RavenBrick, a green technology company in Denver, has incorporated nanotechnology into a new building material for use with windows. The material [unknown at this time] is designed to let the sun’s heat into the home on cold day’s and keep it out on hot ones. Like the windows on the new Vdara hotel in Las Vegas, with the exception that these do not run on electricity or need maintenance over time and are cost effective with a target price of only $25.00 a square foot. The windows themselves tint like welder’s goggles or Transition lenses but the properties are completely different, it responds to the temperature differential between the outside and inside of the building. "Everybody has a window that either makes them too hot in the summer or too cold in the winter. This window knocks out that problem entirely and saves you money," said Alex Burney CEO of RavenBrick. There are several different ‘film’ appliqués that block different parts of the light spectrum to let in heat or block it out but the actual process of making and what kind of nanotech is being utilized is still a closely guarded secret because of patent pending, but Aerospace engineer Wil McCarthy(designer of the Raven Window Filter) came up with the idea of a smart window from a science fiction story he wrote about "programmable matter," an idea about molecules being changed with their interaction with light.
