The NewWind R & D startup company has completely redesigned wind turbine. Their aim was to create an aesthetic and quiet structure. The "Wind Tree" trunk and its branches are made of steel and with 64 aeroleafs on it. The Wind Tree is 10 meters high and 8 meters wide. The leaves already start from a small breeze (2m / sec wind speed) and generate electricity. The conical turbines rotating around their own vertical axis are very silent, but they only give a slight buzzing sound like real leaves. The advantage of wood is that it is durable (25 years) and easily integrated into urban environments.
