Electric Car Road Trips (starts 3:42): We go on a road trip with How on Earth’s Shelley Schlender to see how all-electric vehicles are exceeding “range anxiety” by driving coast to coast, all on electricity. Along the way we talk with Boulder Nissan’s Nigel Zeid about regional plans to help more drivers “plug in” and with Hunter Lovins, head of Natural Capitalism Solutions.
Renewable Energy Nation (starts 11:53): Joel Parker talks live with NOAA scientist Alexander MacDonald and Christopher Clack, a mathematician at the University of Colorado-Boulder. They have developed a model that demonstrates how the entire U.S. can run on solar and wind power–with existing technologies, with no batteries, and at lower cost than today’s prices–within 15 years. For more information, see this video and these animations of:

Pluto Flyby (start time 1:00): Joel Parker discusses the New Horizons mission from the command center live!
An educator and perfomer, Len Barron first developed a piece about Einsteina and Bohr as a one man show, but then decided to evolve the project by enlist the help of 8 grandmothers to tell the story with their own added pizazz. Not only was lively performance produced, but a process and experience was shared. This process was captured by documentary film maker Robin Truesdale in a film coming to the Dairy Center this weekend entitled A Beautiful Equation. Both Robin and Len have joined us today in the studio to tell us more about the film, the process, the scientists and the grandmothers.
