A company named Motorwave Limited based Hong Kong, China, have developed what may be a very promising new technology dubbed "micro-wind turbines." This new technology can "generate electricity even if wind speeds are as low as two meters per second." One benefit to these micro-wind turbines is that they are small enough to fit on any balcony or rooftop and "unlike conventional wind turbines with 50-meter-diameter rotor blades, the compact micro-wind turbines are equipped with specially designed plastic gearwheels with a rotor diameter of just 26 centimeters." Another great feature to these micro turbines is if a user chooses to generate more electricity, the user can just link the "gearwheels together" to generate the additional electricity.
Motorwave claims that the installation of these micro turbines â€œcould provide up to 40% of a small family's electric power needs by storing the turbine created energy in batteries." What is the cost? For now, a set "of 20 gearwheels currently costs about $25 dollars", however the price is expected to drop once the "turbines are mass-produced." For now, this technology will only be seen in Hong Kong. However, if the technology becomes a big hit, you might start to see it here in the U.S.
