[Robotgroup] A real NAAC for Cooling. WAS: ...HVAC and Solar Energy

Tue May 20 11:21:12 PDT 2008

   I brought up the electroroof idea because I new I would never have time to get around to the R&D and patent part myself but it is something that does need to happen to help save the planet. At one time I was looking at AAC after pulling an old fridge out of an RV and seeing the possability of turning (free)hot into (free)cold, but after someone suggested I watch the movie "Masquito Coast" the idea lost steam as I had just assumed the technology would be banned from general use. Maybe with a bunch of creative thinkers out there it could be made safe for the general public.
