This TED talk from 2011 is even more valid now as we usher in a new year and look to rethink how we power the planet. Joe Jordan worked at NASA Ames Research Center and the SETI Institute for more than 20 years, serving on various projects, including flying observatories for infrared astronomy, Hubble Space Telescope design, studies of stratospheric ozone depletion and global climate change, the search for planets around distant stars, image analysis from the first Mars rover, and investigations of Saturn’s rings and the atmosphere of its moon Titan. In the last few years he’s been teaching renewable energy at Cabrillo College and San Jose State University. He leads “physics-in-nature” hikes and astronomy/stargazing evenings for various organizations or events in this area and elsewhere. He’s on the Board of Directors of Ecology Action, and long ago helped steer them in the direction of their now primary work on modernizing energy infrastructure. He originated the very first public-facility solar-energy projects in Santa Cruz, including the large-scale deployment of solar-energy systems on several of our schools. Sky-power to the people!
