[unknow force]

Magnetohidrodynamic (MHD), what a name!!!! , what is the stage of this concept in the nowdays technology????, i mean, there are an MHD generator funtional in the world???, about the mhd propulsion all i know is the japanese experiment in an small ship, an the red october hunt movie , i remember reading an interesting concept in military propulsion, it used an high temperature steam jet in an helium chamber,but that experiment is reaaaaaaly old also i remember the hipotethical potasium use in the high temperature turbine gases inducing an plasma and control it with magnetic fields, so there are proyects in propulsion-generation involving MHD??????

Other than that I think it's a lot of science fiction.
