Vertical wind turbines put pressure on bearings, but one company, Enviro Energies, has a better idea: maglev or magnetic levitation of the turbine so that it will turn, not on bearings that need lubrication and servicing, but on a virtually frictionless force field of magnetism. In addition, Enviro sees its new vertical turbine as suitable for city rooftops, as its design takes even light wind currents from any direction and converts them to usable electrical power. See a Discovery Channel demonstration of how the turbines work.
