Bill Nye

Arnold Schwarzenegger is betting on green. He wants to roll California's greenhouse gas emissions back to their 1990 levels, and he's promising Californians that their lifestyles - and their pocketbooks- won't feel the pinch. But is Schwarzenegger gambling with his state's economy? With help from eco-celebrities like Ed Begley, Jr. and Bill Nye 'The Science Guy,' NOVA examines California's aggressive pursuit of a sustainable energy future. From San Francisco's Luscious Garage, where mechanics create custom plug-in hybrids for customers like Google, to the Tehachapi Valley, where thousands of wind turbines are spinning out electricity, NOVA visits the places where green energy is already becoming a reality. Yet some critics fear that, as the nation struggles through an economic meltdown, the state's new policies are inviting dire consequences. Will California be a role model for the rest of the country or a cautionary tale?

Bill Nye goes planet-gazing and takes a serious look at Jupiter's features, Earth's elliptical orbit, and the distances between planets. Cool home demo shows how to make Mars soil.

'When the Atlantis team is given two weeks of vacation leave, Dr. Rodney McKay reluctantly accepts an invitation by his former rival, Malcolm Tunney, to attend a scientific demonstration that he claims will be the solution to global warming. Feeling bold, he asks Dr. Jennifer Keller to accompany him and she accepts. Upon reaching Earth, they are flown, by private lear jet, to a top secret facility in the middle of a desert.Once there, McKay is shocked by Tunney's brazen claims that he's invented a device that can cool the Earth by venting excess heat from our space/time into another space/time - an idea McKay had already pursued two years earlier. Despite Rodney's mounting concerns over its safety, Tunney activates his new technology, dropping the heat contained inside the facility by 10 degrees. But when the device reaches this goal and will not disengage, McKay realizes he has to work fast or every one trapped inside the premises will freeze to death within the hour.'
