You can trace back the concept of scientific biomimicry back to the times of Leonardo da Vinci, his previous flying machine designs were derived from his direct observations of wing flapping of birds. However, the aircraft designed by Leo could never take off from the ground. Now almost five hundred years later, a team of engineers working at the Tyer Wind decided that insights could be taken from hummingbirds for the design of new turbines.
The team of designers working at the Tyer Wind recently analyzed the wing movements of a hummingbird hovering in the sky. They discovered that the wings of this bird had a three dimensional figure-8 kind of pattern that had wings extending up to angles of 40 degrees from the horizontal end. This formed the base for new design of turbines. It made from carbon fiber composite material and every single wing of this turbine has 1.6 meters length and 80 degrees of motion providing the turbine with a total swept area of approx. 3.6 meter square meters. The volume of these wings is 0.6 cubic meter, it has complete mechanics inside it, along with, a very small sized magnet generator.
Tyer is yet to release the wind curve for these turbines and are waiting for further results of tests done in field. The data sheet of these turbines shows that the output of these turbines can be rated at 1kW along with a wind speed of 10m/s. At this velocity, the power consumes less than 5kW of power which grants the turbine with an efficiency of twenty percent over the previous one. Just remember, the rated output for wind velocities of small turbines is specified and you may never see the places these are located. In case the speed of wind is flowing at a regular 10m/s, you will just need to bend the trees at an angle of 45 degree angles.
