Window company sees future clearly, shhhhhh

Soladigm not only has a clear vision of its future, but it's keeping it a secret. It believes in transparency, of a sort.

Soladigm not only has a clear vision of its future, but it's keeping it a secret. It believes in transparency, of a sort. It's very much in the window business. Literal, physical windows. The 2-year old California start-up just got another round of funding from Vinod Khosla and Sigma Partners.

Soladigm is working on switchable windows, letting solar light and heat into a building on cold days. Blocking it out on hot days. This would be a step forward for passive solar design and construction, already a popular trend in sun-blessed parts of the U.S.

Nothing on their perfunctory website about WHEN they'll bring a product to market. One website describes Soladigm as being in "stealth mode." Under Google news you get one link, one. Hell, you or I would score much higher than that.
