This is awesome.

Just in the time between your email and this moment I found...

modular solar arrays
based on searching for the patent filer's name, it looks like this is the
original company http://www.solannex.com/
"Solannex has developed and patented a packaging technology that eliminates
over 50% of the costs associated with converting flexible thin film pv
semiconductors into modules"

no-thru-metal construction system, ensuring that the interior is totally
thermally isolated from the exterior

a modular wall, with different parts for support, insulation, wires, etc

and a toilet paper holder
