Oil is a regererative source, we just use it faster than it reproduces itself.
If all the cars of the world went electric, there'd be plenty of oil to go round.
Gearbox oil lasts longer than engine oil anyway
Oil is definitely not a regenerative source, It was produced in two breif periods in the earths history and it will never happen again. I have done a lot of research on oil and things are looking pretty grim. Peak oil has probably already happened if not its happening now, talking about taking food from poorer nations, its estimated the natuarally the world can only feed between 1.5 to 2 billion people without the use of fertilizers which are petroleum based (made from oil) the world population is now above 6 billion, thats 4 to 4.5 billion starving people, not cool..

thats a cool idea, but something that has given me the shits for a while is why cant you attatch an alternator to a pulley off the electric motor so the batteries dont go flat?
You cannot do this as the extra power required to turn the generator/alternator is more than it would put back into the batteries( nothing is 100% efficient) and even if it was there would be no point as you would just be transfering the power from batteries to generator and back again, It is something many people have asked me.
