I forgot to include this one: "Photon steam engines" 'Work can be extracted from a single heat bath at the boundary between classical and quantum thermodynamics' http://cm.physics.tamu.edu/cmseminars/cm_talks/2004_04_14_Scully_M.pdf
Various conservation laws can be used to extract heat from a single bath. > Though not a direct answer, the following may be relevant: > > "Extracting Work from a Single Heat Bath via Vanishing Quantum Coherence" > http://www.sciencemag.org/content/299/5608/862.short > > "Extracting Energy from a Single Heat Bath via Vanishing > Quantum Coherence: III.
