Vaneless ion wind generator

Wind energy is usually extracted to make electricity by means of a Wind turbine, but that is not the only way to do it. Electricity can be extracted more directly by using the wind to pump charge from one electrode to another.

Electrostatic wind generators work by spraying water from a nozzle facing a toroidal charged electrode. This induces an opposite charge in the water and when the water flows out of the nozzle, each drop carries a small amount of charge. These water droplets are them blown by the wind, going through the center of the charged toroid without touching it. The droplets then hit a fine mesh, adding to its charge. The main advantage of this system is that it has no rapidly moving parts. The disadvantages are that it won't work in the rain, it needs a constant supply of water, its wind profile can't be reduced, it requires many small parts, the whole device has to be able to turn and it has to be well crafted to reduce corona discharge losses.
