feasible but the volumes cooled so far are minimal, and there may be sound
emissions emitted from this device. I attended his talk, and I asked
Garrett of the external noise level. Garrett said it was low because the
chamber was of thick solid metal, and not much sound can penetrate out of
it. Operating frequency was one loud tone, about 300 or 3,000 Hz.. I forget
Notice there are no numbers (size, cost, energy consumption,
etc.), other than "a few degrees below freezing", and we all know that ice
cream likes to be stored at -10 F to -20 F.
Ben& Jerry's was the sponsoring entity.. A way to spend profit
money on research that is not taxed.
