Eco Factor: Solar power system charges Mindstorms robots.
In an age where clean energy systems are fast penetrating our lives, why should our bots remain aloof? Dexter Industries has devised a solar panel system called dSolar Systems that powers your Mindstorm kit. The 9V/250mA panel is compatible with Lego Mindstorms NXT robots and comes equipped with capacitor packs, battery and a connector for easily hitching the solar panel arrays to the robot. The solar power system is priced at a mere $90.
