Smart Glass Blocks Infrared - But Only When It's Hot

Posted by michael on from the light-reading dept.

klevin writes "New Scientist has an article about a new way of making sheets of glass so they block infrared energy at temperatures above 29C (84.2F). Just so long as it doesn't have to get that hot on both sides of the glass. My AC comes on way before 84F. I suppose that with double or triple paned glass, you'd only treat the exterior pane."

    That's the first time I've ever seen a moderation request mod'd as funny.

    Things have been going to hell in the 3 months since I last had any mod points, and I'm starting to wonder: why haven't I had any mod points for 3 months? My Karma's 'Excellent', and has been all along. I meta moderate regularly. When I moderate, I do so conscientiously. I used to get mod points about every 2-3 weeks. What is going on?
