Ray Pierrehumbert thought this notion sounded interesting, a while back at RC; at the time all I'd seen and all he'd seen was an IEEE abstract. I mentioned it at RC quite a while ago, and haven't seen anything more about it.
The IEEE article seemed to be thinking about big infrared lasers (yes, I think they'd have to be bicycle/hydro/solar/wind powered to make a net improvement -- you don't want to generate any net excess heat to power such a device!) http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=1392156 Ray's inline replies in these comments: http://www.realclimate.org/?comments_popup=307#comment-14306 http://www.realclimate.org/?comments_popup=307#comment-14322 At the rate at which light-emitting diodes are improving, it might soon be possible to make rooftops not just white, but actively narrowband emitters, to lose heat in one of the infrared windows. I was hoping some astronomer would start looking in those bands -- maybe it would be a way to locate life elsewhere. Has anyone reported an exoplanet with very narrowband IR signature? Maybe we could be the first ... --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups Global Change ("globalchange") newsgroup.
