Much ado has been made about using the ZPE as a source of unlimited energy. The Casimir effect between two plates being the quintessential experiment proving the plausibility of such claims. I recall months ago that physicsweb.org reported an experiment that found that the effect could even be used to move the plates apart, not just together. Considering such experiments, one wonders if the ZPE could actually be used as an alternative energy provider. One must also wonder then, given the convervation of energy laws of the Universe, what effect our 'tapping' of said ZPE (if at all possible) would have on the Universe. Clearly the effect would be negligible at best, but still I think its interesting to consider what effect it would have. Furthermore, I am curious if there has been any theory linking the ZPE to Dark energy? If you will be so kind to indulge a philosophical whim of mine, is it possible that 'tapping' the ZPE would in turn diminish the Dark energy, and consequently hinder the Universe's current accelerating expansion? Please forgive me if this last question is too sci-fi for this forum, merely think of it as an interesting thought, if not purely in the imagination.
