A lot of chortling in some circles, now that General Motors has recalled its EV-1 electric 2-seater and reva going slow in India. Does this spell the end of the electric car? Hardly. But it does show that technological advances should not be rushed into production prematurely. And certainly not in response to exaggerated fears about climate catastrophes.
Detractors of the electric car point to the known reliability of the internal combustion engine (ICE) and assert that electronic emission controls and catalytic converters have achieved near-zero pollution. They are right; new cars hardly contribute to the pollution generated by other human activities like lawn mowing, leaf burning, fireplace smoke, etc. They are also correct in stating that the electricity needed to charge electric-car batteries, every 60 to 80 miles, will have to be produced somewhere, probably by a coal-fired power station that adds to air pollution.
Electric cars have got many benifits as compared to normal petrol or gas cars. An electric car is capable of much greater energy efficiency. The well-established technique of "regenerative braking" can recapture the energy of motion that is now dissipated (and wasted) in wheel brakes, and feed it back into the car batteries. The electric motors used to drive the wheels function also as electric generators that take energy from the wheels and convert it back into electric energy. In this way, the energy efficiency of the car is doubled or tripled. Depending on driving conditions, it should be possible to achieve up to about 80 miles per gallon of gasoline, without downsizing the vehicle or cramping the style and comfort of the passengers.
With soaring petrol prices and growing concern over greenhouse gas emissions, even the world's largest car manufacturers concede electric cars may be the solution to the globe's environmental and energy problems. But although the electric car allows drivers to use renewable energy, critics argue it will do little to slash emissions if it is run on brown coal-generated electricity.
Fortunately, there is a lot of competition in the automobile industry. Japanese companies are experimenting with different hybrid vehicle designs and putting them to the test in the consumer market. There is competition also in the battery industry. The common lead-acid battery is being improved to produce more power per pound and to withstand more recharging cycles. And there is a bewildering list of new types out there; batteries based on sulfur, zinc, lithium, or metal hydrides. May the best one win.
It’s official: Green car madness has taken over...

Hi I Like your idea but problem is that to produce steam we need coal or some fuel which will again lead to pollution. So i think Magnetic Train will be the best option in this regard. What do you think? I know establishment cost will be more. but it... |
