Seriously? I have to say: I don't buy it. I really don't believe that you could pull enough power to charge an iPhone out of an inducting yo-yo, but that is apparently exactly what the iYo Yo-Yo claims to be. It's not actually in production yet (or even produced, singular -- there's a demo of a rendered unit running on the site), so I'm as skeptical as James Randi at an astrologists' convention.Not to mention that nothing developer Peter Thuvander would actually be able to release could have that logo on it -- even if it did work, Apple would just release their own anyway, and then pay Pete twenty years later, right? But some people will do anything for alternative energy these days, including believing that a yo-yo could power your iPhone. Someone call the Mythbusters!
