I was on the radio during lunch today and I didn't even hear it. I would have forgotten completely, except I happened to catch the end of the hour where they mentioned that within the previous hour I had been talking about steam cooled CPU fans with Eric. We recorded this piece some weeks ago and quite frankly I could no longer remember where I first read about it. No matter, I did a Google Desktop search and it remembered for me. I sure do love having Google Desktop function as my outboard brain. Just call me Philly Mnemonic.
