The reason I agreed to testify when I did was because things were being proposed that didn’t make any scientific and technological sense, and so I thought I should point that out. And then I realized, “Gosh I’m just going to come and say a bunch of negative things about things that won’t work. I better come with suggestions of things that might work”.

To my considerable surprise the suggestions that I came up with [have] had a lot of interest and positive feedback. And basically nobody—and I’ve talked to a lot of people about them now, including people very involved in the actual implementation of these kind of things—nobody has come and said there’s a fatal flaw. So I think that’s quite interesting.
