Beaver Dams Inspire Fish-Friendly Hydropower Design

Publication: National Geographic News   Date: July 15, 2005   View Article

Hydropower—electricity produced by flowing water—is an efficient form of renewable energy, but it often comes at a high cost to the environment and society. Now a technology inspired by beaver dams and airplanes may help eliminate these drawbacks.

Engineers with NatEl America, a Grapevine, Texas-based renewable energy company, have developed a new way to generate electricity using the dimensions of a beaver dam and the physics of fixed-wing aircraft.
