Eli5: Why do automobiles operate with diesel or petrol but not with water?
In: Physics
Water is not a fuel.
In the context of fuel, you can think of water as being the unusable ash produced by burning hydrogen.
You can use electrolysis to break water apart into hydrogen and oxygen, but it takes more energy to do that then you will get back from burning them again. This is why we can’t just invent a car that uses a tank of water to make its own fuel.
