This recalls the Biefeld-Brown Effect - see http://en.wikipedia.org/wiki/Biefeld%E2%80%93Brown_effect - and https://courses.ece.ubc.ca/474/Handouts/Good_Examples/NASA_t...

The effect creates an ion wind that transfers momentum to the surrounding air. Effectively, it's like a bladeless fan, but modern researchers have not been able to replicate the reported thrust - lifting 90lb - non-one's been able to lift more than a kilo as far as I'm aware.
