German engineering design firm TimberTower is revolutionizing wind power by designing wooden turbine-towers. This work allows the construction of towers of record heights and at reasonable prices.
At first glance, no one can imagine this is a revolutionary work in the wind power industry. However, looking closely inside the tower, the initial sense of doubt was quickly dispelled. The plastic "skin" outside is only effective to protect the wood against natural "enemies" like rain and sun. The wooden tower under construction currently will be about 100 m tall, allowing for a wind-power turbine of 1.5 megawatts. TimberTower is planning to sell its wooden towers to major equipment manufacturers that specialize in wind power plant constructions, TimberTower CEO Holger Giebel said in the post. This wind is not completed. Currently, the project is at an altitude of 60m, only half its design height. Outside the wooden column is covered with gray plastic.
These wooden towers have many advantages over steel towers. “Onshore steel pillars can only reach a maximum height of about 110 m because the ground area of a 110 m high tower must be about 4.2 m in diameter and that is the maximum maneuverable size. moving on the roads in Germany as well as anywhere else "- Mr. Giebel said.
The wooden towers are not like that, one can gather the materials to the construction site easily and that saves the cost of transporting materials significantly.
Currently, the company is planning to build a new tower with a height of 140 m in a project near Hanover, Giebel said. This enormous height of the tower allows it to carry a turbine - generating about 40% more electricity than normal wind poles today, while the cost is lower than 20%.
TimberTower calculated that, with this initiative, the cost per kWh of wind power is only 0.6 euros, equivalent to the cost of electricity produced by nuclear power plants, but it is an optimal solution for environmental protection. school.
Edwin Kohl, president of a pharmaceutical import company based near Saarbruecken and main investor of TimberTower, said he was interested in the TimberTower project because it was "truly a green energy source".
