Legendary interviewer Patt Morrison ran a two-hour broadcast from TED today, pulling in a raft of TED speakers and TEDsters, including two of the 2009 TED Prize winners. In four segments, she asked some amazing questions and started up some cross-pollinating discussions: Shai Agassi and Ray Anderson discussing the green revolution; Alex Tabarrok and Robin Williams on economics (Alex’s specialty) and jokes (Robin’s); Nicholas Negroponte and Yves Behar (shown above during their interview) on design with a mission and the next $100 laptop; and the TED Prize, with Jill Tarter of the SETI Institute and Sylvia Earle, oceanographer.

The broadcast is available as a podcast right here — look for the February 6 show.
