ducted wind turbine advantages and disadvantages

One of the main disadvantages of wind turbines is the noise pollution they generate. Now, if you stick this on the front of a typical Cessna 172, say, and throw a crosswind at it (which, if you think of takeoffs and landings, which since they must be in a certain direction, having a crosswind is actually quite likely) imagine the yawing moments that would be induced by the propeller (proportional to the static thrust) -- even before the aircraft got off the ground and before you have a lot of control authority to counteract it! Often local residents are concerned about solar farm development because they consider these projects to be unsightly and often the land needs to be cleared. Its main advantage is that it can operate in a wide range of winds and generate a higher power per unit of rotor area. So, while deciding to buy the device, make sure you compare the advantages and disadvantages . And the power from wind energy projects is sold at a fixed price over a long period (often 20 years), and its fuel source is free. The electricity produced at onshore utility-scale wind farms is some of the most economical. Of course I can see how an improperly implemented duct could really kill efficiency (creating more interference and turbulence), but what about a well designed one? Dallas Lloyd.
