Sun Fold Bike concept is green, sort of creepy

Something about this Sun Fold Bike concept really bugs me. Sure, as design concepts go, it's pretty benign — conceived as a green and relatively portable form of commuter transport, it's a fold-up bike that runs on solar power (you probably could have figured that out from the name). The power is stored in a battery that you can use at night or even to power other gear like an iPod. Nothing wrong there. No, I think it's the vaguely egg-like shape it takes in folded-up form that's creeping me out. That, and the nest-like dish it rests in, which tracks the sun's movements to maximize power absorption when you're not riding it. Yeah, that's probably it. Cool bike, though, and greener than a Segway.
