Via Inhabitat, I found out about the H-Racer from Horizon Fuel Cell Technologies, a toy car that runs off of hydrogen. The car is fueled through "a miniature solar-powered hydrogen refueling station that converts water to hydrogen using energy captured from the sun." The toy is getting a lot of attention in various media outlets as a front-runner to the supposedly oncoming rush of hydrogen automobiles. Priced at $80, this would make a great, battery-free Christmas present for your favorite car geek, young or old.
