Electromagnetic Turbine

I recently saw some designs for an electromagnetic turbine engine. I am skeptical of the design and was wondering if it is possible or feasible. The basic principle is that like a gas turbine engine it will take air and compress is but instead of mixing fuel with it and igniting the mixture, it ionizes the air a repels it out the back of the turbine engine. This is some what like a space ion thruster but i believe its different in the fact that the acceleration is achieved by compressing air and ionizing it. It is supposed to get a double kick, one from the repulsion from accelerating it with a magnetic field of the same charge as the ionized air and other from simply using the "fan" like system of the turbine. This design was NOT for a car, it was for a way of accelerating a MagLev type train. So basically would this work with no ground friction yet air resistance still present.
