Vaneless Ion
This concept requires no moving parts. Rather, the device is in appearance similar to a fence that allows the wind to pass through it. By introducing water mist with small differing charges and allowing the wind to carry the charge between electrodes, electrical power can be produced, potentially on a large scale. It is similar in operational principal with Lord Kelvin’s Thunderstorm where two bodies of water with small charge difference can create high voltage current by using the force of gravity. The vaneless ion generator uses the wind to move the water rather than gravity.
Two prototypes were patented by Alvin Marks in the late 1970’s
