I am reposting the following to the list. It came through OK but when
archived it stopped after the first paragraph. The only thing I notice
different is a right facing arrow that I did not put in the original
email, so the program inserted it...if this email goes through and shows
up in its entirety on the archive, then it will have been due to that
right arrow.

Hi Henry et al!
You asked about Constantan, which is used in the Dotto Ring to produce a
giant heavy duty Peltier junction, some of the following URLs are about
Constantan;
http://www.hpmetals.com/Tech_constantan.htm
Constantan is a copper-nickel alloy that contains specific minor amounts
of additional elements to achieve precise values for the temperature
coefficient of resistivity. Careful control of melting and conversion
practices result in a very low level of pinholes at ultrathin
thicknesses. The alloy is used extensively for foil resistors and
strain gages.
Excellent document on theromcouples (produce current when exposed to
heat) is located at;

They are fun to play with. Norman Wootan kindly gave me a couple to
experiment with, one is a fat monster and when you connect it to a DC
current, it gets cold enough to form FROST...about 2-3 amps at 12vdc to
do that...interesting effect...(thanks Norm!)...we even speculated at
that time that perhaps the cooling effect associated with Sweet and some
free energy/gravity control experiments might be this exact kind of
thermal redistribution...Norm's idea mostly...<g>...but it sure has
merit as all will see shortly...<g>....thanks to another friend from
Idaho.
