For further exercises in cooling possibilities here is some design
software offered free for download by the Russian mfr
Kryotherm.  They claim much higher delta-T of 45C for a portable
freezer they make, and roughly 70C for their raw
modules.  <http://www.kryothermusa.com/Software%20Kryotherm.htm>
The software allows you to design finished devices with specified
dimensions, heat loads, insulation characteristics etc. using their
various modules.  It might be able to give by analogy a good clue
what would be the result of doubling the insulation on an existing
cooler, too.  Are the Russian modules more capable or is it the mfr's
choice of insulation thickness?  Either way, here's hope for cracking
the 40F barrier.
