Re: EM Drive
I meant to ask you this before, why could the powersupply not being on the thrust measurement device be a problem? It's very common for engineers who are unfamiliar with a test setup to hypothesize the ridiculous, such as that the power supply being run off the balance causes some sort of spurious ...
Re: EM Drive
I have not seen Shawyers test setup, but Fettas test setup does not attach the powersupply to the thruster but brings in power from an external source. That is IMHO a flaw in the experimental setup. FYI in October 2006 Shawyer tested a resonant cavity on a rotating rig, the whole system weighing 10...

Re: EM Drive
Lastly, on the theory part: if the proper acceleration (in the device's rest frame) is not constant, then there goes another law of physics, because the setup would not be relativistically invariant. Still, you lose conservation of momentum, and who knows what comes next. I think worrying about wha...
Re: BLP news
After watching the demonstration again, I have a hard time convincing myself it isn't a fraud. Aside from the obvious things that I've detailed above, the fact that they weren't acting like this was some mysterious, high-energy source was interesting. I believe I saw a mention of soft x-rays - unle...
Re: BLP news
I'd love to be wrong.. That power density makes stuff like Woodward's thrusters almost lame. Except Mills is opposite Woodward's transparency, nearer Rossi's end. He's put out his theory (I was naive enough to go to my chem teacher at Uni at the time, wanting to bounce Mills' papers off of him), bu...
Re: em drive
http://arxiv.org/ftp/arxiv/papers/1407/1407.7772.pdf So the paper doesn't seem to be saying that his (White's) concept of a modified Alcubierre warp drive would or wouldn't work, only that the experimental test method devised by White would be incapable of discerning the spacial distortion even if ...
Re: EM Drive
Although there is massive cause for scepticism on these results, it's amusing to do some arithmetic on what it might mean if true. 5mN per kW combined with 2kW/kg, gives an acceleration of 10^-2 ms^-2. That's about 10^-3 light years per year per year. I don't think this is how it (supposedly) works...
Re: em drive
One of the annoying things for me, and why I haven't invested myself in following this more closely; is that everyone understands Shawyer's explanation for how this produces thrust cannot be correct. Ok since when was it ok to ignore something just because you believe the theory postulated by the c...
Re: BLP news
How do these people not have their heads on spikes (figuratively) yet? There's something wrong with the system if this sort of "trade secret" protected charade can go on for whole decades. While I share the skepticism of everyone here where BLP is concerned. I honestly would be very surprised if th...

Thanks, I will do that next time.Betruger wrote:Birchoff your links are shortened by forum autocorrect. You have to put them in [url] tags.
Re: em drive
Birchoff your links to the papers in the other thread are broken. My bad I originally markedup the paper names with an underline, didnt occur to me that they looked like links. I took the links from tokomac's post below and edited the markup in my post so that no one has that happen to them again. ...
Re: em drive
Is it wrong to suspect this is yet another instance of White pushing for hype way too early? Who exactly would gain from this? On a seperate note it would seem the Warp Interferrometer tests could now be officially considered dead in the water http://arxiv.org/abs/1407.7772 I doubt this has anythin...
Re: em drive
thanks for that last link. i thought for a moment there had been some real scientific revalation. but same old, by the look of it. SLACKNESS. shame. what do you mean by SLACKNESS? On whose part the skeptics or the experimenters? both. & also journalism. & NASA. eg: i can't easily find anywhere (eg:...
