Rotterdam, The Netherlands: The Rotterdam based research and development company “The Archimedes” revealed what it calls a totally new, more efficient and nearly silent generation of wind turbines for domestic use.
At present, the company argues, there are very few wind turbines in use for generating energy in households, partly because of the low yield from current generation wind turbines (average of 25 percent), and because of noise. The Liam F1 claims average output 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 Europe. In combination with solar-panels on the roof, a household could be totally self-supporting for its own energy needs, the company says.
“Generally speaking, there is a difference in pressure in front and behind of the rotor blades of a windmill,” said inventor Marinus Mieremet. “However, this is not the case with the Liam F1. The difference in pressure is created by the spatial figure in the spiral blade. This results in a much better performance. Even when the wind is blowing at an angle of 60 degrees into the rotor, it will start to spin. We do not require expensive software – because of its conical shape, the wind turbine yaws itself automatically into the optimal wind direction. Just like a wind vane. And because the wind turbine encounters minimal resistance, he is virtually silent.”
