Biologic Freecharge
Saw this on Gizmodo today. It's a usb device for your bike that uses a dyno to charge your phone. Pretty useful for long rides or tours where you will never have a dead phone battery. Of course, I'm sure some folks could make there own for less than $100, still, pretty cool.

Unfortunately the dude who wrote the article is a moron who obviously does not ride a bike at all. Sad :(
