Re: EM Drive

I haven't read past sections II A and B yet, but it sounds an awful lot like a variant on an MET so far (in as much as I think I understand how the MET is working, that is :D ). Hi, The EmDrive and the Mach-Effect Thruster operate very differently: ⋅  The EmDrive is a closed resonant cavi...

Re: Mach Effect progress

Do you know @Aceshigh if the work showing Woodwards theory emerging from HN's theory will be published in a journal? I remmeber Woodward saying something about heidi publishing in a Physics Journal but that part wasnt too clear to me. Not so sure Jim refers to this, but Heidi's last paper (about HN...

Re: EM Drive

That could be better for several reasons, mainly because the cavity is heated and quickly becomes hard to keep in resonance if the operating frequency bandwidth is too short. If keeping the microwave source tuned to the resonant load is important, the resonant load needs to be part of the tuning ne...

Re: EM Drive

I couldn't help but notice in Rodal's piece that they quote the eagle claims that this modulation generates more thrust, and that their recent simulation explains why, as well as why the dielectric produces thrust, but neither of those explanations have been published in any forum so far as I'm awa...

Re: EM Drive

The real problem with microwave oven magnetrons is that they chatter all over the spectrum. I put a spectrum analyzer on them and they're just ratty microwave sources. If you are investigating a phenomenon that requires matching frequency to a tuned cavity, you need a microwave source that stays on...

Re: EM Drive

Could someone explain to me how pushing against the virtual particles of the quantum vacuum is supposed to work, please? If an object is moving, does it carry the QV with it? I.e. do the virtual particles supposedly popping in and out of existence match its velocity? If they do, why would they? If ...

Re: EM Drive

Until just recently, it was almost universally believed that any information passing into a black hole was lost forever, and thus not conserved. A very recent article (April 2, 2015) supporting the idea that information may not be lost once it enters a black hole: Black holes don't erase informatio...

Re: EM Drive

They can't accept dollars, but can they still accept donations of equipment? What about equipment "sold" to them for $1? Could provide some RF amplifiers for example. I'll ask Paul March on NSF forums. BTW he just gave very good news there : We are now seeing why we need the PTFE or HDPE ...

Re: More Helion Energy news....

Aside your remarks about Polywell, it's interesting to note Ad Astra is the company behind VASIMR:

Re: Propellantless propulsion from plain-old Special Relativ

I guess if it goes into a peer review journal there would be some warrant for that, but you know ARXIV is about the opposite of that. It;'s a great resource but lots of people publish there because you need almost no qualifications and people don't do much in the way of reviews of the work posted t...

Re: Propellantless propulsion from plain-old Special Relativ

That's what I think also. But still, have a look at Pr. Asher Yahalom's curriculum vitae: http://www.ariel.ac.il/sites/ayahalom/ And cross-posting Dr. Rodal's comment from NSF, about the authors and the academic journal EPJ where their paper has been published: The European Physical Journal arose in...

http://www.reddit.com/r/Physics/comments/2a8s0g/i_think_i_found_a_real_math_error_in_nasas_warp/ Cross posting from the Mach Effect thread as this article pertains more to this subject than that one.

Re: Mach Effect progress

Let me know if you get a thruster with decent thrust. Would love to make a quadcopter with mlts. If the Mach Effect Thruster is proven to work as expected (repeatedly and with decent thrust), then the first devices that will be "flown" would be in orbit, because the force they will genera...

Re: Mach Effect progress

I'm curious no one has said a thing about the art work. It's not mine, but I just think it is great stuff. Did it seem over the top for either article? I'd like to stay with stuff this grabbing if it doesn't put anyone off. https://www.linkedin.com/pulse/space-sucks-other-reasons-make-your-family-f...

Re: Mach Effect progress

birchoff, this is an old refutation attempt (more of a misunderstanding actually) back in 2001. This is listed in the Woodward effect article on Wikipedia: A challenge to the mathematical foundations of Woodward's theory were raised in a paper published by the Oak Ridge National Laboratory in 2001. ...
