The skies will get a bit safer for birds with the wind turbine, which will use no blades at all.
The turbine will capture up to 80 percent of the wind's kinetic energy (current turbines only capture about 30 percent). Instead of spinning blades, the wind will be harnessed by a sail that will move in a non-rotational back and forth motion. The motion will then be converted to a hydraulic pressure that can either be stored or instantly converted to electricity via a hydraulic motor and a generator.
The turbine will also be inexpensive, costing about half as much to manufacture as current turbines.
