To solve problems such that a positive electrode plate needs to be covered by an insulation film, a polar plate and the insulation film are destroyed by a shock wave such as a wave to result in disabling power generation, and a water tank, an electrolyte solution, and a large torque source are necessary in order to rotate an insulator film-covered electrode plate and a cathode plate in the electrolyte solution.

An electrostatic generation apparatus obtains electrical energy by connecting charge and discharge circuits 5 and 6 with a capacitor 1 to change the capacity of the capacitor 1 by external energy. The capacitor is configured by two sets of capacitor groups each configured by a single capacitor 1 or a plurality of capacitors 1 connected in parallel, and the two sets of capacitor groups are connected in series. By alternately switching the cathodes of both capacitor groups by a change-over switch 4 utilizing a drive power of natural energy or other energy, connection of both capacitor groups is made be either one capacitor group Ca or series connection of both capacitor groups to change the synthetic capacity of capacitors.
