C'mon that was not that technical.....BTW...is the text you mention available on line? Googled around a little & couldn't find it...for, ahem ...free. OK so I'm a cheap bastard who's interesed. Actually I am currently looking into the feasability of active rather than passive systems. If the pressure is low enough and the pump strong enough to create a partial vacuum, could a fluid loop take advantage of the latent heat of vaporization? Im sure there would be lots o' cavitation involved, and that the pump would have to wear well under those conditions, but could it be done? With most pumps water would not be feasable ...how bout Freon...123 or 111 perhaps? Not much of a vacuum required with those to get 'em to change phase, and a portion the of pump power will actually serve to cool the load. I dunno... not that deep into it yet to know if it is doable.
