The Impossible Propulsion Drive Is Heading to Space

The EmDrive, a hypothetical miracle propulsion system for outer space, has been sparking heated arguments for years. Now, Guido Fetta plans to settle the argument about reactionless space drives for once and for all by sending one into space to prove that it really generates thrust without exhaust.

Even if mainstream scientists say this is impossible.

Fetta is CEO of Cannae Inc, and inventor of the Cannae Drive. His creation is related to the EmDrive first demonstrated by British engineer Roger Shawyer in 2003. Both are closed systems filled with microwaves with no exhaust, yet which the inventors claim do produce thrust. There is no accepted theory of how this might work. Shawyer claims that relativistic effects produce different radiation pressures at the two ends of the drive, leading to a net force. Fetta pursues a similar idea involving Lorentz (electromagnetic) forces. NASA researchers have suggested that the drive is actually pushing against "quantum vacuum virtual plasma" of particles that shift in and out of existence.

There are many things that I don't understand about this drive. If it produces constant acceleration, then kinetic energy increases with the fourth power of time. Yet the energy supply to the drive is presumably constant w.r.t time. So where does the extra energy come from? This is the most obvious question, as it suggests the drive is tapping some unseen source of energy. Perhaps the em drive is driven by the same forces that drive cosmic inflation?

My impression is that commentators in astronomical journals underestimate the significance of this discovery if it turns out to be real. The big deal here isn't that it might allow cheaper low orbital satellites. It really would provide humanity with the keys to the universe, along with what would appear to be unlimited free energy. Without a doubt, the most significant technological discovery since paleolithic man rubbed two sticks together and created fire. It would change the nature of human existence in ways that are difficult to imagine. The newly discovered proxima planet could be reached by a human crew within a couple of decades. The solar system would be opened up to mass human colonisation.

This was being talked of under the faster that speed of light as it is creating warp of space time around the device. From what I have read this is an RF style of field that is being generated. Its simular to the megaspher shields that we have talked about for the habitat for long durations in space but at much higher energy levels.

Right now, all they are doing is seeing if it can be used to maintain a satellite's orbit against atmospheric drag in low Earth orbit. the thrust its said to produce is very weak. I think some sleight of hand may be at work here. It might be worth while to send it into space to see if it works, it would be better if they could use it to send something to Mars, rather than just maintain its orbit against atmospheric drag. After all one can always overestimate atmospheric drag and say it works. What we really need to do is to accelerate an object with the em-drive, that would once and for all prove that it works. If a satellite could go into a higher orbit using the Em-drive, that would prove it beyond question!

Topic was here at this link http://newmars.com/forums/viewtopic.php?id=7110
Impossible space engine
Plus there are others which we have put some of this design within....

The EM drive was brought up again on the John Bachelor Radio show, it seems this doesn't go away. You know what this reminds me of?
Flubber.

In the movie, a type of putty was invented, that when shaped into a ball and dropped would bounce and with each subsequent bounce the flubber ball would bounce higher gaining energy. The professor even developed a type of propulsion system using flubber balls bouncing around in a chamber. What would you suggest are the similarities and differences between say the flubber ball propelled flying car and the EM drive?
