31 May A revolutionary wind converter
In Tunisia, the Tyer Wind company develops a wind converter inspired by hummingbird.
The Hummingbird is one of the world’s most energetically-efficient flyers.
The turbine is equipped with a pair of flapping wings that are over five feet long and move in a figure-eight motion – just as a hummingbird flaps its wings while hovering.
The design allows the turbines to generate energy on both the upstroke and the down stroke.
Moreover, according Tyer Wind, those kind of wind converter would be less dangerous for real birds.
