A few months ago (before the recent batch of scandals), Arnold Schwarzenegger gave the keynote speech at the ARPA-E Energy Innovation Summit that several of my colleagues attended. His perspectives as a bodybuilder ("Stephen, how are your glutes?"), a Republican who believes in global warming and the promise of bipartisan environmental legislation, and an action movie star are important and inspiring, and I highly recommend watching the whole thing. If 24 minutes is too long, the first 6 minutes and the last 2 are especially juicy. Enjoy!
