Hi David I did a search for "good-bye-second-law-of-thermodynamics"
It came up in google with this http://www.laserfocusworld.com/articles/2014/09/good-bye-second-law-of-thermodynamics.html I clicked on the link in google and it took me to the page that I quote the first few lines of: " Home <http://www.laserfocusworld.com/content/lfw/en/index.html> Good-bye second law of thermodynamics? Good-bye second law of thermodynamics? 09/02/2014 By John Wallace <http://www.laserfocusworld.com/content/lfw/en/authors/john-wallace.html> Senior Editor I was quite happy last week to post a news item about a colorless transparent luminescent solar concentrator developed at Michigan State University <http://www.laserfocusworld.com/articles/2014/08/solar-collector-is-transparent-colorless-doesn-t-block-the-view.html> (East Lansing, MI), as I have had a long-term fascination with luminescent solar concentrators. So why am I so fascinated by such devices? One reason is that at first glance they seem to violate the second law of thermodynamics <http://www.laserfocusworld.com/articles/print/volume-49/issue-06/features/chillers-and-coolers--breakthrough-of-optical-refrigeration--las.html>, which says that the entropy of any isolated system never decreases. In the field of optics, the second law sorta translates in a hand-waving way to the fact that the étendue (solid angle multiplied by beam cross-section) of a light beam can never decrease: for example, one can't focus a low-quality laser beam to a spot as small as that that can be produced by a high-quality laser beam (given the same lens used for both, with lens pupil optimally filled)..."
