All that being said, a rail gun experiment like that in a single direction might be a way to demonstrate a very measurable, albeit destructive, Mach effect.

I'm not intimately familiar with the accelerations generated in rail guns, but my guess is they're thousands or tens of thousands of gees. A UHF MET should generate millions of gees acceleration, so the railgun is not an advantage in this. So far as the lengthy fluctuation, the fluctuation is gener...

I've been wondering if Mach effects could be exploited using something like a linear accelerator design, similar to a rail gun, albeit at much lower velocities. The general idea would be that of two accelerators, one above the other running parallel, connected at both ends by a curved track. The top...

So this post from Paul March (from the new EM drive thread over at NSFF) makes me very suspicious that they may very likely be generating a transient mass fluctuation in their device, but are attributing the possible thrust generated to other effects: "Shawyer used a commercial ceramic dielectric re...

Chapters 6 and 7 are my favorite part of the book as they read like a murder mystery. Finding the solution to the >>c rotation of the electron is truly worthy of a Nobel prize all by itself. That was definitely a good read, the mental gymnastics he runs you through, leading you to question if this ...

BTW, finally snagged a copy of Woodward's book yesterday. Very illuminating! Some of the math was above my pay grade, or at least complex enough that I didn't bother digging into specifics during my first read, but the real insight for me was the breakdown of how exactly he arrived at the conclusion...

I have to wonder, since they're saying that the slotted Cannae drive and the non-slotted 'null' test article both have an internal dielectric, if they aren't inadvertently generating Mach effects and are wrongly attributing it to this whole QVF idea they're trying to float? I get that impression con...

it would be better to write: "Gravinertial flux (as it's come to be called) is the "wind" of spacetime, and matter is what makes it blow." You are absolutely correct, that was a typo on my part. Made a similar mistake a sentence later. Went ahead and edited the post to reflect that, and to clarify ...

Ron, after re-reading your article a few times (and pondering the side discussion about early expeditions across the Atlantic) the sailing analogy stuck with me. It gave me a rough idea of how to draw a parallel between exploiting Mach effects for propulsion (and energy, if the thrust is constant re...

https://www.linkedin.com/pulse/mach-effect-physics-conservation-concerns-3-important-ron-stahl Excellent article, very well done! The parallels between the idea of gravinertial flux and electromagnetic field fluxes was particularly revealing. That idea really makes me think that there may be a much...

Doing a back-of-the-envelope calculation, to achieve laminar flow (a Reynolds Number less than 2300) in, let's say a 10 ft. diameter tube at 60 deg. F, with the air moving at 760 mph, would require the air to be evacuated down to about 25 milliTorr, which is a fairly substantial vacuum, but not outs...

The EMC2FDC website perdates the present reincarnation of EMC2. I don't think KickStarter existed then, but the hope was to drum up some funding essentially like what KickStarter, GoFundMe, etc does. Its kind of a leftover. However, it does have the advantage of not having Navy strings attached, so...

What about natural Mach Effect phenomena? I've never been able to think of a natural phenomenon that would generate more than insignificant effects. You really need fantastically high internal energy and UHF to get a pronounced effect. I suppose if you had entire crystal planets being swung through...

After reading a bit more about Mach's principle and the Woodward effect, I'm wondering if there might be some relation between this and the role of "dark energy" in the expansion of the universe. Namely, could mass fluctuations happening at a cosmic scale between stars and possibly entire galaxies b...

P00024 is up (9/11/2014), $300k, ends on 4/30/2015. Looks like a repeat of P00022, though spread out over a much longer period.
