How To Charge Your iPhone By Turning A Crank

The Reactor iPhone case lets you charge your iPhone 5 by turning a crank to keep your phone juiced up until you find an outlet.

It's only a concept at this point. The guys behind it are seeking crowdfunding to help bring it to market via Crowdsupply.

You can snag one for $129 and a limited number of "early bird" cases are available for $99.
