'Impossible' rocket drive works and could get to Moon in four hours
I hope this is a real breakthrough that can be developed and commercialized!

While we're very happy to have you in the Gulch and appreciate your wanting to fully engage, some things in the Gulch (e.g. voting, links in comments) are a privilege, not a right. To get you up to speed as quickly as possible, we've provided two options for earning these privileges.
4 hours would (IMO) be pushing it (I'll have to do the math), but only because the distance from the Earth to the moon is relatively close. The further one travels, the more velocity can be built... Essentially, if you were following a constant acceleration curve from, say, here to Alpha Centauri, at the point of max velocity you could make that trip much faster, but the stop at the moon would be the killer, not the ride there.
The largest issue with high velocity spaceflight (say, the 96,000 KpH you would need to average to do a 4 hour Terra-Luna run) isn't the acceleration, per se... it's the debris you would hit in space at those speeds. You would almost need to ride aft of a huge magnetic (or anti-gravitic) wave to make sure you didn't plow into something significant that would go through the ship (and the occupants)...
Sure, IF the science does pan out, and the drive is able to push something to hypersonic velocities like this, it would be a boon... but it's a very, very small baby step from that point to actually being able to have something that could eventually get us to the Kuiper belt and back in time for supper...
If they can reproduce the huge difference in energy compared to the control, it will be undeniable.
I would like to understand the experimental difficulties they describe in calculating the new isotope concentrations, using them to work out the new mass, and seeing if it went down commensurate w/ E=mc^2.
Back to topic, I worked with a fellow Air Force officer who was part of the Condon study on UFOs, and he speculated on what kind of propulsion they might use. His explanation resembled the effects shown for the system under discussion.
If it works, you'll be a hero, and rich too! If it doesn't, you'll be one of many fools, forgotten in a week or two when something interesting happens.
Working with the left hand rule of a motor and the right hand rule of a generator you use your thumb, askew to your index finger and askew to the middle finger. Hold them out in front of you and label the thumb with a M for motion and the index finger F for Magnetic Flux line and label the middle finger C for current of the induced current flow. Like a rail gun as I am sure you have heard of and being advanced for use on Navy ships it works like this. You pulse the rails that make contact with the projectile sabot that makes contact with the rail. Now for the tricky part all you have to do is figure the length of the contact rail and then you can put in the length of a electrical current pulsed square wave that would use the left hand rule for motors and right hand rule for generators and you get the gun.
Now to convert that info to travel in space. First of all remember there are magnetic flux lines from the sun and other objects in space these flux lines go way out there. Now all you would need is a means of detecting the flux lines orientation and a vessel that could create its own magnetic flux and align the vessels flux with the strongest flux felt in space and then all you would have to do is switch the vessel flux line temporarily with a quick pulse of alignment and walla you get the thumb or M movement reaction of the left hand rule of motors. Kick in the head part is.... the impedance of the vessel would have to be minimum so as to make a quick almost instantaneous switch to 90 degrees of the detected flux line you want to ride off of. That impedance if inductive reactance which is natural to any sudden change in current. So I feel it is quite feasible but we have bigger problems. Remember it would only take one of these flux lines crossed to generate in excess of 50,000 tons of force. Well think about that for a second. If you did the experiment here on earth you couldn't survive. If you did it while in orbit you'd still have the affect of the earths gravity somewhat. But wait it gets better for problems. You need to be able to communicate faster than the speed of light because you'll be going very fast and you need to be able to send out some king of radar type navigation to detect objects that get in the way so you won't run into them. So I don't mean just a little faster than the speed of light you need many factors times. Then do you realize what kind of navigation computer you'd have to have to process this info in a speed necessary to control the vessel. It gets deep. But I assure you there are not particles involve in electro magnetic impulse this way. Oh yes, there are what is commonly termed the EMP explosion which is not related to this type of discussion, that is why I think someone got off on the wrong track as to what this was trying to accomplish.
My two cents.

"If the EmDrive is still generating thrust even when the power is turned off, it strongly implies that the measured energy was thermal, and therefore indicative of a false positive reading."
"Eric W. Davis, a Senior Research Fellow at the Institute for Advanced Studies in Austin said to io9: “I noted in [the study’s] conclusion paragraphs that [Tajmar’s] apparatus was producing hundreds of micro-Newtons of thrust when it got very hot, and that his measuring instrumentation is not very accurate when the apparatus becomes hot,” Davis told io9. “He also stated that he was still recording thrust signals even after the electrical power was turned off, which is a huge key clue that his thrust measurements are all systematic artifact false positive thrust signals.” ~ http://www.extremetech.com/extreme/21...
Perpetual motion machine? When the rants about science being blinded by dogma arrive at this site, I wonder if the perpetual motion machines will be pushed too. I'm thinking of the type that move but cannot sustain a load or do any useful work.

We'll see.
A friend of mine constructed several "Q" aircraft which were powered sailplanes with silenced engines and special propellers. They were used as low altitude reconnaissance aircraft during the Vietnam war, and couldn't be heard beyond 1,000' away. Anyway, if such a propulsion system could generate enough thrust, it would be pretty quiet.
I doubt this phenomenon will ever produce enough thrust to lift a craft from the Earth's surface. Nonetheless, even at the miniscule amounts of measured thrust, a fuelless propulsion system could achieve fantastic velocities over long periods of time.
Here is a possible mechanism that could produce thrust without violating Newton's third law.
Lets assume that it is possible to use some sort of field to accelerate these particles but their lifetime is so short that they annihilate before they reach the far wall of the chamber and thus cannot impart the opposite momentum. Interesting notion but I wonder if it is crazy enough to be true.
In the interview, the guy claims that airplane versions would be quiet. My guess is that a great deal of the noise of an airplane is produced by the air flowing over the airframe. In addition, the engine has to push against the air, when it is in air, so it will make noise also. These claims undermine his credibility in my mind.
I was reading numerous articles on this, and while I am by no means a scientist this makes perfect sense to me, and in my brain I can grasp why this would work.
"The technology requires no propellent to generate thrust, which means it goes against the principles of classical mechanics, which are a set of physical laws to describe how the motion of objects should be influenced by particular forces."
The claim it has no propellant, tells me that science yet again is caught up inside their own closed minds.
What is propellant? These boneheads are in essence saying that propellant "must" then be a combination of chemicals that cause a physical reaction. Rockets are really only controlled explosions of chemicals.
EM stands for electromagnetic.
I can launch and fire massive objects propel objects across magnets. Electricity is the propellant, the motion of electrons, neutrons and protons. If E=MC^2 then I can, in my mind see how the agitation of these atomic forced could propel something.
Now if I can grasp this why is it these "peers" refuse to even contemplate this.
Because in my opinion the VAST majority of supposed science is not really science, but the closed minded nature of elitist intellectuals who want to prop themselves up as superior. To admit a mistake or lack of understanding they feel diminishes their self important status.
Only a few REAL scientists take new thinking seriously and explore it and use the REAL scientific method to determine the value, as opposed to their own closely held beliefs they they hang on to like the more religious of people to their faith.

The missing piece to this drive that makes it somewhat of an enigma is the lack of an understanding of how the phenomenon works. So far all that's happened to explain the apparent violation of the conservation of momentum is a guess that it somehow taps into "transient" particles that pop in and out of the space-time matrix. Hopefully a better explanation will be developed, even if it overturns what we currently accept as the inviolable laws of physics.
If this had any chance of being able to achieve escape velocity, the thrust would not be so subtle there was a question that it actually functioned.
