I believe these electrostatic/capacitive
whatever systems ionise the surrounding air and
push upon it with the "asymetrical" charge.
In space there will be no matter to push against
and it won't work. :o)

There are a couple of inertial systems out there
claiming to produce thrust but AFAIK none have
passed the critical "pendulum test" yet.
