Microbelt: An Extremely Efficient Palm Sized Wind Turbine
A tiny wind turbine is 10 times more effective in generating wind energy than other turbines its size.
Humdinger, a Hawaii based startup, has developed a small wind turbine called Microbelt that is supposedly 10 times more efficient at generating wind energy than other systems of the same size. The palm sized Microbelt uses an aeroelastic flutter and vibration of a membrane instead of a turbine to generate power. The device is inexpensive and the company aims to use it for powering building monitoring and transit monitoring sensors, replacing the need for expensive batteries.
