So ... hope it's not a re-post, but this piece came into my attention today -
Numerical and Experimental Results for a Novel Propulsion Technology Requiring no On-Board Propellant
Nasa validates 'impossible' space drive
Full version d/l
I first read about this thing about a year ago, courtesy of EvE Russian Chat (more frequently addressed as ShitChat). I didn't bother to save the link (and frankly a bit lazy to search it now) but it was an abstract of an experiment displaying that thrust can be generated by application of sheer EM energy. No propellant whatsoever. It stroke me as somewhat of a novelty in space propulsion (in which i am in no way an expert). Again, i don't remember why exactly (the tech. details), but i had an uneasy feeling, though not being able to formulate it, that something in that thing is in discrepancies with the basic laws of conservation. So i took it to my old man, which in another life in another place majored in astrophysics. I felt mainly irritated after that talk, due to the way that is so typical of physicists, he had very little to contribute to the issue of feasibility of such a thing, while he did a lot of talking. So i forgot about the whole thing, until it was linked to me by a ShitChat buddy.
Both the results confirmed by peers, and the vague claims (along with complete absence of whatever theoretical explanations) and general feeling that no one has a clue why it works the way it works should make it a wonderful dish for tinfoilers of all casts, colours and convictions.
