Ion Propelled Model Aircraft

This is one of the most unusual aircraft ever, it has no propeller, no
jets, no helicopter rotors, no wings, in fact it has no moving parts
at all. It needs no runway, takes off vertically, and will fly in any
direction like a helicopter. This 2 foot diameter model takes to the
air completely unsupported and flies on pure electricity. Lift is
produced when a negative charge from the emitter changes surrounding
air particles into ions, the ions rush toward the positively charged
grid, causing a downflow of air, keeping the aircraft aloft. It can be
built in almost any shape, it doesn't matter, but round models are the
most easily maneuverable.
