At the Cleantech Forum in San Francisco, Todd Glass of Heller Ehrman moderates a discussion, among tech execs, on the various solar technologies making a difference in the green movement.
We need to get back to freethinking and innovation that is core to our roots. Companies like Intel were founded on thoughts like the famous quote from Robert Noyce - "Don't be encumbered by the past, go out and do something wonderful."
