I bought a Hydrocar fuel-cell hydrogen powered toy car last week; JC Penney was clearing them out and I got it for $10 (supposed to retail for $120). The manual is full of flowery talk about global warming because of carbon-based fuels, and that hydrogen power is the best solution. Well guess what, you have to use a battery pack to create the hydrogen. Then the hydrogen is converted back to electricity to power the car! If I directly hooked up the battery pack to the car's motor it would run faster and further! So why bother using the conversion to hydrogen? That's lost on these libtards who created the toy, or they're trying to put one over kids using these toys.
The fuel cell is neat though because it's reversible. Put some water in, connect an electrical supply and it generates hydrogen and oxygen. Then the hydrogen and oxygen fed into it will generate electricity and some water. But with a lot of waste in the conversion process!
That is kinda cool. And I get what you are saying about the car running better off the battery pack directly. But you know what would really make the thing scream? Put a little glow pug model airplane motor in it and run it on nitromethane.
