Japanese researchers have developed a low-noise wind power system that can adapt to changes in wind direction while rotating.TOKYO, Japan 2002-04-05 [SolarAccess.com] Kazuichi Seki, a team member and professor of a Tokai University science and technology research center in Kanagawa Prefecture, said similar research on the development of such windmill-shaped generators has been done abroad but that this is the first time such a system has been put to practical use. It is hoped that the new generator, which is small and makes much less noise and vibration than conventional, propeller-shaped ones, could be set up on rooftops and walls and popularize the use of wind power in urban areas. The pilot generator, which is 1 to 2 meters high, has three to five blades parallel to each other around its rotating axis. Several generators could possibly cover the power consumption of an entire household. The new system is also envisioned to serve as supplementary power for street lamps and public facilities and for power generation on remote islands and at sea, according to the team. Machine maker IMEX Co., based in Innoshima, Hiroshima Prefecture, will handle production and sales, and is hoping to sell it for about ¥2 million (US$15,000).
