A "SMART wind turbine," that converts the energy of weak breezes into electricity may soon be rolled out in Shanghai, following a successful trial.
Local authorities are looking for partners to get the invention by 42-year-old doctorate holder Zhang Yunlong into operation in the city.
Zhang's device was recently successfully tested on the roof of the Ministry of Science and Technology in Beijing.
"Some companies have already expressed an interest," Zhang told Shanghai Daily yesterday. The technology is mature enough for large-scale production, he added.
Zhang began his research three years ago after learning that traditional wind turbines were unable to exploit the energy of weak breezes.
Once wind speed drops below 4.5 meters per second, traditional turbines stop working. But Zhang's invention can still generate power when the wind speed is barely 2 meters per second.
According to tests, the generating capacity of Zhang's machine is seven times that of traditional turbines. And as these machines are small, they can be sited on buildings.
"Our technology is leading all over the world," said Zhang, who has more than 60 patents.
The turbine can be used in areas where the wind resources are poor, such as Shanghai.
Currently, Zhang's other wind turbine products are widely used in inner parts of the country, including the Xinjiang Uygur Autonomous Region and Qinghai Province, as well as foreign countries like Thailand, Pakistan, India, Germany and Russia.
Zhang said he hoped to help turn Shanghai into an environmentally friendly city.
