Long podcast this week... A wealth of good stories. Could you survive on 20 liters of water a day? A UN Climate Conference in Kenya. What does the change in power in Washington mean for energy and the environment? No rain in Australia. A Woody Allen impersonator on the podcast? A virtual fence along the U.S. borders with Canada and Mexico. Electronic voting machines: Can they be trusted? Taking courses in terrorism. And last... An airplane that makes no noise. Can that be true?
