I realize I am 6 month late to the discussion but here goes... you are simply taking advantage of Newtons third law. "Every action has an equal and opposite reaction. By ejecting a comparably small quantity of material at very high speed, the resulting force in the opposite direction (up) will be big enough to lift the space craft... Air/Atmosphere will actually reduce the thrust as it will create a counteracting static pressure at the outlet/nozzle.
