Using wood to charge cell phones/laptops/netbooks . . . :fuelfire:
http://biolite.myshopify.com/
So, now you can cook a meal, stay warm, and charge your cell phone all with one fuel source--wood! :thatsright:
:fuelfire:

Have fun. Like a campfire, you can sit around the CampStove and watch the flames dance as you roast marshmallows and tell stories with friends.
Packed size: 8.25 x 5"
· Weight: 2 Lbs 1 oz / 935 grams
WTF?

A thermocouple, basically, attached to the side of a twigs-'n'-sticks backpack stove. The tthermocouple, a type of ransducer, is just a large version of the temp sending unit in a gas stove or furnace. The simplest form is two wires of different alloys that are in physical contact where the heat is applied, electrons flow between them in one direction when they are heated, producing current (in most applications, enough to operate the temperature guage). There are particular combinations of alloys that the engineers who design these use, they have to not only maximize the flow but both metal have to be relatively corrosion-proof and easily withstand the heat range for the source that will be applied.
Not so sure about this, they applications demand a pretty high output for a thermocouple, and they would also require a pretty prolonged time with a sustained heat to accomplish the charging, even if the output was up to it.

Back in the day, the Army and Navy used to use radiothermocouple generators: that is, a thermocouple strapped onto a uranium pile. Apparently it was a fairly compact and reliable way to generate electricity (up to 1MW capacity, according to the stuff I read about them as a kid) in places where getting reliable stocks of fuel oil for a generator was a bit problematic (like the Antarctic).

WTF?
I'm thinking about getting one just to see how well it works.

I have been thinking of a way to hook up a TEG to my wood stove. The problem being a way to keep the cool side cool. So far my idea requires cutting holes in the wall to the outside and the wife wont go for it! I do wish I had an outside wood boiler. If I did I would have some hooked up by now.
