Abstract
A three-terminal capacitor having high and low voltage electrodes coaxially aligned in a housing which serves as a ground plane includes a non-gaseous dielectric material filling the cavity of the housing. In the preferred embodiments, the dielectric is either an oil or plastic. A source of power voltage can be generated by arranging a tertiary electrode proximate to the high voltage electrode and selecting the ratio of surface areas to produce sufficient current to power an external device.
