Electrostatic generator/motor electrode assembly designs are provided that both minimize the rotor drag forces and increase the power output relative to older designs. In one of the new designs, both the rotor and the stator electrodes are encapsulated in a dielectric that forms smooth surface discs or cylinders that result in minimal fluid drag losses on the rotors and also increases the voltage-breakdown potentials between the rotor and stator elements. In the second of the new designs, the disc or cylinder geometry is maintained for both rotor and stator but the rotor has no embedded electrodes. Instead it is made up of an assembly of dielectric elements that alternate between a high dielectric constant and a low dielectric constant forming a smooth surface disc of surface.
