Using CPU Heat to Cool CPUs

I’ve been wading through tons of announcements of new cameras, cellphones and monitors of late, and very few things have grabbed my attention, but the idea of using the heat from a CPU to power a Sterling engine, which in turn powers a fan for the heat sync seems deliciously ironic.

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.

I am reminded of the chimney that used to exist for the Friendly Beige Toaster Macs, from the era before Macs had fans. IIRC, it looked like an inverted funnel and was about 2 feet tall.
