So this is very cool.

It's not enough to make solar a replacement for base generation, but it should definitely help with peak summer production in warm U.S. cities.
Some additional realities:
- According to NREL, Nanosolar has the most efficient printed solar cell--at 16.4 perecent.
- No mention of small scale production. They seem to be focusing on metro scale and up.
- They're currently only producing 1MW worth of cells/month. But they say it'll be easier to go from 1MW to 100MW than it was to go from zero to one. Even so, it'll probably be a while until we see real economies of scale.
