NASA may now have a fuel less "rocket" - hmelton - 08-02-2014 NASA has posted a report of a drive that may be producing thrust without ejecting a reaction mass. I seen several links, but here is the Popular science link.--------------------http://www.popsci.com/article/technolog ... SOC&dom=fb-------------------- It's not much thrust, but needing no reaction mass would be an incredible boost to satellites, space station and anything else that needs to do station keeping. hdm God Bless - Dartz - 08-03-2014 Saw this. TBH, I'm a little sceptically now. On mature reflection, it seems that the test rig they expected to generate thrust, did so. While the control they expected not to generate thrust, also did so. There's something suspicious about that.... which suggests to me that, while they might've found an 'effect' we won't know what that exactly is until it's taken up to space. ________________________________ --m(^0^)m-- Wot, no sig? - Labster - 08-03-2014 Actually, the recent experiments made me more skeptical than I was before -- seeing similar behavior in the control is not a good sign. It would be awesome if it works though. If it shows any more positive results in ground-based tests, it might be worth the few million dollars to test it in space. -- ∇×V - robkelk - 08-03-2014 Ion drives don't eject reaction mass, but they do eject energy. Is this another case of the same thing? -- Rob Kelk "Governments have no right to question the loyalty of those who oppose them.

These ions are made from gas stored in an on board fuel tank. The gas is usually one of the inert noble gases such as xenon hdm - robkelk - 08-06-2014 Oh, look: http://xkcd.com/1404/]today's xkcd. -- Rob Kelk "Governments have no right to question the loyalty of those who oppose them.

More groundbased tests before it goes into space, much cheaper and easier to investigate. Also in the paper they suspect that the force generated by the control was due to the sheer amount of power running it through the test rig would act like an electromagnet and have some attraction. Notably the test created a lot more thrust than the control. I am somewhat skeptical still even though a chinese team and NASA both have replicated it their findings are way off from each other so... Still worth following up on just because if it works it'd be insanly valuable.

Some discussion and links on Choas Manor - hmelton - 08-12-2014 Dr. Jerry Pournelle's Chaos Manor site has several comments and several links. http://www.jerrypournelle.com/chaosmanor/ It has several other on going topics beside the fuel less rocket so you will have to scroll slowly through the stack and look for comments by Dr. Pournelle and others that are on the Fuel less rocket. hmelton Edited to correct formatting. |
