I see where the folks at Epicenter (http://theepicenter.com/cgi/order.c...rators_and_batteries.html&cart_id=%%cart_id%%) now sell a series of TEG (thermoelectric generator) based on cook pots. They also now offer a 40w watt unit I don't see offered anywhere else. Worth a look - cook up your noodles and recharge you GPS at the same time - looks to be a lot less complicated than the Biolite stove now making a buzz on the interwebz. I supported remote repeater sites using TEG sets to charge a battery bank. No moving parts and just add heat! Pricy, but worth a look if you have a need to charge electronics out away from "civilization". I've dealt with this outfit, never an issue and very straight in their dealing. What do you think?
