The first electric car powered by saltwater will soon be rolling through European cities. Nanoflowcell, a Lichtenstein based car manufacturer, has just received approval to start testing its innovative electric car on streets and highways in Germany. The car produces power similar to a hydrogen cell car. Liquid is sent from one tank, through a membrane, and into another tank, which creates energy that is stored and distributed by super capacitors. The car debuted earlier in March at the Geneva Motor Show.
