Wow, that's crazy. This really does go back 40 years. Amazing that he's still here, with the same status of the project ("non-working prototype phase"). You figure, at some point, he'd just give it up and go into a different line of work. It's just like the show "biggest loser". You look at those folks and you'd think that when they hit 225 lbs they'd do something about it, then at 268 lbs they'd do something about it, then at 317 lbs, then at 354 lbs. Kind of like the ongoing status of Moller.
