      Water fulled cars have been talked about for a long time but no one has been able to find a way to make it work. So the idea is that you can split a water molecule and use the energy from that to fuel the car. The problem is that it takes tonnes of energy to split a water molecule.. more than you need to fuel a car. So water powered cars might be possible in the future… but not yet.
