  In Australia on Tuesday February 13 th , 2024, over 500,000 Victorians were left without power, the authorities are blaming it solely on the collapse of several transmission towers. This claim comes from a government whose plan is to build more and bigger towers to carry green energy around the country. The reliance on green energy is part of the problem, storms and dark clouds reduce the production of electricity from solar panels and inhibit the production of power from wind turbines.   It is a strange fact that, even though this might sound like a contradiction, too much wind causes wind turbines to stop. Anything in excess of 25 m/s (90 km/hr) is dangerous for the wind turbine so it opts to shut down. When the anemometer registers wind speeds higher than 80 Kph (cut-out speed varies by turbine), it triggers the wind turbine to automatically shut off. The direct drive controller allows the machine to start at wind speeds of about 11 - 18 kilometr...

  This is the way I keep saying we should build our wind turbines, then we wouldn't be burying them as landfill after only 10-20 years. We should also use metal blades that could be recycled.     These 1000-year-old ancient Persian vertical-axis windmills, standing in the arid landscape of Nashtifan, Iran; are not just relics but are still operational. Crafted from natural materials like wood and reeds, they harness the wind's power to grind grain, a testament to sustainable engineering from a millennium ago. Their enduring design is a marvel of early technological innovation, reflecting a deep understanding of environment and resourcefulness in using renewable energy long before the industrial age. #AncientPersian #Persian #Nashtifan #landscape #archaeological #archaeologist #Museum #Ancient #Historyfacts #History #Historic #Historical                            ...
