Claim:
1. A plasma motor for extracting a positive ion flow, said plasma motor comprising: a single ionization stage configured to generate eleotrons by an ionizable electronegative gas introduced into the ionization stage; a filtering stage connected to the ionization stale; and an extraction stage connected to the filtering stage and including (i) a first device for extracting a negative on flow, wherein the first device is positively polarized to accelerate a negative ion flow, and (ii) a second device for extracting a positive ion flow, wherein the second device is negatively polarized to accelerate the positive ion flow, wherein the positive ion flow and the negative ion flow have a same amplitude thereby ensuring an electrical neutrality of the motor; and the filtering stage comprises a third device for filtering the electrons, which are freed in the ionization stage, during ionization of the electronegative gas.
