Abstract
Method and apparatus for electrostatically generating power by converting random mechanical motion into electrical energy. The apparatus includes two variable capacitors that have their capacitances varied in an alternating manner by the physical displacement of a common conductor that forms one plate in each of the capacitors. The variable capacitors are formed in a container which holds a fluid for increasing the output power of the apparatus. The fluid in combination with movable conductor also generates sufficient charge to bias the variable capacitors.
