It made dangerous amounts of heat at the high RPMs that those engines operate at. He said his former enemy was always the heat generated by two sets of veins, paddles, blades rotating at different speeds. If it's heat from wind that you want, then this is actually an elegant solution.Ībout 25 to 30 years ago I designed a brochure (I'm a graphic designer) for a start-up company headed by a former aeronautical engineer who used to specialize in aviation transmissions (I didn't even know that airplanes had transmissions). This is often done as a "dump load" in diversion battery controllers, but in this case one would just connected the alternator directly to the element and call it a day. So, it makes more sense to use the wind turbine to drive an alternator, then send the DC output directly to a water heating element. I expect the losses to be greater than those seen by a good alternator. Therefore, there would be extreme thermal losses involved in containing the heated water and especially in transferring the heated water to an end use. However, note that wind turbines generally have to be elevated for good performance. If the vessel were pressurized, then this could help minimize any cavitation in the pump. On that note, you could drive a vane pump (hydraulic) with the wind turbine sending the discharge of the pump through a pressure relief valve, and contain the whole apparatus within an insulated vessel. The same principle applied there even though it was basically a large hydraulic pump that sent the water through a restriction. I used to work at an experimental power plant that placed a large "water brake" on the output shaft as a load. Any resistance to the motion of the "paddles" contained in the vessel will transfer energy to the water to raise its temperature. Cavitation is not required, but may be unavoidable. See Joule's work in thermodynamics during the 1800's. Bill, I second (or third) the idea of "stirring" water contained in an insulated vessel for heating.
