Say what? The insulating ability of the material used doesn't affect the heat flow rate, which will still match the heat generation rate. Rather, it affects the temperature on the "hot" side. Use a better insulator, and after things get rolling, the core will be hotter, but the rate at which heat flows out will still equal the rate at which it's generated. So, when you say it would "barely" work with copper, you must mean that the core temperature would approach some critical value at which something bad would happen. And when you say it would not work with steel, you must mean that the core temperature would be above some critical temperature, and something catastrophic would happen. What temperature might that be, and what catastrophic thing would happen? Are you claiming the core temperature would have to be hot enough to melt the steel shell, or what? Please explain, because it's not clear from your prior posts.
