You can create lift using high voltage (at quite low current), I think it relies on the voltage charging the air molecules which are then repelled (like charges repell) this provides thrust in the oposite direction. The problem is that the thrust is very low and it is difficult to carry the weight of the batteries required. I saw a demonstration in a basketball court I think, it "flew" for just a few seconds and needed very still air, no way it would be practical outside in the wind
