Excellent overview on cooling electronics with water or air cooled 
cold plates.
Also applicable to other areas (eg Stirling engines, rocketry, heat 
exchangers in general).

Worth a look for anyone having trouble with more conventional cooling 
solutions. Touches on microchannels and sintered-bead heat transfer 
methods.

15+  Watt/K with 5 mW pumping power sounds good to me.
