There are two companies selling thermoelectric converter modules, Hi-Z
and Quantadyne....both URLS are on the index98 page at;
http://keelynet.com/index98.htm
Click on energy....I contacted Quantadyne trying to buy one of their
'cascadable 20 Watt modules' and they were currently in production, so
the guy gave me this explanation that the price depends on how many I
buy, so I said, well one, to do some experiments and he never responded
to that. I even suggested they make an experimenter kit so people could
check them out and come up with applications....I believe they say it wil
operate on as little as 3 degree temp differential...that is quite
amazing for one of these.
