I got one of these sittin around my house somewhere...pretty cool little car.. I might have to make a video to show how it works...
A short break down of how this rc works....
Theres a fueling station which you put water in and it seperates the h20 into hydrogen and oxygen using a solar panel..
It stores the hydrogen in a pump in which you pump into a balloon in the car.
From there the car turns the hydrogen to electricity and stores it in capacitors which in turn powers themotor to the wheels and steering servos..
Also the radio is charged by the solar panel..
