Maglev High Efficiency Wind Turbine

One of the biggest drawbacks in harvesting wind power is the energy lost to friction between moving parts. Using a system of magnets to reduce friction and essentially hover the rotating part of the turbine the above design is not only more energy efficient but it also occupies far less space than a conventional spread-out wind farm. Due to their ease of movement they can also rotate and generate power at incredibly low speeds compared to conventional turbines in wind farms. (Source
