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.

Should men be able to give birth to children?


Koert van Mensvoort: Is the artificial womb frankenstein-like symbol of (male) engineers trying to steal the magical womb from women? Or… is it a feminist project and needed to reach through equality between the sexes? I personally lean towards the latter. To me it feels like progress if a girl can tell a guy to carry the womb for a change.
