Actually, no, it is not conductivity that primarily determines how rapidly something warms up with heat flow, it is heat capacity and mass. Of course, as I said, conductivity also comes into the formula but that primarily affects the distribution/homogeneity of temperature within the object. > _Vacuum_ is an awfully good insulator, and there's a lot of it outside > the habitat. ;-) This is obvious but irrelevant to the question I was discussing. > The surface temperature of the habitat would be almost entirely > determined by radiative equilibrium, taking into account the Sun's > luminosity and distance, the albedo of the exterior of the habitat, > and the amount of heat in excess of that coming from the Sun generated > by the people and equipment inside the habitat. Yes, obviously. I didn't say anything different. But you aren't addressing the question, which was about the AIR inside the habitat. This will be greatly affected by the temperatures of the inside surfaces of the habitat in contact with the air. And as I said, the endcaps are not likely to be at the same temperature as the air in contact with the surfaces. -- "Erik Reuter" <[EMAIL PROTECTED]> http://www.erikreuter.net/ _______________________________________________ http://www.mccmedia.com/mailman/listinfo/brin-l
