Last may @X31Andy came over to visit. Being a renewable energy geek, when I asked what he wanted to do for the day, he asked to go see some wind Turbines. By pure chance it was national wind mill open day, which gave us a crash course in 400 years of wind energy. Starting with a post mill, then a smock mill, before entering Flevopolder and visiting 3 generations of wind Turbine.
What amazed me most of tho was that the quietest of the turbines were the newest. 1/n
