Although not peer reviewed or replicated, a NASA veteran claims their Propellantless Propulsion Drive, that physics says shouldn’t work, just produced enough thrust to overcome Earth’s gravity (thedebrief.org)

Note that what the mythbusters looked at was a form of ion propulsion. The high voltage on the sharp boundary of the aluminum foil repels air molecules. If you put one of those in a vacuum (or space) it wouldn’t have any thrust.

IIRC, the MythBusters did exactly that later in the episode. Unsurprisdngly, the devices produced no thrust in a vacuum chamber.
