yeah - I've been doing this method for a couple years now - sold my Therminator once I was comfortable with it.
I can generally hit mid40s by using a sump pump and recircing the ground water through ice once I hit about 90df.
great little trick, eh?
I live in North Carolina and this trick works very well during our summers. I can get 5 gallons down to pitching temps within 20 - 30 minutes.
