This is a completely scratch-built, electrostatic turbine (EST) that converts high voltage direct current (HVDC) into high speed, rotary motion. My project was inspired by the Jefimenko Corona Motor which is powered by electricity from the atmosphere:
The turbine was constructed from the following items: plastic tubes and drinking straws, nylon spacers, cardboard, sheet metal connecting and mounting hardware as well as a HVDC power source used in place of the earth's electric field. The turbine features a clear plastic housing that reduces the risk of accidental HV contact while permitting an inside view of the turbine for classroom and science fair demos. When operating the turbine in a darkened room, corona discharge produces a ghostly, blue-violet glow that illuminates the inside of the housing. A side-by-side comparison of an earlier version of the EST shows the smaller, more streamlined profile. I used simple hand tools and an electric drill for construction.
Caution:This project can produce ozone gas and should be operated in areas with adequate ventilation. Work gloves are recommended when working with sheet metal due to sharp edges. Lastly, HVDC is not always user-friendly, so act accordingly!
