The RavenWindow from RavenBrick may be the greatest window innovation of all time. The RavenWindow is designed to let sunlight in during cold weather and block it during times of heat. What's amazing is that these designs manage to do all this without using any energy.

Windows that change their pane color to trap/absorb heat are nothing new, but no window can do what RavenBrick's RavenWindow can. All you need to do is install the window and watch it at work. I foresee a home remodeling project in the future with these innovative windows.
