It sounds like a wonderfully adventurous design.
I have not been keeping up with the literature, but phase change
media ought to be the way to go.
After all, if four tons of ice could hold a house down with a temp
differential of 20 degreesC or so, then 1.5 tons of wax might have a
good chance of holding the temperature up with a temp differential
of 80-20degC = 60 degrees.
Wonder what the latent heat is? Less than 340 kJ/kg I imagine.
How much did it cost?
