Stupid idea: What if one could charge the particles of air with a charge and then charged parts of the planed depending on the wished for airflow.

So air is negative, surface beneath the wing negative charge, surface above the wing positive charge, etc.

That has been done (on small scale) - see https://en.wikipedia.org/wiki/Ion-propelled_aircraft

I'm not sure what the achievable efficiencies are, but I think one downside is that they can generate ozone.
