Thank you. Also, Noted that the 2nd law is not violated.

Hi David
I did a search for "good-bye-second-law-of-thermodynamics"
It came up in google with this

I clicked on the link in google and it took me to the page that I
quote the first few lines of:

Good-bye second law of thermodynamics?
Good-bye second law of thermodynamics?

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)..."
Kind Regards walker
