The thrust developed by the mechanism you cite would not provide enough instantaneous force to lift anything heavier than, say, a small frog. This mechanism can work where the countervailing forces are small, like in outer space, or where gravity is otherwise cancelled out. Plus, you have not identified the sub-mechanism by which the ions would be thrust from the cathode and beyond the anode to the outside. Additionally you just assert 'air is compressed' - how?, and if you have a compression assembly wouldn't that provide some lift as well? Perhaps all the lift? I think that you are just asserting a bunch of stuctural components, like doughnut shaped anodes, and not recognizing that if they have enough power to attract ions, they might just not let go of the ions, shortcircuiting any effective lift. Overall, the idea is plausible, but the materials science we have working against the physics prevenst it from working in any instantaneous high force fashion.
