Fran, An interesting perspective.
Perhaps related to a paper in my stack (which I have yet only perused)? - "Quantum Measurement Information as a key to Energy Release from Local Vacuums" - Masahiro Hotta http://arxiv.org/abs/0803.2272 (His other papers at arxiv.org/find/quant-ph/1/au:+Hotta_M/0/1/0/all/0/1) Still a contentious topic, but, hopefully, vacuum energy can be extracted. -- Lou Pagnucco Roarty, Francis X wrote: > Lou, > I have ben positing this with respect to DCE, the change in casimir > geometry and therefore the restriction of virtual particle sizes is just > such a Maxwellian demon.
