The technology is not ready for that. Too heavy, small autonomy, very high tech (susceptible to failure). There is also the safety issue, I would not like to be near a fully charged battery pack when another two tons car smash it. And of course, the main reason, which is purely dictated by those who makes money from oil.
But why fully electric car when there are so much to do with the classic one. Hybrid cars are a fair option. Think of how much energy is wasted when breaking. Think of the efficiency of the engine, it's well below 50%. Why not perfecting 6 stroke engine? Why not using more hybrid cars? Why not try to change the driving style of many truck drivers? Let me tell you one story about that. One good friend of mine which is a very bright engineer at DAF started to teach driving to some very old truck drivers. Imagine how funny is that, especially he's quite young. By studying all the parameters of the truck (gear ratios, fuel injection maps, torque demands vs engine speed, etcetc.) he instructed drivers how to drive economically, meaning when is the proper moment to change gear, how to accelerate, how to slow down, etc. The results were astonishing, on a simple 100km test (with the same car, same load) it consumed with aprox. 20% less fuel when driving "economically". All the fuel saved over one year for one truck, only by changing the driving style, was almost 10K euro.

Truck and bus drivers floor the gas pedal so most of the fuel produces black smoke.
Have you noticed airplanes? They used to fly at max power for the first hour which wasted a lot of fuel.
Now some takeoff at nearly full power then throttle back soon to reduce waste. Then they are also quieter.

I think it is because the battery is very infectant and not very effective.

as they work only upto limited time.. and they need solar or... other resource back up...
resent advances in battery technologies makes things somewhat satisfactory...
Added after 2 minutes:
U know ?? with electronic device advancements greatly effects the battery systems. with advancements in photo voltaic device technologies efficient storage mechanisms are being built up..

Hello friend,
Fuel such as petrol, diesel r non - renewable resources of energy and also cause much pollution. Saving such fuel can extend the limit (years) of their extinction. But we have to make such a fuel which should be eco - friendly, renewable, efficient and economical. Also process of producing such fuel should not cause pollution.

You are right. But I don't know any alternative, better of worst, that could fulfill the energy requirements of this world at the level at which fosil fuel does. And by the way, there is another theory about the oil: http://en.wikipedia.org/wiki/Abiogenic_theory . Of course, proving that right would be even worse, meaning endless pollution.

Does we inefficient to find an alternate to oil?
No, I dont think so. There is something behind it.
Whenever there is a need there is a solution.
This is law of nature

Does 6 billinon bunch really need more energy ?
I think effort should be put to reduce transportaion needs first - thus resulting in less energy consumption. I make 80 km trip every day towards office and back. But if virtual office tech will be ready - i wont do that at all.
And energy saving tech.
Of course theories behind TNC can be true . It is natural for them to earn money doing nothing. Like least part of the world doing that everyday.
And speed , after all do we need be in hurry? There is much to see if we find time time to look around.

This is the main reason behind this, apart from oil, car manufacturers have invested so much money in oil based cars so even they don't like this idea. Otherwise all technical problems associated with battery powered cars can be solved with proper research may be most of them have been already solved but not visible to us. |
But what if oil runs off ?
