you can't win with cars.

even though oil and stuff you need to make petrol and diesel from is going to run out soon, so will lithium which is in car batteries.

so if everyone in the world switched to electric cars the lithium wouldn't last long because ifevery1 did do that it would only last 10 years so then no more batteries could be made.

so what we do after that??????????????????????????

We use hydrogen powered cars

We obtain the hydrogen by farming genetically modified algae or by electrolysi using renewable energy or nuclear fusion.

Hydrogen powered engines are here now the challenge is in storing the hydrogen

No problem. Another of the benefits of lithium for electric vehicles is that it can and will be recycled from failed batteries.

I have to agree with Jake-the-peg. Hydrogen is the only real contender in the long run. Produced as he says, by algae, or electrolysis of water from green sources (wind farms etc).

The exhaust gas is water which can be split again. The oxygen from the electrolysis could be used for medical purposes etc.

I think governments should be throwing more resources into hydrogen cell research and using the taxes they keep claiming are to reduce global warming, to do so.

The oil fields will have replenished themselves by then!

Hydrogen will never be a practical fuel for small vehicles.
