The link you posted above regarding ionic wind fails to account for
the effect observed in a vacuum:


There's a fairly comprehensive site on lifter theory
summarizing experimental results he

http://sudy_zhenja.tripod.com/lifter_theory/main.html

They claim:

" There is no experimental results in deep vacuum. ... All
experiments in low vacuum made in this group showed no
thrust (due to plasma formation between electrodes) as
expected. "

Extremely low forces can be produced by:
1) electron emission from heated cathode
2) interaction of accelerated electrons with walls of the
chamber
3) thrust by electromagnetic radiation.

The first two work only in small chambers. The last
produces real but unusably low force. Most contrary results
showing lifter force in a vacuum are alleged to be
unreproduceable or the result of poor vacuum.
