If vaporized, no pollution problems should occur as the particles that condense out will be very small. I wonder if it is possible to develope a kind of cross between these reaction engines and ion engines. I have in mind some kind of accelerator that induces currents in a dense plasma, accelerating the particles in the plasma collectively. This may give much higher thrust than ordinary ion engines. -------
