What is a Lifter?
"The basic device merely consists of a lightweight (typically balsa wood) frame, to which is attached a wire and a sort of aluminum foil skirt. The photos below illustrate this. The wire is charged to approximately 30,000 volts by means of a power supply and very thin wire attached to the corona wire. The aluminum foil skirt is coneccted to ground by a thin wire as well. When the device is powered it developes downward thrust and levitates."
