Thread: Cooling provided by heat?

MSI ECOlution motherboard transforms chip heat into fan power!!

Okay, try not to let your mind get blown by the possible time-space paradox we're about to illustrate, but MSI's supposedly introducing a new ECOlution motherboard at CeBIT with an "air powered cooler" that operates on the Stirling Engine Theory to transform the thermal output of its chipset into the kinetic energy necessary to power that same chipset's fan. Of course, as the fan cools the heatsink it deprives itself of energy, supposedly the piston affixed to the crankshaft pulls back down, giving it another potential surge when its heat rebuilds. Supposedly it works at 70% efficiency, so we'll just let the thermodynamics geeks in the audience mull over the possibility and audacity of it all -- they certainly seem to have given up on Steorn at this point.

Awesome cooling method! But thinking about the speed of this kind of fan.

ok maybe a vulgar example but yeah i found nothing else.

its like filtering out water from your urine. the more you do it, the less water you get than the previous time. so after doing it for a certain amount of time, the urine wont be liquidized enough to filter water from it.

this fan wont work for long. the amount of power goes down as time passes. so this method needs a lot of rebuilding and re thinking.
