This little vehicle runs on clean hydrogen fuel using a reversible Polymer Electrolyte Membrane (PEM) fuel cell. Called the Hydrocar, the kit’s fuel cell unit combines water electrolysis and fuel cell functions into one nefty device. You only need to add water to the tank located at the rear of the car.
The car independently steers itself and when it hits a barrier a cool blue LED light flashes from inside the cockpit. Price tag? A hefty $84.95 for the Hydrocar toy.
