   Depending on the set-up chosen (financial recompensation scheme, power plant, extra equipment), prices may vary. According to Practical Action, microgeneration at home which uses the latest in cost saving-technology (wiring harnesses, ready boards, cheap DIY-power plants, e.g. DIY wind turbines) the household expenditure can be extremely low-cost.

   Do it yourself or DIY-wind turbine construction has been made popular by magazines such as OtherPower and Home Power. [38] Organizations such as Practical Action have designed DIY wind turbines that can be easily built by communities in developing nations and are supplying concrete documents on how to do so. [39] [40]

5. Wind turbine - Wikipedia

   Permanent magnets for wind turbine generators contain rare-earth metals such as neodymium (Nd), praseodymium (Pr), terbium (Tb), and dysprosium (Dy). Systems that use magnetic direct drive turbines require greater amounts of rare-earth metals. Therefore, an increase in wind turbine manufacture would increase the demand for these resources.

6. Permanent magnet synchronous generator - Wikipedia

   en.wikipedia.org/wiki/Permanent_magnet...

   Some designs of wind turbines also use this generator type. In the majority of designs, the rotating assembly in the center of the generator—the rotor—contains the magnet, and the stator is the stationary armature that is electrically connected to a load. As shown in the diagram, the perpendicular component of the stator field affects the ...

7. Doubly fed electric machine - Wikipedia

   en.wikipedia.org/wiki/Doubly_fed_electric_machine

   This is useful for large variable speed wind turbines, because wind speed can change suddenly. When a gust of wind hits a wind turbine, the blades try to speed up, but a synchronous generator is locked to the speed of the power grid and cannot speed up. So large forces are developed in the hub, gearbox, and generator as the power grid pushes back.

8. Induction generator - Wikipedia

   en.wikipedia.org/wiki/Induction_generator

   A regular AC induction motor usually can be used as a generator, without any internal modifications. Because they can recover energy with relatively simple controls, induction generators are useful in applications such as mini hydro power plants, wind turbines, or in reducing high-pressure gas streams to lower pressure.

9. Vertical-axis wind turbine - Wikipedia

   en.wikipedia.org/wiki/Vertical-axis_wind_turbine

   The world's tallest vertical-axis wind turbine, in Cap-Chat, Quebec Vortexis schematic Vertical axis wind turbine offshore. A vertical-axis wind turbine (VAWT) is a type of wind turbine where the main rotor shaft is set transverse to the wind while the main components are located at the base of the turbine. This arrangement allows the generator ...
