Hydrogen Generator for my daily car

[JET]

That is exactly right. That little 1 qt container has enough hydrogen in it to drive your car a couple of miles, max. There is enough power in there to be equivalent to 2 pints of gas and that doesn't include the power necessary to split the water molecules!

Take some chemistry courses and it will become much more clear. Hydrogen and oxygen like to be together, it takes a fair amount of energy to split them apart. Water is very stable, so it takes a lot of energy. Things that aren't so stable (gasoline for example) split apart easily.

The amount of energy in an equal amount of hydrogen and gas are also very different. Hydrogen atoms are also MUCH smaller than oxygen atoms, so the amount of hydrogen you can get out of water is pretty small compared to the amount of water going in.

I am guessing the "water car" has quite a few batteries in it to provide the energy to make the hydrogen and also could not make as much electricity as it uses. I bet the car would get far just from the electrical power it uses than it could making hydrogen.

Hydrogen can currently be made pretty easily, it just takes too much energy to produce it.
