That windowpane in your office will soon become valuable for more than the view. Newly developed electrochromic "smart" glass can cloud up for privacy, block the sun's rays to cool you down, or absorb them to power the place.

Why The Daily matters
It's not the end of the struggle to translate print media to a digital platform -- it's just the beginning.
Among the media elite, obits are already being written for The Daily. The content is unimaginative, they say. The tech is buggy. The numbers don't add up. And it's mostly true, but maybe they're missing the point.
