How a Hummingbird Creates Green Energy

Tunisian start-up Tyer Wind developed a wind turbine inspired by nature, and in particular by the smallest and most efficient bird in the world, the hummingbird.

It is the only bird that can hover by flapping its wings in a figure-eight forming pattern. Tyer Wind used biomimicry principles to replicate the mechanical action of hummingbird wings.The start-up co-founder Anis Aouini invented a technology called Aouinian 3D-Kinematic, which became the fundamental part of this wind turbine.

Tyer Wind's wind turbine differs from traditions rotor-based wind turbines because instead of converting linear motion into a circular motion, it generates energy on both the upstroke and the downstroke. The design imitates the hovering of the hummingbirds, making the wind turbines blend fully into nature.

"This opens new horizons regarding the way electricity could be produced in the future. Major U.S. research centers have extensively worked on the hummingbird's aerodynamic behavior and confirmed that it is more efficient than bladed rotors” said Aouini. Another asset - and maybe the best one - is that this wind turbine is probably one of the most beautiful wind turbines designed so far.

What is your view on the coronavirus?


Siri Beerends: I really embrace the idea that viruses can teach us a lesson in modesty. It is necessary that our position as the dominant species on the planet is being challenged. I also agree that it is a mistake to think that we are becoming Gods. But unfortunately, this is actually what is happening now. Corona doesn’t teach us to be modest, it teaches us how we can -as quickly as possible- go back to business as usual: saving our capitalistic economy.
