Go Green with The First Salt Water Powered Mini-Car! As the smallest, least expensive, not to mention first fuel cell car to be powered by saltwater, the Salt Water Fuel Cell Car gives children a chance to learn about new forms of clean energy, while building and powering their very own toy: Just add saltwater and go!
