Anonymous Coward writes: "Engineers at the University of Hong Kong and a private renewable energy company have developed a new micro wind turbine that can generate electricity even if wind speeds are as low as two meters per second. Lucien Gambarota , the main inventor of the technology, says this is its advantage over conventional small wind turbines, which only work about 40 percent of the time because of low wind speed. "We never stop this machine and they never stop because there is always one meter per second wind — 365 days, 24 hours a day, they keep working," said Gambarota. "They deliver different levels of energy because the wind changes but these turbines they keep moving, they keep spinning." More: http://www.energyhack.com/"
