Evacuated Tube Insulation
One of the genius elements to the evacuated tube design, used in solar thermal heat collection, is that the pipes exposed to the sun, never lose heat. That’s because the vacuum around the metal pipe has infinite R-value.
Geothermal Piles
Foundation piles require rebar connections to the building itself. Why not channel fluid through those piles to act as a free geothermal well installation?
