After ten weeks the EMdrive is still running at NASA

a reply to: HighDesertPatriot

Good question, but we know the physics behind a shaken coke bottle. Apparently the unknown "why" is the mystery behind the propulsion, no matter the amount at this point.

I love a good mystery.

Everything once was just a dream SciFi is just a prequel for what's coming next in evolution. .

Absolutely , but we are closing the gap from centuries to decades.

I don't know ,but I just remembered something voyager one I believe encountered leaving our solar system ,was it not that the craft entered magnetic bubbles ?

If it's not working outside our atmosphere then its not going to be significant for space,but we still don't know that.

If it does work then we are well on our way to manned missions within our solar system.

I don't think massive starships with artificial gravity would work to fly a hundred years or so to another star system.

But probes would be the first steps to test this engine ,and I think this could happen very soon imo. ?

That I don't know , but one would ask how would Roger Shawyer and Guido Fetta gain such knowledge?

I've seen something very similar years ago. We had the same arguments about it then, but it was before the topic of dark matter and I don't recall anyone fronting the argument that it functioned by expelling virtual particles. And I would have sworn the scientists that time were Asian.

I think you are talking about Dr Ning Li. Who founded a company for Anti-Grav research and then 'dropped off the radar' shortly after.

Perhaps she's working on some classified project or has suffered some sort of setback?

So you're telling me they stole this invention?

I'm telling you I've seen this thing in a prior incarnation. But still very, very similar physically. And I don't recall these two guys being associated with it then.

At the time, the mechanism of operation was supposed to be some sort of momentum transfer that somehow was asymmetric, and the argument was that it could NOT be, and around and around it went.

And IIRC, the guys I remember talking with about it would have put the thing in the late 90's.

NASA Breakthrough Physics & BAE systems stuff, I suspect.

Always thought it was a little weird that they were just getting some good papers in regard to Podkletnov, Li, Mach, Shawyer and others and then (it seemed) the next day, it was all gone. No funding, no conferences and a stack of archived websites.

There is a US Physicist (who works for a Chinese University, go figure?) who has published a few papers and hosted some conferences about similar research. I have gotten out of touch, but I could reach out to him to find out what he thinks.

You science minded guys are naturally correct when you shoot what I am saying down, but you are not thinking laterally either.

Maybe this video showing quantum trapping will show the potential of magnetism I allude to.



It's just levitation here but magnetism has overcome gravity and the object is locked in space. Now scale that up to earth sized magnetic field and the potential to lift an object becomes quite big in both terms of physical size and altitude.

I vaguely recall that, also. Some kind of electrogravitic capacitance pulse drive?

How did the perfectly reasonable science of superconductors and magnets get turned into "Must See!!!UFO Levitation Technology!!"?

a reply to: GetHyped

Lol dunno. It's not my vid obviously.

I guess someone got a little excited when they saw the double levitation magnetic rail.

a reply to: markosity1973

Tipical how they use saucer shaped models. Doesn't maglev trains work on this principle?

They are running it for weeks to determine what produces the thrust. If it comes 100% from the electricity supplied, then the engine is the new future. If it is expelling some consumable propellant or ablating part of the structure away, they want to know.

100 uN @ 80W (1.25 uN/W)

The current gen Ion thruster NSTAR does 92,000 uN @ 2100 W (43 uN/W)
The current next gen Ion Thruster NEXT does 236,000 uN @ 6900W (34 uN/W)

The important detail here is ISP (specific impulse).
NSTAR = 3300~ max ISP
NEXT = 4200~ max ISP
EM Drive = infinite ISP (no fuel consumption)

ISP isn't infinite in the real world.

There is mass-energy equivalence (about 9.0 × 10^16 joules per kilogram) i.e; the energy that powers travel itself has mass and that mass is consumed in the process.

and, mass flow rate would have to be limited to the speed of light (C), too.

I get max ISP as approximately 30,633,437 s. (usual caveat: back of the envelope calculation, could be wrong).

And why does any of this really take centuries or even decades....an artificial slowness is tampering with things here, for one nanosecond I actually thought they were releasing the holds, now I know this is just as slow and plodding as ever.

Typical mainstream scientists, always looking in the opposite directions for answers, they have orders though, and years of schooling which forces EVERYONE to have a take on things that really are caveman style.

No, I've met Li, she was at UAH when I was getting my masters in physics, and I was working out at the Arsenal and MSFC on several contracts at the time.

This thing came up in some sort of document that went around. I remember a sealed metal bottle with a microwave emitter at one end, the bottle had a sort of biconical shape inside with ledges milled in, and the emitter was at the big end. The inventors were saying that the larger area caused by the steps inside the cone would result in more momentum being transferred to that side, which seemed ridiculous.

We had a lot of lunch debate with many envelopes giving their lives to sketches and math equations, and eventually we didn't hear anything else about it.

Our generations. Due to our advancement in technology and science we have been able to shrink the Gap from imagination to reality like no other generations in the past.

And why does any of this really take centuries or even decades

Not all of us get direct communications to ET?

Says the guy posting using those typical mainstream scientist creation hundreds of miles away to the world via electronic communication.

would it not be harder to dodge debris the faster we go? and at that speed even a grain of sand would cut like a laser ?

Space is not empty and is full of gamma rays, dust particles and other dangers. Even If we could travel at the speed of light we'd need a shield or we'd perish.

Look at the Large Hadron Collider- two particles colliding at near light speed creates tremendous energy; Imagine flying through space at near light speed where millions of particles collide with your ship every second. It's impossible at our level of understanding.
