Tha's not a fake: NASA has - at moment are still little- engines propelled by PLASMA, with the same fisic laws that STAR TREK producers gives to 'Voyager' engines. The plasma rocket engines will help the man to go in Marte in 18 months, saving 7/8 months... . I find a beautiful video on youtube where we can see how these works. I also write an article, but is in italian: it's still too hard for me, to write about technical things in english language; sorry.
