A new type of wind power generator that can operate in low winds is one of the star attractions at the Third Asian Wind Energy Exhibition being held here this week.
A breeze of just over 5 kms an hour is sufficient to start the machine, which means it can operate for many more hours than traditional wind turbines, said Zeng Zhiyong, president of the Zhongke Hengyuan Energy Technology which developed the turbine with the help of the Chinese Academy of Sciences in Guangzhou.
It will be particularly helpful to people living in remote areas out of reach of existing power grids. Statistics show there are still more than 70 million people in China living without electricity.
Li Guokun, chief scientist for the turbine project, said government tests show the new technology can produce 20 percent more electricity than traditional wind turbines.
Zhongke Hengyuan is currently planning to manufacture the turbines which can be made to produce from 300 watts to 20 kilowatts.
The 3rd Asian Wind Energy Exhibition & Conference runs from June 28-30 at the China World Trade Center in Beijing.
