This kind of heat-protection is NOT based on conduction. It is based on RADIATION. And as Chis says, reflection can be an uni-directional effect, for visible light or for long-wave-infra-red radiations (wich "contains" lots of heat). So this kind of glasses will work as mirrors for visible light, but reflecting not light, but "heat", to the direction we orientate them, and not to the other. - Xevi Prat Thu, 12 Mar 2009 06:46:42 +0100 http://www.ecogeek.org/architecture/1093#comment-6891 These windows don't violate laws of physics or thermodynamics any more than a one-way mirror. One-way mirrors pass radiation (light) in the visible spectrum through in one direction, and not in another. In this case, heat (in the form of infra-red, and other non-visible radiation) passes through in one direction and not another. The idea behind the window is either the trapping of energy or the reflection of energy, not the generation of energy from nowhere. - Chris Tue, 06 Nov 2007 17:56:16 +0100 http://www.ecogeek.org/architecture/1093#comment-6876 Flipping the window will make no difference. If it did anything it would violate the second law of thermodynamics. There is no such thing as one way glass or a one way heat coating. Google Maxwell's Demon if you want an example. This window will actually be WORSE because it has an extra set of weather striping to leak. - Darrell Tue, 06 Nov 2007 08:49:41 +0100 http://www.ecogeek.org/architecture/1093#comment-6713 Alona....the center pane is doing the same thing (reflecting heat) at all times. It's just a matter of which direction its facing. - it spins Thu, 01 Nov 2007 06:07:16 +0100 http://www.ecogeek.org/architecture/1093#comment-6705 Wouldn't the laws of physics prohibit a window pane from reflecting heat off one side and absorbing it through the other? - alora Wed, 31 Oct 2007 19:11:21 +0100 http://www.ecogeek.org/architecture/1093#comment-6690 That's great news! It's about time someone comes up with windows that are more energy efficient. Plus, I agree they'd be easier to clean.:) Brilliant idea! I also wonder if they are prohibitively expensive though. - Neece Wed, 31 Oct 2007 08:44:57 +0100 http://www.ecogeek.org/architecture/1093#comment-6624 what about normal double glazed windows with curtins. does the same thing at less cost? - speedy Sun, 28 Oct 2007 17:13:59 +0100 http://www.ecogeek.org/architecture/1093#comment-6608 Brilliant indeed, but are they priced outside the realm of do-ability? What if they break? do they shatter into a million shards? What if I need to order a replacement, do I need to wait for a specialized window installer to put it in? Great idea. It's about time. - Carolyn Sat, 27 Oct 2007 07:05:44 +0100 http://www.ecogeek.org/architecture/1093#comment-6602 I just ordered a raft of windows, but I've got a big (110x54)south-facing window that wasn't part of the order. This is on the list. - Webster Fri, 26 Oct 2007 18:50:03 +0100 http://www.ecogeek.org/architecture/1093#comment-6595 I hve never seen windows like that before. It must be much easier to clean the windows instead of having to hang outside the building. - window Fri, 26 Oct 2007 07:17:54 +0100 http://www.ecogeek.org/architecture/1093#comment-6593 Wow, great invention. - Enrique Fri, 26 Oct 2007 05:47:40 +0100 http://www.ecogeek.org/architecture/1093#comment-6592 I've seen for years. Absolutely brilliant. Does the company operate in the UK? - weee Fri, 26 Oct 2007 05:16:42 +0100
