You're confused, an ion engine is a type of rocket. The problem with this type of drive is too much thrust is claimed for the amount of energy expended. You really can propel something with photons, whether microwave or light, since photons have momentum. But it's to the tune of a newton per 300 megawatts; in other words a fiendish amount of power to get a very small amount of thrust. Our universe is perverse like that.

This "physicist" Tajmar has made all kinds of absurd unreproducible claims and experiments of making gravity wave effects with superconductors and similar. In short, a self-deluded person trying to be the next Einstein when really he's more snake-oil purveyor.
