BATTERY-DRIVEN TYPE ELECTRICITY-POWERED CAR

摘要

A battery-driven type electricity-powered car travels with electric energy generated by water reserved in a tank on the roof thereof. The power generation is effected by the rotation of waterwheel by the head drop of water from the tank. The water after use in the power generation is pumped up into the tank, thereby attaining a cyclic usage of water. Further, the battery is recharged by a photovoltaic panel disposed side by side.
