Question, How does it violate momentum Conservation? I have read about this engine over the last couple of days, and discussed it on other forums. My first reaction was that it was pure bull, till I researched it more. The concept seems vaild, though I am still in doubt as to its practical application. However the effect is sufficent to warrent farther research, perhapes in the future it may be more practical.

The method they use is not too complex. The engine is nothing more than a wave guide tube that has been carefully shaped for the waveform used, and the ends capped. When the waves rebound from the capped ends, some of their energy is converted into thrust in opposing directions. The differance in thrust is achieved in this manner. The wave guide is shaped so that the waves tend to cancel each other out at one end. In other words the troughs and crests line up at one end, canceling out the waves much like sound reduction technology works. The result is that less waves rebound with less force at this end of the wave guide, as energy has been used in the canceling out of other waves. Where as at the other end, the waves match up crest to crest, and impart greater energy when they rebound from this end. Thus a slight differance in thrust is achived. No laws of physics are voilated that I can see, the concept is fairly simple, I am surprised someone has not come up with it before now.
