In this Google Tech Talk from about 28 February 2007 you can see Incoming Energy Secretary Steven Chu discussing what he knows about Bussard Fusion about 1 hour 1 minute and 10 seconds into the video. The rest of the talk is about alternative energy, power sources for the future, and how to run a good development program. And what does he know about Bussard Fusion Reactors? Not much. He is looking into it.
I got the heads up from cybrbeast at Talk Polywell.
