Vinay Gupta works on sustainable technology. Specifically he has been working on the Hexayurt, low cost emergency shelters. Vinay is my hero because he synthesises sustainability in a way I have never heard anyone else do. In this video Vinay talks about some of the work he has done recently (January 2009) with Akvo. He talks specifically about how to pool research together into bundles and get different organisations to collaborate on this.
