Day by day the number of vertical axis wind turbines growing. Because they are more efficient, easy to install, smaller, and most important one cheaper to build than the common wind turbine designs.

Windspiral Turbine

One of these interesting design is Windspiral turbine which is roughly 10 meters long ant 1 meter width. As the others it is also used for converting wind energy into measurable electrical energy. It has same working principle with vertical axis wind turbines. And it is remote controllable. The owner of that design can track it from computer thanks to wireless modem.

Windspiral wind turbines can produce 2 Megawatt hours per year in 5.5 meters per second average wind speed which is approximately half energy used by a regular house. One more advantage of this design is lower rotational speed. It means less noise and less loads on materials. It can be used easily in cities or gardens of houses. With some modifications it can produce more energy which is enough for a home. You can get an impression by watching following short video.
