Has a Cleantech crash spurred the need for Bluetech innovation?

The recent CBS 60 Minutes documentary, The Cleantech Crash, was an apocryphal tale of wasted government funding and failed companies, and left one feeling sorry for a much maligned Vinod Khosla, deemed to be a prime architect behind the ‘failed cleantech revolution’. Khosla has rallied with a strong and stirring rebuttal in open letter to CBS.
