They have been in business for over 30 years, their product SolarWall (the "transpired solar collector") is in use on buildings for the US Military, Wal-Mart, Fed Ex, Bombardier, Ford, GM, etc, they have won multiple awards and has been praised by the United States Department of Energy as "[in the] top two percent of energy related inventions." - why don't they get more coverage?!?

Thermal Paint that Generates Electricity
With the application of a Nansulate paint coating, the thermal difference between inside and outside temperatures could be used to generate electricity, in addition to saving energy through its insulating properties.
