Betz's Law
Filed Under:
Albert Betz was a German physicist who first determined that the maximum amount of energy you can extract from the wind is far less than 100% - its 59.3%. If you were to try and take more energy out of the wind with a wind turbine, you would slow down the wind, creating a wall of wind in front of the turbine which would divert high energy wind around it. In the end, any energy beyond 59.3% is fool's gold - you just can't capture it. read more...
