Japan’s Sanyo Corporation has developed the world’s first solar-powered airship. This airship is not manned and can be used for aerial photography. The body of the airship is 7 meters long, and the film is made of amorphous silicon solar cells. The power generated by the airship propels the propeller. The flying height is about 20 meters and the speed is 10 kilometers per hour.
