  • Bearings: The Achilles Heel of Wind Turbines – Watts

    2014-8-26 · The horizontal-axis wind turbine was invented in Egypt and Greece around 300 BC. It had 8 to 10 wooden beams rigged with sails, and a rotor which turned perpendicular to the wind direction. This type of wind turbine later became popular in Portugal and Greece. Around 1200 AD, the crusaders built and developed the post-mill for milling grain.
