MIT developed army suit

the end of the article states
. Both Klett and Conway have started doing research for the government to adapt the foam for use in "personal cooling devices" for military personnel.
I wonder if they will try to intigrate this into the Nanotech suit that is being developed by MIT? or is this before that
Great heat pipe material

You could make a nicely-shaped heat pipe with this stuff, tranferring heat from say, a processor to the outside of the case easily. I'm sure hardware and environmental engineers will have a ball with this stuff if it can be produced relatively inexpensively.
One problem.....

If you read the literature fully you'll find that the thermal conductivity is directionally orienented. So if you go 90 degrees in the other direction of the fibers it basically has a thermalconductivity of 1/5 aluminum. (see table 1 of the second ducument).
This may not matter for applictions like a processor, but cooling other objects with more of a 3-d surface may be a problem.

Great for Cooling UltraDense Clusters & Handhe

This is a great material for cooling supercomputers and ultra-dense servers that would otherwise require more elaborate elaborate liquid cooling systems.
The handheld and laptop market is another area that could really use this to keep the cpu and graphics processor cool.
This sounds like it takes highly thermally conductive polymers like CoolPoly to another level. .

add-on heat conductors for improving air-ventilation on disc brakes... make make WRX even happier:)
useful in supersonic aircraft... conduct the heat away from leading edges much faster than normal.
c'mon, join in... what other real-world apps could this be useful for. if the price can come down, and the production can come up... I can think of a lot more places this stuff would make sense.
I worked for the manufacturer - Poco Graphite

I worked for POCO Graphite in Decatur, Texas up until 6 months ago. POCO is the only licensed manufacturer of graphite foam (POCOFoam is their name for it).
This stuff isn't just good for a heat sink shim - IT CAN EASILY REPLACE YOUR ENTIRE HEATSINK AND FAN! But- heatsinks are only the beginning. POCO has made prototype car radiators out of this stuff that are 6 inches by 8 inches by 1 inch - AND THEY WORK EXTREMELY WELL!
To get an idea of just how well POCOFoam transfers heat, check out this video clip http://www.pocofoam.com/images/foam.mov. You will be highly impressed - I guarantee!
While not the same thing, carbon has been used as a heatsink interface material for years. My DEC Alpha came with a Grafoil pad to use between the processor and the heatsink, in lieu of heat sink paste. It's apparently spongy graphite made into a flexible pad.
