I was wondering if it was possible to turn the heat generated by the chip set into electricity. I do know that nano fibers can absorb heat and turn it into energy, but what about a special piece of hardware that sits on top the chip?
Asuming that the special piece of hardware, called the fibres for ease of sake, is mounted up top where the cooler would be. Then the fibres would have to have cooling cababilities aswell, otherwise the chip would overheat.
A peltier (or TEC) could actually generate electricity when heated on one side and cooled on the other. you would have to solder it to the heatsink and then cool the other side to have a big temperature difference between both sides.
Have a look at the third paragraph http://en.m.wikipedia.org/wiki/Thermoelectric_cooling
Peltiers are usually used to cool eg the processor in sub ambient cooling, when applying electric energy one side of the peltier get extremely hot (powerful models can get to 100°C+ and can't be cooled with watercooling) and the other side very cold (-> cold can be used to cool a water loop)
