's fuel efficiency. More energy from the engine is required to replace the energy lost by braking.</div><div><br /></div><div>Regenerative braking utilizes the fact that an electric motor can also act as a generator. The vehicle's electric traction motor is operated as a generator during braking and its output is supplied to an electrical load. It is the transfer of energy to the load which provides the braking effect.</div><div><br /></div><div>As the driver applies the brakes through a conventional pedal, the electric motors reverse direction. The torque created by this reversal counteracts the forward momentum and eventually stops the car.</div><div><br /></div><div>At the most basic level, regenerative braking means re-capturing the kinetic energy of the vehicle's motion and turning it into another type of energy. Commonly, this is done by converting kinetic energy into electricity and recharging the car's battery with it.The energy captured in the battery is used moving the car later and due to the energy capture and reutilization the mpg for the car improves drastically.</div><div><br /></div></div><div><br /></div>© yankandpaste®<div class="blogger-post-footer">© yankandpaste®.blogspot.com<img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8576780862978816982-5071086255601426294?l=yankandpaste.blogspot.com'/></div>Unnihttp://www.blogger.com/profile/11647147116239881353noreply@blogger.com0tag:blogger.com,1999:blog-8576780862978816982.post-46981746278006951952009-05-02T10:06:00.001-07:002009-05-02T10:12:48.761-07:00What is cD and why does it matter?<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://upload.wikimedia.org/wikipedia/commons/8/8a/Aptera-2e-render-1.jpg"><img style="cursor:pointer; cursor:hand;width: 758px; height: 386px;" src="http://upload.wikimedia.org/wikipedia/commons/8/8a/Aptera-2e-render-1.jpg" border="0" alt="" /></a><br /><div><br /></div><div><br /></div><div><div>Aerodynamics. When discussing overall efficiency, sometimes it's easy to overlook just how important the shape of an automobile is in determining how fuel efficient it is</div><div><br /></div><div>First, let's discuss what the term aerodynamics means. According to Merriam-Webster, aerodynamics is "a branch of dynamics that deals with the motion of air and other gaseous fluids and with the forces acting on bodies in motion relative to such fluids." Clear as mud? In this case, the fluid we're talking about is indeed air, and the easier it is for an object to cut through the air, the less energy is required to keep that body in motion.</div><div><br /></div><div><br /></div><div><br /></div><div>For the purpose of comparing different automotive designs, engineers measure the resistance of a body to flow through the air using computational fluid dynamics simulations and wind tunnel testing. A flat board held perpendicular to the air flow may have a coefficient of 1 or more, depending on the shape of the edges and the surface texture. The drag coefficient is a unitless number and is based on the shape and surface properties of the object. Two identical objects that are different sizes will have the same cD. However, that doesn't mean they have the same overall drag. </div><div><br /></div><div>This, of course, is further complicated by the vagaries of the real world. The addition of items like outside mirrors, windshield wipers and radio antennas can cause a lot of disruption to air-flow. There is also the fact that cars often don't travel perpendicular to air-flow. Vehicles often encounter cross-winds when driving down the road so the airflow must be measured at various angles to ensure resistance is kept to a minimum. </div><div><br /></div><div>Safety is also a concern.The air-flow over a vehicle's body can trigger either lift or down-force just as it does with an aircraft wing. If a vehicle's shape causes too much lift, it can make the vehicle unstable and difficult to control. All of these factors must be balanced in the final design.</div><div><br /></div></div><div><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://upload.wikimedia.org/wikipedia/commons/3/37/14ilf1l.svg"><img src="http://upload.wikimedia.org/wikipedia/commons/3/37/14ilf1l.svg" border="0" alt="" style="float: right; margin-top: 0px; margin-right: 0px; margin-bottom: 10px; margin-left: 10px; cursor: pointer; width: 200px; height: 381px; " /></a>The designers of all of the most fuel efficient vehicles ever offered for sale have taken aerodynamics very seriously and as such, they all have a very favorable cD. For instance, the GM EV1 scored a cD of 0.195, which is quite good. For comparison, the 2010 Toyota Prius manages a fine 0.25 and the Aptera 2e (above) blows them both out of the water air with an amazingly low 0.15. When multiplied by the car's frontal area, the Aptera design scores even better due to its narrow, bullet-like shape with narrow out-rigger front wheels that are completely shrouded . For what it's worth, the brick-shaped HUMMER H2 scores a dismal 0.57 – further proof that its designers were in no way concerned with its fuel efficiency.</div><div><br /></div><div>Besides the actual bodywork of an automobile, there are other factors contributing to the overall coefficient of drag any given car is able to register, including the car's tires and its ride height. Wide tires move more air and therefore take more power to move, and the air pressure of a given tire can have drastic consequences on its ability to roll. </div><div><br /></div><div>Why is all of this so important? Calculations reveal that about 60 percent of the energy used to move the average car goes towards overcoming its aerodynamic drag. That's huge, and means that even small improvements in a car's cD can pay big dividends in overall fuel efficiency. </div><div class="blogger-post-footer">© yankandpaste®.blogspot.com<img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8576780862978816982-4698174627800695195?l=yankandpaste.blogspot.com'/></div>Unnihttp://www.blogger.com/profile/11647147116239881353noreply@blogger.com0tag:blogger.com,1999:blog-8576780862978816982.post-91224558028644096422009-04-30T22:41:00.000-07:002009-05-03T15:26:06.294-07:002 mode power train :Speed to time graph and modes.<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://www.blogcdn.com/www.autobloggreen.com/media/2008/01/two-mode-diagram.jpg"><img style="cursor:pointer; cursor:hand;width: 450px; height: 303px;" src="http://www.blogcdn.com/www.autobloggreen.com/media/2008/01/two-mode-diagram.jpg" border="0" alt="" /></a><div><br /></div><div><span class="Apple-style-span" style="font-size: medium;">2 mode powertrain, The  previous post shows mild hybrid and diagram .

The system consists of twin, active-cooled electric motors integrated into the automatic transmission. Energy to power the motors comes from a 300V nickel-metal hydride battery pack, which consists of nickel metal hydride modules and is packaged behind the second-row seat below the cargo floor.</span></span><p style="font-family: Arial, Helvetica, sans-serif; color: rgb(0, 0, 0); "><span style="font-family:Arial;"><span class="Apple-style-span" style="font-size: medium;">In the first mode, at lower speed and lighter loads the 2-Mode Hybrid operates in one of three ways depending on conditions and battery charge level: all-electric power, internal combustion engine power or a combination of the two. All reverse operation is driven solely by the electric motors.</span></span></p><p style="font-family: Arial, Helvetica, sans-serif; color: rgb(0, 0, 0); "><span style="font-family:Arial;"><span class="Apple-style-span" style="font-size: medium;">The second mode is used primarily to optimize fuel economy at highway speeds. It provides electric assist in addition to combustion engine power when conditions demand it, such as trailer towing and climbing steep grades, and to allow the engine to run at its most efficient point under less-demanding conditions.</span></span></p><p style="font-family: Arial, Helvetica, sans-serif; color: rgb(0, 0, 0); font-size: 9pt; "><span style="font-family:Arial;"><span class="Apple-style-span" style="font-size: medium;">No engine speed changes are necessary for the mode shift to occur. The result is exceptionally smooth, seamless acceleration and responsiveness. At all times, the Hybrid Optimizing System (HOS) collects torque-based data, deciphers it, then determines the most fuel-efficient means of propelling the 2-Mode Hybrid</span></span><span style="font-family:Arial;">.</span></p></span></div><div><br /></div><div><br /></div><div><br /></div><div><br />© yankandpaste®</div><div class="blogger-post-footer">© yankandpaste®.blogspot.com<img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8576780862978816982-9122455802864409642?l=yankandpaste.blogspot.com'/></div>Unnihttp://www.blogger.com/profile/11647147116239881353noreply@blogger.com0tag:blogger.com,1999:blog-8576780862978816982.post-75438970334024347112009-04-30T22:22:00.000-07:002009-04-30T22:27:43.037-07:00Greenlings: What is a mild hybrid?<div><span class="Apple-style-span" style="color: rgb(34, 34, 34); line-height: 17px; "><span class="Apple-style-span" style="font-family: arial;"><span class="Apple-style-span" style="font-size: medium;">People like to categorize the world. It helps our brains figure stuff out, because we can only manage so much information. Lumping things into bins helps get information down to a manageable level. Unfortunately, most things don't readily fall into discrete categories. Hybrid drive technology is one of them, but we'll try anyway. On the continuum that is hybrid technology, we typically break things down into strong, mild and micro-hybrids. Strong hybrids include systems like Toyota's hybrid synergy drive, Ford's hybrid system and General Motors two-mode system. Micro-hybrids are really nothing more than automatic start stop systems.  Somewhere in between those groups lies the mild hybrid. The basic premise of the mild hybrid is the same as the strong hybrid. An electric motor/generator operate in parallel with the internal combustion engine to provide additional drive torque as well as regenerative braking. The primary difference lies in the power and energy capacity of the electrical side of the system. Continue reading about mild hybrids after the jump. </span></span></span><span class="Apple-style-span" style="font-family: arial;"><span class="Apple-style-span" style="font-size: medium;"><br /></span></span></div><div><span class="Apple-style-span" style="color: rgb(34, 34, 34); line-height: 17px;"><span class="Apple-style-span" style="font-family: arial;"><span class="Apple-style-span" style="font-size: medium;"><br /></span></span></span></div><div><span class="Apple-style-span" style="color: rgb(34, 34, 34); line-height: 17px;"><span class="Apple-style-span" style="font-family: arial;"><span class="Apple-style-span" style="font-size: medium;"> Why would an automaker create a mild hybrid system? Mainly to get some of the benefits of a hybrid system at a significantly lower cost and weight. Mild hybrids typically have a much smaller battery than a strong hybrid and a smaller, weaker motor/generator. The first manufacturer to build a system that fits into the mild category is generally considered to be Honda with it's Integrated Motor Assist (IMA) system as used in the </span></span><a href="http://www.autobloggreen.com/2009/03/10/2010-honda-insight-officially-priced-at-19-800/" style="color: rgb(30, 95, 14); text-decoration: none; outline-style: none; outline-width: initial; outline-color: initial; font-weight: bold; "><span class="Apple-style-span" style="font-family: arial;"><span class="Apple-style-span" style="font-size: medium;">Insight</span></span></a><span class="Apple-style-span" style="font-family: arial;"><span class="Apple-style-span" style="font-size: medium;"> and Civic. <br /></span></span></span></div><div><span class="Apple-style-span" style="color: rgb(34, 34, 34); line-height: 17px;"><span class="Apple-style-span" style="font-family: arial;"><span class="Apple-style-span" style="font-size: medium;"><br /></span></span></span></div><div><span class="Apple-style-span" style="color: rgb(34, 34, 34); line-height: 17px;"><span class="Apple-style-span" style="font-family: arial;"><span class="Apple-style-span" style="font-size: medium;">Since the Insight debuted in 1999, General Motors has released two different mild hybrid systems, one that was briefly offered in the Silverado hybrid in 2005-6 and the more recent belt-alternator-starter (BAS) system offered on several models. Mercedes-Benz and BMW have also co-developed a system of their own that will debut this summer on the S400 BlueHybrid and then on the new 7-series.  The GM system uses what is essentially a beefed up alternator and modified belt drive system to provide some additional drive torque to the engine as well as re-start it. Other systems, such as those from Honda and Mercedes, use a disk-shaped motor-generator sandwiched between the engine and transmission to provide the same functionality. The motor also takes the place of the torque converter in the transmission.  </span></span></span></div><div><span class="Apple-style-span" style="color: rgb(34, 34, 34); line-height: 17px;"><span class="Apple-style-span" style="font-family: arial;"><span class="Apple-style-span" style="font-size: medium;"><br /></span></span></span></div><div><span class="Apple-style-span" style="color: rgb(34, 34, 34); line-height: 17px;font-family:arial;font-size:13px;"><span class="Apple-style-span" style="font-size: medium;">During deceleration the mild hybrid system can also provide some regenerative braking capability. Because the battery pack is generally smaller than what you find on a strong hybrid, the ability to store energy to drive the vehicle is limited. However, the Mercedes-BMW mild hybrid is using the electrical power in a different way. The energy stored in the battery is being used to drive vehicle electrical systems such as audio, windows, HVAC and others. By using recaptured kinetic energy, the load on the alternator is reduced, cutting parasitic losses.  The Mercedes mild hybrid system will be the </span><a href="http://www.autobloggreen.com/2009/02/16/mercedes-benz-s400-bluehybrid-arriving-in-the-u-s-this-summer/" style="color: rgb(30, 95, 14); text-decoration: none; outline-style: none; outline-width: initial; outline-color: initial; font-weight: bold; "><span class="Apple-style-span" style="font-size: medium;">first mainstream hybrid to use a lithium ion battery</span></a><span class="Apple-style-span" style="font-size: medium;">. The Continental-supplied battery is mounted under-hood and is the same size as the traditional lead-acid starter battery, which is replaced by the lithium unit. In 2010, GM plans to launch a second-generation version of its mild hybrid. The new version increases the motor power from 5 to 15 kW and the current nickel metal hydride battery is replaced by a higher capacity, lighter lithium ion unit.  While a mild hybrid system can't drive the vehicle on electricity alone, it still provides benefits. Like direct injection and turbocharging, it allows the automaker to downsize the base engine while maintaining the same performance level. The combination of the reduced peak output of the engine and eliminating engine idle can contribute fuel consumption savings of up to 15 percent in urban driving and 8-10 percent overall. While not as significant as a strong hybrid, these benefits come at a much lower cost in mild hybrid form.</span><br /></span></div><div><span class="Apple-style-span" style="color: rgb(34, 34, 34); line-height: 17px;font-family:arial;"><br /></span></div><div><span class="Apple-style-span" style="color: rgb(34, 34, 34); line-height: 17px;font-family:arial;">From :<span class="Apple-style-span" style="color: rgb(0, 0, 0); line-height: normal; font-family:Georgia;"><a href="http://www.autobloggreen.com/2009/04/30/greenlings-what-is-a-mild-hybrid/">http://www.autobloggreen.com/2009/04/30/greenlings-what-is-a-mild-hybrid/</a></span></span></div><div><span class="Apple-style-span" style="color: rgb(34, 34, 34); line-height: 17px;font-family:arial;font-size:13px;"><br /></span></div><div><span class="Apple-style-span" style="color: rgb(34, 34, 34); line-height: 17px;font-family:arial;font-size:13px;"><br /></span></div><div><span class="Apple-style-span" style="color: rgb(34, 34, 34); line-height: 17px;font-family:arial;font-size:13px;"><span class="Apple-style-span" style="color: rgb(0, 0, 0); font-family: Georgia; font-size: 16px; line-height: normal; "><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://www.blogcdn.com/www.autobloggreen.com/media/2008/02/x08pt_ar008-1280.jpg"><img src="http://www.blogcdn.com/www.autobloggreen.com/media/2008/02/x08pt_ar008-1280.jpg" border="0" alt="" style="cursor: pointer; width: 1280px; height: 989px; " /></a><br /></span></span></div><div><br /></div><div><br /></div>© yankandpaste®<div class="blogger-post-footer">© yankandpaste®.blogspot.com<img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8576780862978816982-7543897033402434711?l=yankandpaste.blogspot.com'/></div>Unnihttp://www.blogger.com/profile/11647147116239881353noreply@blogger.com0tag:blogger.com,1999:blog-8576780862978816982.post-32881080737770089332009-04-01T14:58:00.000-07:002009-04-01T22:52:15.260-07:00Why Indians Don't Envy Israel?<span style="font-weight: bold;">And Why</span><span style="font-weight: bold;"> Tharoor's Brief for Israel Is Not Convincing.</span><br /><br />Perhaps, it was a well-intended article, meant to instill sense to the senseless people who have been clamoring for an all-out war with Pakistan to take out the terrorist camps and to put an end to the terrorist strikes that have become so commonplace lately. I said perhaps. Perhaps because I still respect the author for his writings that used to uphold the plurality and secularism of India; for all that he has written against the growing clout of the majority fundamentalism in India. But then, I wrote perhaps. Perhaps because the Haaretz article does not read like one from the celebrated author and champion of Indian plurality, who once wrote if America is the melting pot of cultures, India is more like a thali meal, where each dish has its own character and taste and yet complements each other in making the meal a satisfying repast.<br /><br />India's Israel Envy, read the title, which the author later attributed to the Israeli newspaper editors. But, for all that one understands from the piece, the title just sums up what Mr. Tharoor says in so many words-a case of sour grapes.<br /><br />Look at the words used in the first paragraph. "As Israeli planes and tanks were exacting a heavy toll on Gaza, India's leaders and strategic thinkers were watching with an unusual degree of interest - and some empathy." Unusual degree of interest and some empathy from India's leaders and strategic thinkers, it says. For all that we know, our country and most of our leaders till very recently-that is until the BJP Government opened diplomatic channels with Israel-had their sympathies with the people of Palestine, for their just cause, for all their sufferings. And even now, the right-thinking people of this country who haven't lost sense of justice have their sympathies with the cause of Palestine. So, from where does this interest-isn't it such a positive word? Like watching a cricket match? I thought we watched terrorist attacks - government-sponsored and private - with anxiety, and not interest-come from? And empathy? Well, only Mr. Tharoor knows when did our sympathies for Palestine people transform into empathy for Israel.<br /><br />Mr. Tharoor's admiration for the Israeli action becomes clear as he goes on eulogizing Israeli determination in dealing with the Hamas. As if to show that he is not the only Indian charmed by the Israeli iron fist, he writes that the Indians have been nodding in appreciation and asking "why can't we do the same?"<br /><br />He continues:<br /><blockquote>"For many Indians, the temptation to identify with Israel was strengthened by the terrorists' seizure of the Chabad House, and the painful awareness that India and Israel share many of the same enemies. India, with its 150 million Muslims, has long been a staunch supporter of the Palestinian cause, and remains strongly committed to an independent Palestinian state. But the Mumbai attacks confirmed what has become apparent in recent years: The forces of global Islamist terror have added Indians to their target list of reviled "Jews and crusaders."<br />Just as Israel has frequently been attacked by rockets fired from across its border, India has suffered repeated assaults by killers trained, equipped, financed and directed by elements based next door, in Pakistan. When President George W. Bush's press secretary equated members of Hamas with the Mumbai killers, her comments were widely circulated in India."</blockquote><br /><br />After painfully building his argument that there are many parallels between India and Israel and cleverly putting India with the Western forces in the Us versus Them global war on terror, he declares: "Yet there the parallels end". And that line did make me hope that he was coming to the facts there. I thought he would tell us why we shouldn't put the terrorism in India and Israel in the same bracket. I thought he would tell us why people should stop eulogizing the Israeli determination and understand that what Israel is carrying out on Palestine and its people is another brand of terrorism-a state-sponsored, home-grown brand, and that Palestinians were forced to doing what they are doing now by decades of Israeli (with the active support and encouragement of the US) atrocities against the people of Palestine, that UN and the people of this world have been made mute-spectators to one of the worst human-right tragedies of our times.<br /><br />Instead, he goes on to build a rather baffling argument:<br /><blockquote>"Israel is a small country living in a permanent state of siege, highly security-conscious and surrounded by forces hostile to it; India is a giant country whose borders are notoriously permeable, an open society known for its lax and easygoing ways."<br /></blockquote>The problem is with our country and our people, he says. He forgets that we are fighting different issues; except for the Islamic prefix (well, then, who said Gujarat pogrom was not a terrorist activity? What about Malegaon? Babri Masjid?), there isn't much in common. I wish I were a little too naïve to think that Sashi Tharoor doesn't know these.<br /><br />What is more baffling is his parroting the Sangh Parivar line of India being a soft state. He forgets the realities. He forgets what India has been doing in fighting terrorism. He forgets that we cannot afford to have a tough-state label at the cost of basic human rights. And, most surprisingly, he doesn't talk about the causes of terrorism at all; he talks only about the symptoms and addressing the symptoms. Baffling, isn't it? A friend suggested that he might have lost his senses the moment he joined Indian politics; not that I think all our politicians are senseless, but I liked that observation for want of anything better to explain Tharoor's rather nonsensical article.<br /><br />After explaining in length about why we "cannot" do what Israel is doing; he concludes:<br /><blockquote>"Yet, when Indians watch Israel take the fight to the enemy, killing those who launched rockets against it and dismantling many of the sites from which the rockets flew, some cannot resist wishing that they could do something similar in Pakistan. India understands, though, that the collateral damage would be too high, the price in civilian lives unacceptable, and the risks of the conflict spiraling out of control too acute to contemplate such an option. So Indians place their trust in international diplomacy and watch, with ill-disguised wistfulness, as Israel does what they could never permit themselves to do."<br /></blockquote>Again, look at the words; whoever said words do matter was so right I realize as I watch, disappointed, another icon, created by powerful words, being demolished by his own words. Take the fight to the enemy, he wrote, betraying his sympathies for Israeli action. Suddenly, he sounds so pedestrian, pretends like someone who has forgotten his history lessons, like one of those next-door knicker-wallahs who make sweeping statements like every madrassas in this country has terrorists in them and should be taken out along with the terrorist camps across the border. Yeah, those knicker-wallahs have long been talking about taking a few leaves out of the Israel's anti-terrorist operations.<br /><br />Mr. Tharoor goes on to say that Indians watch Israel doing what they could never permit themselves to do, with ill-disguised wistfulness! And the reasons why we CANNOT do to Pakistan what Israel does to Palestine, the nuclear warheads Pakistan has; otherwise, we could have done what the US has done in Afghanistan and Iraq, what Israel continues to do with Palestine. As I finished reading the piece, I couldn't help wondering whether he has really lost his senses. Perhaps.<br /><br /><br />© yankandpaste®<div class="blogger-post-footer">© yankandpaste®.blogspot.com<img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8576780862978816982-3288108073777008933?l=yankandpaste.blogspot.com'/></div>Abhilashhttp://www.blogger.com/profile/17205474722911410887noreply@blogger.com1tag:blogger.com,1999:blog-8576780862978816982.post-23533445181984647002009-03-31T07:33:00.000-07:002009-03-31T07:37:33.667-07:00Hybrids as per cafe<div><div>Power Split Hybrid</div><div><br /></div><div>The Power Split hybrid (PSHEV) is described as a full or a strong hybrid since it has the ability to move the vehicle on electric power only. It replaces the vehicle’s transmission with a single planetary gear and a motor/generator. A second, more powerful motor/generator is directly connected to the vehicle’s final drive. The planetary gear splits the engine’s torque between the first motor/generator and the final drive. The first motor/generator uses power from the engine to either charge the battery or supply power to the wheels. The speed of the first motor/generator determines the relative speed of the engine to the wheels. In this way, the planetary gear allows the engine to operate independently of vehicle speed, much like a CVT. The Toyota Prius and the Ford Hybrid Escape are two examples of power split hybrid vehicles.</div><div><br /></div><div>2-Mode Hybrid</div><div><br /></div><div>The 2-mode hybrid (2MHEV) is another strong hybrid system that has all-electric drive capability. The 2MHEV uses an adaptation of a conventional stepped-ratio automatic transmission by replacing some of the transmission clutches with two electric motors, which makes the transmission act like a CVT. Like the Power Split hybrid, these motors control the ratio of engine speed to vehicle speed. But unlike the Power Split system, clutches allow the motors to be bypassed, which improves both the transmission’s torque capacity and efficiency for improved fuel economy at highway speeds. This type of system is used in the Chevy Tahoe Hybrid.</div><div><br /></div><div>Plug-In Hybrid</div><div><br /></div><div>Plug-In Hybrid Electric Vehicles (PHEV) are very similar to other strong hybrid electric vehicles, but with significant functional differences. The key distinguishing feature is the ability to charge the battery pack from an outside source of electricity (usually the electric grid). A PHEV would have a larger battery pack with greater energy capacity, and an ability to be discharged further (referred to as “depth of discharge”). No major manufacturer currently has a PHEV in production, although both GM and Toyota have publicly announced that they will launch plug-in hybrids in limited volumes by 2010.</div><div><br /></div><div><br /></div><div>From :<a href="http://www.nhtsa.dot.gov/portal/site/nhtsa/menuitem.43ac99aefa80569eea57529cdba046a0/">http://www.nhtsa.dot.gov/portal/site/nhtsa/menuitem.43ac99aefa80569eea57529cdba046a0/</a></div><div><br /></div><div><br /></div></div><div><br /></div>© yankandpaste®<div class="blogger-post-footer">© yankandpaste®.blogspot.com<img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8576780862978816982-2353344518198464700?l=yankandpaste.blogspot.com'/></div>Unnihttp://www.blogger.com/profile/11647147116239881353noreply@blogger.com0tag:blogger.com,1999:blog-8576780862978816982.post-67349019334917819522009-02-19T00:14:00.000-08:002009-02-19T07:53:03.706-08:00The new electric era : 2010<div>Every car maker asking money to govt, what went wrong ? and <span class="blsp-spelling-error" id="SPELLING_ERROR_0">whatz</span> next</div><div><br /></div><div>Yes its new era beginning, people are looking for <span class="blsp-spelling-error" id="SPELLING_ERROR_1">EVs</span> ( electric vehicles ).

Essentially, a hybrid is a vehicle that is designed to use gasoline as its primary fuel and electricity as a supplement. At lower speeds and light engine loads, some hybrids use only electricity. At higher speeds or rates of acceleration, they operate in a “blended” mode, with both the larger gas engine and smaller electric motor running. Even the most efficient hybrids on the road only get a battery-powered boost at low speeds, while most of the time still burning gas. So while a hybrid is more efficient than a conventional internal combustion engine, under normal driving conditions it will use more gas than an E-REV operating in all-electric mode.<br /><br /><br />Volt would be the first car to flip that equation. In fact, Volt's unique advanced design has helped establish a new category &mdash; Extended-Range Electric Vehicles or E-REVs. Basically, an electric motor would drive the vehicle at all times. So you'll be accelerating, driving on the highway, going uphill &mdash; all the normal driving requirements &mdash; propelled by electric power. A small gasoline engine and a generator would kick in when the battery power is depleted after driving up to 40 miles. The gas engine and generator then produce all the electricity needed to keep driving for hundreds of miles. It's this range-extending technology that makes EREV so unique. Think of EREV as an electric car that can generate its own electricity, allowing you to continue efficiently without any worry of running out of power.<br /><br /><br />Volt would be the first car to flip that equation.

The engine will not fully charge the battery (this would be an inefficient use of gasoline). Rather, it will provide enough juice to keep the car going until it can be fully charged in a household outlet. This kind of advanced propulsion system means there are fewer demands on the engine, which can be sized, engineered and controlled to operate in a narrow range of rpm and at peak efficiency.<br /><br /><br />Because the engine drives a generator that will run at a constant speed, the power band can be optimized for maximum fuel efficiency and lower emissions.

Bob previously worked as an engineer at a large company doing work that is related to how Fantastic Cheese will be manufactured.<br /><br /><br />Bob has received some financial backing from a respected venture capital firm called New Ideas Capital. New Ideas Capital states in their Investing Policy Statement that they are focusing on investing in cheese related companies because New Ideas Capital believes that cheese is a future growth sector however New Ideas Capital will not discuss their investment in Bob’s Fantastic Cheese.<br /><br /><br />A large respected military food packaging and catering company called War Food’s, Inc. has provided some funding to Bob to help Bob further develop Fantastic Cheese. Bob has agreed provide War Food’s Inc an exclusive for Fantastic Cheese for certain military food products.<br />Nobody has seen or tasted Bob’s Fantastic Cheese although Bob has started to build his Fantastic Cheese factory.<br /><br /><br />An independent company has certified that Bob’s factory is capable of propagating Bob’s proprietary baseline cheese starter bacterial culture. Bob claims his cheese starter bacterial culture contains a unique balance of enzymes that interact in the curdling process in such a way that the cheese becomes Fantastic Cheese.<br /><br /><br />An independent company has certified that Bob’s factory contains cooking vats capable of maintaining a constant temperature within one quarter of one degree centigrade. Bob claims it is critical to be able to maintain an exact temperature during the cooking process to manufacture Fantastic Cheese.<br /><br /><br />A very large portion of the cheese produced worldwide is used for pizza toppings. Therefore the potential worldwide market for Fantastic Cheese as a pizza topping is fantastic if Fantastic Cheese is as fantastic as Bob claims. Every pizza maker will want Fantastic Cheese because Fantastic Cheese will render all other cheeses obsolete.<br /><br />Given all the above facts, why would Bob license his Fantastic Cheese to a small pizza operator under terms that allows the small pizza operator to be the only pizza operator to use Fantastic Cheese?<br /><br />from : <a href="http://gm-volt.com/2009/01/04/eestor-gets-a-trademark-patent-on-eesu-and-provides-specs-for-a-24v-eesu/">http://gm-volt.com/2009/01/04/eestor-gets-a-trademark-patent-on-eesu-and-provides-specs-for-a-24v-eesu/</a> Read comments<br /><br />© yankandpaste®<div class="blogger-post-footer">© yankandpaste®.blogspot.com<img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8576780862978816982-7981672822802238084?l=yankandpaste.blogspot.com'/></div>Unnihttp://www.blogger.com/profile/11647147116239881353noreply@blogger.com0tag:blogger.com,1999:blog-8576780862978816982.post-34238339859961568562008-12-28T22:03:00.000-08:002008-12-28T22:22:28.183-08:00Linux can't cure a stupid and it's not a medicine for stupidity<div><span class="Apple-style-span" style=" white-space: pre-wrap; font-family:-webkit-monospace;font-size:13px;">These were the words, i saw in one of the start up company, written on white board with some marker.

So we need more ways to produce, store electricity and should be affordable.<br /><br />Second, we cant eat electricity as of now. We need more food. We have more people and less land, so we need to make more food from less. Another potential area for next gen.<br /><br /><br />Health, Last day i was watching a movie on clones. The theme was like, when you take insurance policy, they will take a sample and make a clone of you. Once you need any organ or something else, they use the clones one ( saying you won a lottery move them to an island and kill them ). To be true i fear this movie is going to be true in this era.<br /><br /><br />Lets see what all this era offers but as first ones, yes battery technologies are hot now, now computer is a normal thing and its no longer the high pay job.Its a skill every one need to make your work better.<br /><br /><br />Lets be back to manufacturing and research. Make more resources.<br /><br />As i was reading the land is mars is good for asparagus, We can expect an era where asparagus is made in mars and space shuttles running back and forth for transportation.<br /><br /><br />© yankandpaste®<a href="http://www.blogger.com/posts.g?blogID=8576780862978816982"><br /></a><div class="blogger-post-footer">© yankandpaste®.blogspot.com<img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8576780862978816982-115184740840621436?l=yankandpaste.blogspot.com'/></div>Unnihttp://www.blogger.com/profile/11647147116239881353noreply@blogger.com0tag:blogger.com,1999:blog-8576780862978816982.post-19080288664398943332008-12-09T22:05:00.000-08:002008-12-09T22:17:12.690-08:00Next Big word for USAIn west, the words yoga, karma, guru etc has found own place. I love to say the next big word which is going to be the life style for west is "<strong>Swadeshi movement</strong>"<br /><br />Why ? USA started with industries and then they lost the track. For more profits they outsourced the quality jobs and only sales and some other minimum pay jobs remained.<br /><br />The industries said they are getting profits.People who got profits brought land and land owners got money and all the real-estate eco system got the money. They never cared that all the quality jobs are vanishing. Now they are understanding that there is no customers who can afford the services/products and there is no market.<br /><br />Why ? Because quality jobs vanished and now all get minimum pay jobs and they cannot afford.<br /><br />Do this has any relation with next big word ? yep lets see whatz swadeshi movement<br /><br />wikipedia says :<br /><br /><a class="mw-redirect" title="Mahatma Gandhi" href="http://en.wikipedia.org/wiki/Mahatma_Gandhi">Mahatma Gandhi</a> described Swadeshi as "a call to the consumer to be aware of the violence he is causing by supporting those industries that result in poverty and harm to workers and to humans and other creatures."<br /><br />Gandhi recognised that <a title="Social alienation" href="http://en.wikipedia.org/wiki/Social_alienation">alienation</a> and <a title="Exploitation" href="http://en.wikipedia.org/wiki/Exploitation">exploitation</a> often occur when production and consumption are divorced from their social and cultural context, and that local enterprise is a way to avoid these problems. "Swadeshi is that spirit in us which requires us to serve our immediate neighbours before others, and to use things produced in our neighbourhood in preference to those more remote. So doing, we serve humanity to the best of our capacity. We cannot serve humanity by neglecting our neighbours<br /><br /><br />Now USA has to make things and not import. Have to shift business back to US and not say we outsourced fabrication or other stuff.<br /><br />Lets look for more "Made in USA" and let people support the move by spending on local products.<br /><br /><br />© yankandpaste®<div class="blogger-post-footer">© yankandpaste®.blogspot.com<img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8576780862978816982-1908028866439894333?l=yankandpaste.blogspot.com'/></div>Unnihttp://www.blogger.com/profile/11647147116239881353noreply@blogger.com0tag:blogger.com,1999:blog-8576780862978816982.post-79868141247422923922008-11-19T22:42:00.000-08:002008-11-19T23:23:14.263-08:00The New Chevy Volt concept - OPEN VOLTIt looks the 25b TARP money is not coming to big 3 American Auto makers. So lets looks for an alternative idea for Chevy Volt program. The reason is once GM goes bankrupt, they cant come up with it. If they are able then i am not sure how good it will be.<br /><br />Alternatives ? OPEN VOLT - <span class="blsp-spelling-error" id="SPELLING_ERROR_0">Thatz</span> a nice thought<br /><br />Lets follow Linux model combined with <span class="blsp-spelling-error" id="SPELLING_ERROR_1">IETF</span> model (hybrid).<br /><br />TARP/Other funding money goes to NASA or some good agency ( NASA because it can use space technology for use of men and VOLT for space exploration) . All Specifications and designs come from Central agency for the platform. Its like Linux kernel. Then any vehicle manufacturer can make Volt ( like Toyota Volt v 1.2 , Honda Volt 6 , Hyundai Volt ABC etc ). They have to follow the OPEN VOLT specifications and they can design there own body according to aerodynamics . Same with Interior etc where the specs will not be tight on and allow creativity ( this is like distributions in Linux ).<br /><br /><br />All good practices will be taken back to Central agency and will be done like <span class="blsp-spelling-error" id="SPELLING_ERROR_2">IETF</span> drafts or Jabber <span class="blsp-spelling-error" id="SPELLING_ERROR_3">XEPs</span> or Java <span class="blsp-spelling-error" id="SPELLING_ERROR_4">JSRs</span>. It will go through review and tests and the ones which qualifies comes out as specifications and gets into new version of OPEN VOLT specifications - something like RFC. As this is a proved model in computers ( the <span class="blsp-spelling-error" id="SPELLING_ERROR_5">IETF</span> and RFC ) , we can use the same concepts for OPEN VOLT.<br /><br />So when we buy a VOLT get the list of specifications it follows and we have the freedom to choose vendor on core components - ex: battery, Generator, Electric Engine etc - and Specifics (non core specifications parts) from my distributor ( ex: Honda , Toyota etc ).<br /><br />Put your votes on the OPEN VOLT !!<br />Lets write open letter to Obama as this idea is going to be saving our future and no distributor ask for money in future.<br /><br />© <span class="blsp-spelling-error" id="SPELLING_ERROR_6">yankandpaste</span>®<div class="blogger-post-footer">© yankandpaste®.blogspot.com<img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8576780862978816982-7986814124742292392?l=yankandpaste.blogspot.com'/></div>Unnihttp://www.blogger.com/profile/11647147116239881353noreply@blogger.com0tag:blogger.com,1999:blog-8576780862978816982.post-50605929261353441712008-11-19T22:38:00.000-08:002008-11-19T22:41:45.349-08:00Globalization and economic crisisA video forwarded by a friend, Make sense in some aspects.<br /><br />Its a good watch for Americans and mostly western people.<br /><br /><embed id="VideoPlayback" src="http://video.google.com/googleplayer.swf?docid=4343898391323537541&hl=en&fs=true" style="width:400px;height:326px" allowFullScreen="true" allowScriptAccess="always" type="application/x-shockwave-flash"> </embed><br /><br />NB: Please note the english used is Tamglish ( tamil - english )so clarification please let me know :-)<br />© yankandpaste®<div class="blogger-post-footer">© yankandpaste®.blogspot.com<img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8576780862978816982-5060592926135344171?l=yankandpaste.blogspot.com'/></div>Unnihttp://www.blogger.com/profile/11647147116239881353noreply@blogger.com0tag:blogger.com,1999:blog-8576780862978816982.post-27378547259323855282008-11-11T14:50:00.000-08:002008-11-11T15:09:48.822-08:00Bubbles ( kumilakal )Was going through a presentation, Bit small one ( not sure on the author but it was rotating by email )<br /><br />Preface :<br /><br />This is a small story. In starting you may be bit confused but once you go till end of the story, everything will be fine.<br /><br />Lets start reading.<br /><br />In a small island ( not iceland ) there are 3 inhabitants.<br /><br />Kunjumoosa<br />Kunjunni<br />and Kochutresya<br /><br />Kunjunni and Kochutresya doesn't own any land but both have a dollar each in hand.<br />kunjumoosa does not have any money, but island is owned by him.<br /><br />Kunjunni got a desire to buy the island. He gave a dollar and brought the island <br /><br />Balance sheet :<br /><br />Kunjunni has a dollar valued island<br />Kunjumoosa has a dollar<br />Kochutresya has a dollar<br /><br />Total Value in island : 3 dollar<br /><br />Seeing this, kochutresya also want to buy the island.But she was sure she cant get that for a dollar. She borrowed a dollar from kunjimoosa and brought the island for $2.<br /><br /><br />Balance sheet :<br /><br />Kunjunni has two dollar valued island<br />Kunjumoosa has a dollar to get from Kochutresya.<br />Kochutresya has two dollar valued island but she got a debt of a dollar.So she has a dollar net value.<br /><br />Total value in island : 4 dollar<br /><br />Kunjumoosa felt sad on the land sale because he felt it was too worthy and its going up. So he decided to buy back. <br /><br />He took loan of two dollar from Kunjunni and brought the island for three dollar. Two dollar cash and one dollar as credit of the one dollar she loaned before.<br /><br />Balance sheet :<br /><br />Kunjunni has two dollar value - which is loaned to kunjimoosa<br />kunjumoosa has three dollar valued island.<br />Kochutresya has two dollars.<br /><br />The bubble went big and big. Every one happy and every in profit.<br /><br /><br />Days passed, Kujunni started thinking again .. do real estate rise this much ? do i get the money back ?<br /><br /><br />Kunjumoosa and kochutresya also started thinking - d this land cost this much ? <br /><br />Kunjunni asked the money back. Kunjumoosa tried to sell. <br />The market for land went down.now its back to a dollar. <br /><br />Konjumoosa because bankrupt and gave away the land to kunjunni and declared chap: 11.<br /><br />Balance sheet :<br /><br />Kunjunni has dollar valued land.<br />kunjumoosa - 0 dollar.<br />Kochutresya has two dollars<br /><br /><br />Total value in island : 3 dollar<br /><br /><br />End of story.<br /><br />Tailpiece:<br /><br />Nobody knows when the bubble bursts. The person with cash at time of bust gets it. So don't worry if bank doesn't give you a loan. They want to secure cash in hand for now.<br /><br />Management fundus will say kunjimoosa to sell the island divided etc but we want to make story simple so no side lines added. <br /><br />special thanks : Gopakumar<br /><br />© yankandpaste®<div class="blogger-post-footer">© yankandpaste®.blogspot.com<img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8576780862978816982-2737854725932385528?l=yankandpaste.blogspot.com'/></div>Unnihttp://www.blogger.com/profile/11647147116239881353noreply@blogger.com0tag:blogger.com,1999:blog-8576780862978816982.post-47137921305387678292008-10-28T22:52:00.000-07:002008-10-28T23:34:18.460-07:00Gods own county - Terrorists rulesKerala local news : Local people ( more criminals ) are getting recruited and trained for becoming terrorists in Kashmir. The news got importance when 2 of them got killed in an attack. <br /><br />The Local police, Govt and Political parties started working ( yes, Political parties just try to blame each other )<br /><br />The next is only my view and only my view and i am not expecting somebody to read but i am expressing my opinion using freedom for expression of opinion.<br /><br />This time when i was in India,I had a talk to most friends on the bomb blasts etc. <br /><br />One of the Opinions i herd : There is a feeling in Muslim community that they are targeted globally and this feeling get oil when they go as group and it get worse and results in attacks.<br /><br />Another one : They should understand they live in India and work for India. They are killing innocents.<br /><br />Another one : There are 3 truths : my truth, your truth and the truth.<br /><br />and goes on.<br /><br />My View :<br /><br />I think politicians in Kerala did helped these organizations to grow just thinking of vote banks because they get Muslim votes as bulk.For them this is wake up call to work for nation and think above Vote banks. <br /><br />I think a minority in Muslims may be doing all the bad things. Let me ask, what kind of reputation was there for normal swamis when Santhosh Madhavan case was going ? a lot asrams were attacked. Did they killed people ? or took the sufferings ? <br /><br />Do u think this wont happen with Muslims now ? and if they react same violence, its going to be loss for Muslims more because the belief of normal people get more strength.<br /><br />I know Muslims of India are of Indian orgin and they are even given more reservations than normal Hindus. Think of what happens in middle east and how non-Muslims are treated there. In India i am sure no Muslim get the same treatment like treatment of a non Muslim in a Muslim country.<br /><br /><br />I believe This is time for INDIAN MUSLIMS or i call them HINDU MUSLIMS ( where Hindu is that ahimsa culture ) tell or protest publicly against the minority who creates this problems. <br /><br />They should share the same feelings of the mother who said " WE DON'T WANT THE DEAD BODY OF THE SON WHO WORKED AGAINST THE NATION "<br /><br />NB: I feel Biharis and Mumbains also should share the same above feeling and the govt should declare Raj Thackeray (who tries to create split in Indians and make his party or presence - old divide and rule policy )as terrorist as the same standards they do against all the terrorists. <br /><br /><br /><br /><br /><br />© yankandpaste®<div class="blogger-post-footer">© yankandpaste®.blogspot.com<img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8576780862978816982-4713792130538767829?l=yankandpaste.blogspot.com'/></div>Unnihttp://www.blogger.com/profile/11647147116239881353noreply@blogger.com1tag:blogger.com,1999:blog-8576780862978816982.post-69001408182223573102008-10-27T21:01:00.000-07:002008-10-27T21:25:00.803-07:00GM Volt and Next killing time of Electric carI am big fan of GM VOLT. I love it than Prius or other ones. Reason : Its all electric ( new generation begins here )<br /><br />Now every body want to say they are in EV business. But back to numbers :<br /><br />Gas price back to $2 Gallon, GM almost near bankrupt - Do you think they will try to sell the Hybrids and the same old mantras ? or really they deliver Volt ?<br /><br />Another : Do volt going to be another North American car - yes i mean on Quality which suffer very heavily with the Asian ones. Built Quality, Durability ... <br /><br />I know a lot who already had American cars and now they don't want to be part of this bandwagon. They all shifted to the other side. Now its GM duty to get those back and it cant be done saying we have quality.<br /><br />Lets see how volt can bring them back ) I hear 2008 Malibu is lot better than old still they are miles away from Prius and Civics. Lest see How GM will close this gap.I am sure its not only price point<br /><br />GM VOLT : <a href="http://gm-volt.com/">http://gm-volt.com/</a><br />: <a href="http://en.wikipedia.org/wiki/Chevrolet_Volt">http://en.wikipedia.org/wiki/Chevrolet_Volt</a><br />: <a href="http://www.gm.ca/gm/english/corporate/green-by-design/vehicles/electric">http://www.gm.ca/gm/english/corporate/green-by-design/vehicles/electric</a><br /><br /><br />© yankandpaste®<div class="blogger-post-footer">© yankandpaste®.blogspot.com<img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8576780862978816982-6900140818222357310?l=yankandpaste.blogspot.com'/></div>Unnihttp://www.blogger.com/profile/11647147116239881353noreply@blogger.com0
