Some of the interesting ones:
Nanosolar: High-efficiency solar cells
Gridpoint: Something to do with power grid management
Plastic logic: Flexible displays
eSolar: Solar thermal power
HelioVolt: More solar cells!
SulfurCell: More solar cells!
GodTube: Christian Videos. Seriously, this one sounds like a joke, but it exists and somebody gave it $30 million.
Fisker: Electric cars.
Admittedly a rather high percentage are still web-based software of some kind. And an awfully large percentage of those remaining are related to energy.
Another interesting (if worrying) trend: I couldn't find any biotech on the list at all (there might be a few, I didn't look at everything but I checked the names for bio-sounding things).
