Complicated solution to simple problem

This is the fellow who provided two dozen bike-driven generators to the Coachella festival, and now he's offering his plans up for you to build a pedal-powered cell-phone charger.

Unfortunately, it's a stationary setup involving the use of an automobile alternator and rollers--two things we don't have at hand, and have no intention of getting into hand.

But it provokes an idea: It ought to be hella easy to convert your standard Shimano in-hub magento from a light driver to a cell charger.

Of course, it would be even easier to just not own a cell phone.
