TL;DR
This paper extends thermodynamic laws to quantum vacuum fluctuations, critically analyzes a proposed energy extraction device, and concludes that cyclic energy extraction from the vacuum is impossible.
Contribution
It introduces a thermodynamic framework for quantum vacuum fluctuations and provides a critical assessment of a proposed vacuum energy extraction device.
Findings
No cyclic energy can be extracted from the quantum vacuum.
Extended thermodynamic laws apply to quantum ground state fluctuations.
The proposed device for vacuum energy extraction is not feasible.
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.
