Developed by Hydrogen Fuel Cell Technologies, this car runs on hydrogen power supplied from a charger unit that stores the water (fuel). It comes with a handset for controls and offers five to seven minutes of playtime per two-minute (full) charge. Whereas similar models, such as the H-Racer, were more for education and demonstration purposes, this model is designed for play, according to Mark Bawtree of Horizon Fuel Cell Technologies. Launch date: September 2007.
