Production and use of plants that produce electricity from wind power has been growing steadily. This fact rejoice and steelmakers. TimberTower Hanover has a new idea: to build a windmill made of wood.

Wooden towers with propellers already have passed technical inspection; 2011 set a prototype of such a windmill, and until mid-September will be completed and a tower 100 meters high. Experts from TimeberTowera mention that wood has many advantages. For example, wood can be built much higher than the towers of steel or concrete. On location 100 meter tower construction progresses – came up to the middle, that is the height of 60 meters. The design looks extremely inconspicuous; light gray in color and there is no indication that it is made of wood. “Color is such because we have wood surface finished taping a special plastic compound that protects the tower from the storm,” says Holger Giebel, Managing Director of TimberTower.

“What we see here,” says Gibel, “the construction structure with which the tower mounted. This means that the tower will later carry only the outer plates, but we worked on for we need a skeleton of the construction, and that this language is in the middle. “The next part of the structure is located next to the tower. The next day, a huge crane will pick it up and set on top of the existing structure. There will then be fixed and covered with slabs of spruce. The tower will be 100 meters high, and in addition to 1.5 MW generator and rotor, all its components will be made of wood.

Wood as a construction material has many advantages, says Holger Giebel: “Steel towers can not be higher than 110 meters. If we want them to be higher, we should first make a stand that are higher than 4 meters and 20 centimeters. And in turn it could pass under the overpass on German highways. “The second is the case with the towers of wood, which is completely assembled on the spot. Transportation of certain parts of the roads is much lighter than the transport of steel parts. For the planned construction of a wooden tower will be 140 meters high – in Nienburg next to Hanover.

This giant will produce 30 to 40 percent more electricity than other towers, and its construction cost 10 to 20 percent less than the construction of steel towers. The goal is to get a current price of five cents per kilowatt hour – which is almost as favorably as the current produced by the nuclear power plant.
