난이도 & 준비물

Whilst looking up the answer to another question using Google regarding the water output from a normal internal combusted engine powered car, I noticed that - to my surprise - all the top hits were about water powered cars . Cars that run on water are actually a thing apparently! What are water powered cars? How exactly do they work?

처리 내용

Simple answer - they are a hoax, and they don't work. The only way to power a car with water is to electrolyse the water into Hydrogen and Oxygen using an external power source (and it uses a lot of energy to do this), store the Hydrogen in the car and use that (with oxygen from the atmosphere) to power a Hydrogen fuel cell - the output from which is water and energy. Like every other system, there are losses involved, so you always get less energy out than you put in - that's a fundamental law of physics...
