Hi
So if I want to set up 4 uncorrelated systems, that would require 20
tons of
water split into 4 tubs. Each tub would be roughly 3' x 4' x 15'. Of
course
if they are all in the same basement, I still have a correlation
problem. My
guess is that no matter what I do, any system that controls all the
systems
the same way will run into correlation.
Oils, silicon fluids, and the like mostly hold less heat than water
so the
tubs would get bigger. Maybe a few tons of mercury...
Try about 145 tons of mercury per rubidium source as the specific
heat of mercury is about 1/29 that of water.
This seems exceedingly unhealthy.... 145 tons of mercury in pools in
the basement. Not that I don't deal with mercury at home, but fairly
well contained and giving me readings in mm Hg as I go to work or come
home.
Mineral oil seems more healthy. Not to speak of active systems.
Merry Christmas.
Cheers,

At your location, at present, it wouldnt be a significant problem as
long as the basement was unheated.
Also good ventilation would help, together with a thin layer of oil on
top of the mercury.
The biggest obstacle would be the cost of the Mercury.
