Static electricity is high voltage (HV) at low current. That unexpected ZAP! occurring when you walk across a carpet and touch a metal object demonstrates HV conduction by ionized air particles. Ion wind turbines use electrostatic forces acting between these particles to produce mechanical movement.
I decided to go green by making this desk-top project from mostly dollar-store hardware; re-purposed plastic, cardboard and aluminum disposables from my kitchen recycling bin as well as some curbside junk from the neighbors next door. The turbine uses foil electrodes that encircle a plastic, tubular rotor. Each electrode has a sharp edge that sprays a stream of positive or negative ions on the rotor's surface. When these electrodes are arranged so they alternate in polarity around the rotor, each electrode repels a rotor segment carrying the same charge and simultaneously attracts that rotor segment carrying charges deposited by the preceding electrode.
Many sources of static electricity --from old CRT screens that "crackle and pop" when powered up, to room air ionizers -- will spin a reasonably well constructed turbine. You can view an enhanced version, constructed from better components and featured on this page w/the basic version, in operation here:
