Between provocative panels and one-on-one conversations, yesterday's Future Tense energy conference, "What Will Turn Us On in 2030?," featured short videos in which proponents pitched their favored alternative energy technologies. Watch below, and let us know who you think lays out the best case.
Why Nuclear? Presented by Nathan Myhrvold, co-founder of Intellectual Ventures and chief technology officer of Microsoft, 1991-1999
Why Biofuels? Presented by Wim Vermaas, professor, School of Life Sciences, Arizona State University
Why Solar? Presented by Gary Dirks, director of LightWorks, Arizona State University
