Pterofin at Bloom

Описание: A CSU Sacramento graduate and lifelong admirer of nature, Kempkey and his grandfather shared the same idea that someday there would be free renewable energy for everyone. In particular, Kempkey envied the efficiency of a bird's wing flapping through the air and the way fish fins slice through water. With one crazy idea in mind, he went to the local hobby shop and spent about fifty bucks on balsa wood, copper tube and rod, and glue. Many iterations later, Pterofin is a mechanical wing or fin that can pump water or generate electricity in a wide range of wind or water currents more efficiently, quietly, and sustainably.
