I have just been told about a thermocouple generator that russian soldiers used to use with their lamps to provide power for radios on long missions ne1 know where I could get one they sound like a usefull piece of kit also what about building one that could go under a fire ? The power output would probably be good enough to charge batteries from which would be useful. Also Solar battery chargers just jumped into my head ne 1 know how fast they charge on an average overcast day ?

Lots of questions I know but I like my electricity it does lots of stuff (Raidos torches Gps laptops etc).
 
One good thing about Thermocoupling is you can make power from a source heat, a cold source and two types of wire.
Bad thing?
You need sources of very high (I mean REALLY high) and low (below zero) temps constant enough that would last to produce the needed juice for a recharge.

I look into this futher and Ill tell you what I find.
 
I know how they work ( We just did them in A-level Physics) and it was my physics teacher who metioned them.
 
there is one site that has a lantern that has a thermocouple unit on a lantern like you describe. I thought I had it bookedmarked, but I guess not. I will try to remember where it is and post it. There is one lantern like you describe,but it is expensive.
 
I have a couple of the elements you mentioned. Their size is about 100*200*10 mm vacum packed in SS. At a temp difference of 300 K they give out 3A at 14V. Their main drawback is a given life of 1000 working hours. Otherwise they function as specified, I have not found much practical use for them because of the low life. In russia they have thermoelectric generators working on propane using these elements. For outdoor non-mil use a handwound generator (Freeplay type)would be more practical.
