Revolutionary urban wind turbines

(Nanowerk News) The Rotterdam based research and development company De Archimedes reveals that it has developed a totally new generation of wind turbines for domestic use.
This wind turbine with a diameter of only five feet will gain much more energy out of the wind than current generation wind turbines. Additionally this so-called Liam F1 Urban Wind Turbine hardly produces sound because of its remarkable design.
The turbine will be presented to the press and people coming from over 40 countries on Tuesday.

The Liam F1 generates an average of 1,500 kilowatt-hour of energy at a wind-speed of 5m/s, which resembles half of the power consumption of a common household. In combination with solar-panels on the roof, a household could be totally self-supporting for its own energy needs.
Engineer Richard Ruijtenbeek from The Archimedes explains that “when there is wind you use the energy produced by the wind turbine, when the sun is shining you use the solar cells to produce the energy.”
At present there are very few wind turbines in use for generating energy in households. One of the reasons for this is that the yield from current generation wind turbines is very low (average of 25 percent), and that the blades produce too much noise. This is where the inventor of the Archimedes wind turbine, Marinus Mieremet, has adjusted the design. By combining the form of the Nautilus shell, the theoretics of Archimedes and his own mathematics, he created a new turbine that hardly has any resistance and has resulted in a design that is virtually soundless.
Because of its screw-form, the Liam will automatically aim to the optimal position of the wind, just like a pennant and will therefore have a maximum yield. According to Mieremet the yield is 80 percent of the maximum that is theoretically feasible. The Liam has been tested over 50 times because initially the developers couldn’t believe the results they saw.
Although the revealing of the method and unveiling of the wind turbine will take place today, the company has already sold 7,000 turbines in 14 countries. The interest is so big that the company has started developing relatively small turbines for use on boats, on lampposts and in water.
