Coincidentally, this story turned up today - about the "Mach effect"
http://nextbigfuture.com/2011/06/scaling-up-mach-effect-propulsion.html#more >From the comments - it seems nobody understands the full possibilities of the Mach effect very well, including "goat guy," who is most of the way there ... ... as to how this effect would work in practice, it would need to be based either Casimatter, or on 'phonon drag' or photon switching, being the portal for DCE... DCE or the dynamical Casimir effect can be either heating or cooling, relative to the observer in 3-space. Photon switching is the conversion of real photons to virtual, or vice-versa. Although photons are said to be "massless" there is a tiny mass-equivalent based on energy (in eV) - thus, this recent article is also relevant: http://www.technologyreview.com/blog/arxiv/26813/?p1=Blogs Jones From: Hoyt A. Stearns Jr. * * Assume there's a device that can absorb energy, whether mechanical, electrical, or thermal, but not get hot -- the energy is sent to some unspecified alternate universe let us say for the sake of argument.... For the sake of this argument, assume that such a device exists....How useful is this? [snip] Another possibility for the general identity of that next lower form of energy can be simplified as "potential energy" covers a wide range of possibilities. There are hierarchies there as well - but if a material sheds heat to another dimension, it may gain potential energy in some form [even tiny mass change]. I know your next question, but I'll let others jump in to test the water on that one... since 'anti-gravity' is a subject that generally makes me too light-headed to keep a straight face. Can you spell "Casimatter"? Jones
