Prism Glass Windows Making a Comeback

Steve Daley writes "Prism window glass like Luxfer was big back in the 19th century, but now it seems to be making a high-tech comeback in Japan, where several companies are commercializing similar technology that gets enough natural light into factories and offices to do away with electric lighting. It's easy on the pocket and the planet."

Yes if windows could be a glass dome on the roof that captured light and distributed it to many rooms on many floors separated by a novel invention, walls --or even better, ceilings.

It really looks like a light tube with a fancy projector on the end.

Actually, it does sound like the new thing is that projector at the end of the light tube, which creates a natural window appearance on an interior wall.

The dollar is weak and the quality is different.

It's not a fair comparison if the quality of the light is important to you.

The light is way better than an el cheapo flourescent, especially if color matters to you at all. Or if spraying mercury in the room when the bulb breaks does. So plenty of people might be willing to take the penalty.

Obviously that depends somewhat on how sunny your locale is, though.
