Has a Cleantech crash spurred the need for Bluetech innovation?

On January 20, 2014, in Blog, Cleantech News, by Paul O`Callaghan

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. Cleantech, (if narrowly […]

 

Water Pricing is Not the Roadblock to Water Innovation

On August 26, 2013, in Blog, by Paul O`Callaghan

There is a commonly held view among industry observers that “water is undervalued” and “water is underpriced”.
