An optical induction generator is designed and tested to determine the feasibility of using radiometric forces for renewable energy applications. Through modifications with electromagnetic induction components Crooke's radiometer is transformed into an electric generator. Initial designs allow for the variation in the orientation and numbers of magnetic poles as well as the characteristics of the armature (number of turns, wire gauge, location). Prototype devices are analyzed to obtain proof-of-concept. Verification is achieved by real time variation of incident electromagnetic energy directly corresponding to angular frequency of the generator and the characteristics of the produced EMF waveform. I-V characteristic curves illustrate the generator performance. Radiometric generators with two and four magnetic poles are shown to produce alternating current (AC) signals, on the order of millivolts, which vary linearly in both amplitude and frequency in respect to the rotational frequency of the radiometric generators.
