Here is a recent SciNews article which gives hope that "Casimir cycling" for gain is ultimately doable:
http://www.sciencedaily.com/releases/2009/12/091210153657.htm ... indicating at least that some high-priced brain power at DoE and Argonne believe that Casimir attraction can be manipulated into repulsion. That would be the key to finding a useable asymmetry in the heat of adsorption, at this geometric level. It could be as simple as rapidly cycling an electric field, in which the nanoparticles are place with hydrogen ... "As characteristic device dimensions shrink to the nanoscale, the effects of the attractive Casimir force becomes more pronounced making very difficult to control nano-devices. This is a technological challenge that need to be addressed before the full potential of NEMS devices can be demonstrated," ... "The goal is to not only limit its attractive properties, but also to make it repulsive." -----Original Message----- From: Frank I totally agree with your points and regarding CoE, ask Vorticians to keep an open mind towards a relativistic solution as an escape .
