List of electrostatic generator patents

An electrostatic generator is a mechanical device that produces continuous electrical current. The knowledge of static electricity dates back to the earliest dawn of civilization but for ages it remained merely an interesting and mystifying phenomenon. Development of electrostatic machines did not begin in earnest till the 18th Century. These devices can produce a high electrical voltage at relatively low electrical currents. Electrostatic generator are of two kinds: (A) Frictional machines, and (B) Influence machines. Below is a list of electrostatic generator patents.
