How can I make a thermoelectric ipod charger using a mintyboost, a peltier, and lots of heat?

It appears to use a peltier thermoelectric hooked up in reverse embedded in the layers of the bottom of the pot. And the black control box is either a joule thief or a circuit similar to a mintyboost. As it is so tiny I can not imagine it has a 7805 5v voltage regulator or other similar overly simple circuit. I thought why should I spend nearly $300 on something I can make for $10-$50?
I have also noticed there is a thermoelectric powered lamp on this site. My question is this, does anyone see there being an issue if I modify the thermoelectric lamp project and instead hook it upto a mintyboost to charge a couple of rechargeable batteries. I am not sure what sort of amps lets say a 100w 12v peltier would put out when reversed. I have found one for $8.09 here.
And if I did attempt this (and document it for an instructables), what might I need to do to modify the mintyboost to directly charge from the peltier? I know only very basic electronics, such as what every component on a mintyboost does. So this is basically a project to learn more about electronics. Should I simply follow a solar power mintyboost tutorial?
I have a couple of ideas of how to create the temperature difference for my needs. I was thinking of buying a pack of sterno cans, so I can quickly produce the heat needed and charge my all-important ipod touch in an emergency "holy crap the entire electric grid was fried by a solar flare and I won't be able to charge it ever again" situation. And also experimenting with producing enough heat from direct sunlight using black materials and a "hotbox" (this method will come later as it takes more experimenting).
Side note: This is not my only emergency ipod charging project I am putting together. I am also cannibalizing some garden solar chargers and their joulel thieves, but it's been done to death, and a thermoelectric charger is so much cooler is it not? .. or hotter..
