Solar Power’s Tipping Point?

The San Francisco Chronicle reports on an innovation in solar technology that could revolutionize the industry:

A solar array crammed onto the top of a typical office tower could produce, at best, a tiny fraction of the electricity the building and its tenants need.

But what if the building’s windows could serve as solar panels?

Pythagoras Solar in San Mateo has developed a window laced with solar cells, a window that generates and saves electricity at the same time.

Thin horizontal rows of silicon cells embedded between dual panes of glass catch light from above. And through a trick of optics, the window blocks direct sunlight from entering the building, cutting the amount of power needed for air conditioning.

The full story is here.
