Re: Thermocouples: alternate power?

[hs <htnbetkf@netcomuk.co.uk>]

I have got a Russian thermocouple, ones used on their space 
 /craft and  there is a respectable amount of power coming out 
 /of it. When I  reverse the proces  (power input instead of 
 /output) i get one surface  very hot and the other freezing 
 /(ice builds up)  You need a lot of  temperature diffrential 
 /to achieve useful outputs.

   The device you're refering to is a Peltier junction device snip

any idea how much these peltier junctions sell for in the US?
Kind regards
