Gigantic picture windows are awesome in that they give you a crystal clear view into whatever is outside your house, be it the majestic great outdoors or a view of the city skyline. The problem is that they're woefully inefficient, leaking heat out like it's nobody's business. What's one to do?

Well, one solution is to get windows that actually pump out their own heat. That's what this Thermique Heated Glass does. It all sounds brilliant until you realize that it'll take a bunch of energy to heat that glass in the first place. Won't that cancel out the benefits? The company claims that you can turn down the heat inside, making it more efficient, but I'm skeptical. But hey, if you're looking to install gigantic windows, it's worth investigating.
