A wind-driven electric generator according to the invention comprises at least two electrodes (A+, G) which generate an electrostatic field between them. One of the electrodes (A+) is formed as a particle generator for generating electrically charged particles which are conveyed by the wind through the electrostatic field. Thereby a potential difference is created between the electrodes, which potential is used to drive a through a load across the electrodes. In previously known constructions of this kind the electrodes are arranged substantially perpendicularly to the wind direction and usually to the ground surface as well. The whole of the electrode surface is then subject to maximum wind load. The wind generator according to the invention is formed in such a way that the electrode surface which is exposed to the wind is extremely small due to the fact that the second electrode (G) extends in a plane substantially parallel to the wind direction. Usually it is then also parallel to the ground and according to one embodiment the second electrode (G) is formed by the ground. The generator according to the invention can be provided with one or more spreader electrodes (A-) which together with the particle generator generate a dispersion field in which the particles, suitably in the form of finely divided water droplets (D+) are given a direction forming an angle to the wind direction so that the droplets are spread over a large wind cross section. |
