Dr. Vaclav Smil's very effective use of 25 minutes on stage at Canada 2020 where he discusses the current realities of global energy consumption.
I attended Worldcon, the World Science Fiction Convention, in Spokane last summer. The event was kicked off by a spectacular talk by astronomer Brother Guy Consolmagno, winner of the Carl Sagan Medal for excellence in public communication of planetary science. I'm looking forward to the science & science fiction panels at Worldcon in Kansas City (MidAmeriCon II) this August. In the meantime, I rummaged the web and found a recording of Brother Guy's talk "Discarded Worlds: Astronomical ideas that were almost correct." The recording is not from Spokane, but from his visit to IHMC in Florida. Enjoy.
