…Today, large generators are insulated with sulfur hexafluoride (SF6 ) gas and sealed. Other examples include the induction generator developed by J. Wimshurst, which is used in science teaching materials, and the electro-fluid dynamic power generator (EFD generator), which uses the flow of gas or liquid to carry electric charge. Until the invention of the battery in 1800, the only way to generate electricity was with electrostatic generators, such as those that generate an electric charge by rubbing a large glass ball and store it in a Leyden jar. … *Some of the terminology used to refer to "EFD generators" is listed below.
