Both got through to here.  Sometimes you need to give us time to think
and catch up on our e-mail, I'm just getting to the middle of last week
today!

  (You should SEE the disaster on another list I'm on, some jerks are
using that list to harass other people they have a political beef with,
so umpteen huge rants are being exchanged.  I'm going to help in the
solution, which is fine with me!  But it's taking some time...)

  On a really cold day, I'd worry about hypothermia, is all I can say
just now (It's been a DAY!)  You're converting heat flow to power, I
don't know how efficiently, on days way below 65 degrees F if you're
pulling lots of heat out of some people they could freeze, others would
be happy to be cool at last <G>
