I have always been fascinated with wind turbines. However, I only thought there was only one kind of turbine. Horizontal. To my surprise, I discovered Belgium based Gual Industrie StatoEolien Vertical-Axis Wind Turbine, which created a vertical wind turbine. Interestingly, the Company claims its vertical wind turbine is thirty percent more efficient than a horizontal turbine. Their product is able to create energy utilizing the wind streams differently than the horizontal wind turbines. In addition, it fits on top of your house.
Gual installed its prototypic product in 2004, and has two models with dimensions in meters. (A meter is a little bigger than a yard.) The G4 unit is 4 meters in diameter and 1.5 meters in height. The bigger G8 model is 8 meters in diameter and 3 meters in height.
I have been interested in wind turbines for some time since my own house sits on top of a hill. In the winter, there is so much wind that I feel like Dorothy in the Wizard of Oz when I venture outside. However, my town has a height restriction for structures.
In order to install a 10K system, Bergey, a leading manufacturer of residential horizontal wind turbines recommends that the tower should be at least 80 feet high. In addition, it recommended that a homeowner should have at least one acre of land so there is no dispute with your neighbors as to the turbine’s noise. Given height restrictions in towns today, a homeowner would have to obtain a variance and the town may deny it. In this case, Gual’s vertical solution may be the answer for many residential landowners.
Notably, Gual claims that their vertical wind turbine is not noisy. In addition, height would not be a deterrent. Judging by the dimensions provided by the Company for the G4, the turbine will only add about 5 feet to the height of your structure. If you want to see what the vertical wind turbine look like on top of a house, visit Gual’s site and download the videos. To be honest, the turbine is not the prettiest structure, and a typical homeowner may not want this turbine on their house.
