The experiment involved titanium nanopowder, not tungsten. But I see now that there have been experiments using titanium in which power was produced; in several, around a single watt, and in one, 76 watts. So if Brian Ahern's anecdotal data are allowed, titanium can yield both power and localized cooling (perhaps energy is being fed into the system from the power outlet to accomplish this). Eric
