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

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."

      Why would you have sex using a wireless camera?

    Oh, that's easy, the opposite of yellow is blue, just use blue glass!

    Next step is glass that turns transparent to visible light when it's hot, for example, a bathroom window what turns transparent when a hot woman (or a hot man) gets on the other side...

      So, for most slashdotters, this would be the same as the frosted glass they already have in their bathrooms?

      ... and the step after that is of course glasses that turn opaque when facing peril, thus allowing you to keep your cool.

    Yellow tint, ew, but as for the Vanadium, if you have a double paned window, treat the inner side of the outer pane. No leakage or exposure to Vanadium, unless you break the glass. And no exposure to H2S rain.

    If you've got heat coming through the walls, just get some old-fashioned IR reflectors -- Aluminum Foil! Put it up to reflect heat away from your walls, and maybe an old fan to blow the heat off of it. Oh, and ripple it. Your very own House Heat Sink. Overclock your house!

    That's exactly what they want you to think.

    And since you're thinking it, that means they already got you. You're compromised. We can't have you at the meetings anymore. Er, I mean, what meetings?
