Dr. Feynman predicted it to be theoretically possible to generate electric energy from an electric field. For realizing his predict, a new electrostatic generating method was proposed by the author that uses Asymmetric electrostatic force as the driving force of a charge carrier for the generator. Therefore this generator was named the electric field driven generator. After experimenting with many models using pendulum-type equipment, rotation-type equipment was tried. This experimental equipment produced electricity continuously when the applied voltage to the high voltage electrode was higher than 5.8 kV. This result was estimated by a simulation, and the measured collection currents for different high voltages almost agreed with the simulated collection current. Therefore the theory of the electric field driven generator was confirmed, and Feynman's dream has become reality.
