A recent CNN interview has revealed that Segway inventor Dean Kamen often loses sleep about giving up on a project that he knows deep down will never pan out.

"You end up lying there saying, 'I'm not stopping. It would be an act of shallow cowardice. Or you decide to quit and you say, 'This is one of those ideas that just isn't going to work,' "

Obviously, Dean Kamen's hope for a transportation revolution never came to fruition for two main reasons: price and the overwhelming dork factor. I mean this sort of thing is just bad publicity.[CNN via Jalopnik]
