This is a small steam driven 5 volt generator for most Nokia and other phones that use the a 5v charging system.
A long metal reservoir to be placed on or near hot campfire coals holds some water. The entire unit is long enough to place in the fire without having to get too close to it, and the
end stays cool enough that you can fish it out of the fire when it's done charging.
The water in the reservoir boils and creates steam, which drives a small turbine and generator creating voltage, which is then regulated to 5 volts to compensate for higher or lower turbine speeds when the fire gets hotter or the water runs low. A pressure release valve helps prevent Darwinism if the fire is too hot. An extra long heat-resistant charging cable keeps your phone away from danger.
Perfect when camping. Stops working when it stops whistling. Much more fun than the windup charger.

It better go "choo-choo" or I want my money back. |

Seriously, upon reading the title, I thought this was a method to remove all the ear gunk from your cell. |

Glad to see you back, Burnsy! |

Won't work well with a turbine; would be more efficient with a reciprocating engine. Something akin to this was used to power radios in remote areas during WW II. |

You're sure stuck on the 5 volts thing. Why not a user selectable voltage? |
