Has anybody ever thought about using graphite or am I completely insane? Would the texture of the graphite cause problems with the heat involved? Basically we're still dealing with Carbon.

I know that the structure of graphite is obviously different than that of diamond. Would that different structure cause graphite to "grab" the heat differently?

Maybe I'm just going out on the broken limb? Who knows. Like I said earlier, just one of those random thoughts. Thanks for any input. :shrug:
You are right that graphite and diamond are different in structure. This affects the thermal conductivity completely. I will post actual values, but graphite is only good at conducting in certain directions, which is not much use for us.
