Taking part in a high-visibility event near the nation’s capital means you need to be on your toes. Just ask sustainability scientist Zak Holman, an assistant professor in the School of Electrical, Computer and Energy Engineering in ASU’s Ira A. Fulton Schools of Engineering. He was displaying a technology at the recent ARPA-E Energy Innovation Summit near Washington, D.C., when Al Gore, the former vice president, walked up and asked him about the PVMirror Holman had invented. Holman’s PVMirrors were part of an ASU LightWorks display put on by Arizona State University for the ARPA-E (Advanced Research Projects Agency - Energy) summit. ASU professors, staff and students took part in the three-day event. They had the chance to show off their work to several people, including dignitaries like Jim Yong Kim – president of the World Bank – who was also impressed by Holman's technology.
