Mel and Tom talk Space X, the recent issues with a boat near the landing pad, and the deploying of parachutes for manned-capsules. They discuss Virgin Galactic and space tourism. Mel debuts a new section of the show called "Elon Speaks". They discuss China and its dirty-coal-based power grid, and Tom asks the question; are they clean cars if they are electric cars in China? Mel speaks to Sherry Boschert, author of Plug in Hybrids: The Cars That Will Re-Charge America about lifecycle analysis of vehicles. She explains how we can look at the entire life-cycle of the vehicles and find out which are the cleanest cars.
