Comments on Emdrive Electromagnetic Drive For Chinese Space Ships?
Is this technology a physical impossibility? The Chinese space program is determined to find out. (Read
the complete story)
| "This nonsense was given a cover in New-scientist magazine a while back, prompting Greg Egan to beg for readers to save the magazine from it's scientifically illiterate editors:

| "Where pragmatism meets speculation; throw some money at it and see if it flies.
A very real problem with technology has been narrow field experts that will start out with a nihilistic paradigm; IE if I don't think it will work I won't even try out the concept.
This probably will not work; it will cost very little money to find out. " (icecycle 9/30/2008 11:55:40 AM) |
| "I had previously worked on matter-antimatter (e+ & e-) collision for the creation of 511 keV gamma rays that would be used to impart momentum via reflection or absorption.(shorter wavelength = Greater momentum) For the record on our project, no known material can reflect anything above x-rays, and even then only at shallow angles. The thermal cooling required to prevent absorption method from melting your gamma collector was un-attainable. (for reasonable thrust) The amount of energy neccesary to perform any EM momentum transfer is staggering, though possible. Nuclear is much much more efficient for a space-based rocket in the current day." (jon 10/1/2008 3:25:21 PM) |
| "special relativity PERMITS the conversion of coordinates from any inertial reference frame to coordinates of any other; it never REQUIRES the use of multiple frames to explain otherwise miraculous events" (how about wait for the experiment THEN post this 10/3/2008 8:09:16 AM) |
| "Given Einstein's 2nd postulate is invalid as are Maxwell's equations - I think it's wide open nowdays. The fourth power of T for radiation pressure can result is massive forces for uncontainable materials. You want photons rather than heat anyway. I have little doubt there is a viable solution that will be found." (Andrew 8/20/2009 4:52:20 PM) |
