This is better I think: > A vaneless ion wind generator or power fence is a device that generates electrical energy by using the wind to move charged particles across an electric field. Ion wind generators are not commercially available, though working prototypes and proofs of concept have been created. https://en.wikipedia.org/wiki/Vaneless_ion_wind_generator https://en.wikipedia.org/wiki/Vaneless_ion_wind_generator
