So basically seal the NG generator in a room filled with carbon dioxide and wheezeworts? (Since CO2 and Chlorine are pretty much the lowest temp gases a Wheezewort can cool without stifling.)

So now Electrolyzers/Water Sieves are the only way to cool hot substances until you can acquire wheezeworts and the AETNS?

Actually the problem with using the standard equation for thermal resistance is that then materials wind up with much lower conductivity than normal. For instance a block of copper conducting heat to a block of copper would do so at 30 W/k rather than 60. The more I look into it, the more I think the geometric mean will create values that "feel" right to people. Of course, given that square roots are a bit more processor heavy than you'd want for something that is calculated for thousands of blocks a tick, it might be best to create a lookup table of material interface conductances.

This really is the best way to handle it. Since there's no square roots involved it should be mathematically simple for the game to calculate. Technically the formula to determine the heat transfer through a pipe from the liquid to the surround atmosphere is U = 1/[(1/h1)+(dw/k)+(1/h2)] Where h1 and h2 are the heat transfer coefficients of the fluids, k is the conductivity of the pipe, and dw is the pipe's thickness.
