Thermodynamic properties of the quantum vacuum
arXiv:hep-th/0104127
Abstract
An extension of the fundamental laws of thermodynamics and of the concept of entropy to the ground state fluctuations of the quantum fields is studied and some new results are found. At the end a device to extract energy from the vacuum recently proposed by an author is critically analyzed. It is found that no energy can be extracted cyclically from the vacuum.
