Re: em drive

not all of us have access to Jim's email list. Could you please summarize what Paul wrote? X: “What puzzles me is the fact that with no dielectric, the tapered cavity produced no thrust, whereas it should have (according to Shawyer & the Chinese).” When did they do a test with a tapered cavity ...

Re: EM Drive

Also sounds like they were running at high vacuum. Turbopumps, outgassing for a couple of days ... I'll read in more detail. This part is a bit suspect. the NTRS Abstract claims they didnt test at high vacuum. The paper describes how they tested at high vacuum. Then the "Summary and Forward Wo...

Re: EM Drive

Tom - I sure would be interested in following your progress should you decide to make one of these drives. I bet I'm not alone in my interest. Much better if you do it than some anonymous laboratory that none of us know except by reputation. You we could believe, and if it is a conspiracy then you c...

Re: em drive

Another type of interesting "exotic" matter would be the antimatter according to Feynman, PT-symmetric. It is enantiomorphic due to the P-symmetry. The T-symmetry implies negative energy, hence negative mass. It would "fall up" above Earth. But we never observed it. We couldn't,...

Re: em drive

they would be accelerated in the opposite direction than positive mass particles by a powerful field

Why? They have opposite charges and opposite mass, hence the same momentum.

Re: em drive

Not to be defending any theory, but AIUI virtual particles pop out as particle/antiparticle pairs that quickly annihilate each other. If it should be the case that the antiparticle produces antigravity or "antimass" (how could that be?) then EEP would be satisfied even when the particle ha...

Re: em drive

Now that was totally worthless. Popular mech. just repeating stuff bloggers posted days ago based on the misleading summary abstract. They should have named it the "Null - in virtual plasma theory - device" then when it caused measured thrust, readers might realize that it was the - virtua...

Re: EM Drive

Carroll's final point – that the researchers measured thrust not only when the drive was configured to produce it, but also when set up to do nothing at all – may be the most important takeaway of all. It's a point Mika McKinnon expands upon in her explanation below. It's funny that everyone I've r...

Re: EM Drive

I read the abstract linked in the OP on some post either here or on NSF. Is there a complete report on the experiment by White, et.al available somewhere? And by the way, microwave oven frequency is chosen at the water line, so the microwave energy will excite the water in the food. Is the frequency...

Re: em drive

Glad someone has read Gerry and Jeff's preprint. I sent the link to Sonny White & Paul March, but haven't yet read it myself. It seems either Gerry & Jeff have misinterpreted what White's testing with his test articles or they've provided a useful analysis of the "null hypothesis"...

Re: SpaceX News

And SpaceX had scheduled to web cast the launch today, after no web cast yesterday. They Scrubbed before the web cast was scheduled to start. It looked like the weather got really bad if the photo of the water spout just off shore was an indication. They are now looking at Tuesday for the next launc...

Re: Thermionic Converter Designer

So unless I use compressed natural gas it is going to cost more to operate than charging my batteries? I've never checked my charger efficiency but I thought it was pretty good. And I'm still thinking about the motor controller. You did mention that the output from the thermionic device could be con...

Re: Thermionic Converter Designer

Scott - Great reference information for a "How To" book. An example "How To" that would be of interest is converting my electric golf cart. (I use it as local run-about transportation.) The golf cart uses four expensive 12 volt deep cycle batteries which must be recharged about e...

Re: LENR Is Real

Aero,The title of the thread is "LENR Is Real" in case you hadn't noticed. Rossi has the best LENR results so why exclude him? Because Rossi has his own 400+ page threads. Most of it bashing or loving him. We don't need more and the OP was not about Rossi or Ecat. Just give it a rest and ...
