Are you familiar with the term "carbon foam" ?


I was looking into the idea of a heat sink a few years ago and ran  
across the term.   A carbon mat, basically a woven mat of cotton or  
whatever, is heated in a completely airless environment to very high  
temperatures.

The result is a "carbon foam".      Carbon is pretty much the only  
material still left in the mat, and it now shows some interesting  
properties.

For one, it's extremely heat conductive.    And since heat conduction  
is a similar process to electrical conductivity...  the electrical  
resistance should also decrease.
