That's the coolest thing I've ever seen! (okay, not really....but it is neat)

Nothing wrong with type K or L, just unnecessary to spend the extra money for this type of application.

Wow, I really didn't mean to make you spend more time doing all those calculations for such a small change in results. I'm glad I'm only cooling 5 gal. at a time...good luck to ya 67coupe390!

Good call...I was measuring the wrong thing. Volumetric heat capacity is the amount of heat energy needed to raise the temperature of a given substance by a certain temperature interval. (I love Wikipedia)

Well I've found a definite answer to #4. That is, of course, in addition to what Yuri_Rage had posted (which is perfectly accurate, I just wanted to find out exactly what the differences were) The volumetric heat capacity of water is a staggering 4.184 J, while Copper is 3.45 J. So it seems...

You've got to include the water in there too. He's using +/- 5 gal of water in his recirculation bucket. Plus, now correct me if I'm wrong, doesn't that also mean he's keeping the ice in that transitional stage where it is most effective? "It will then absorb another 80 kcal transitioning to...

I know a lot of you will say that I'm taking this whole thing too far, but we all bring to brewing the skills, knowledge, and curiosity that we apply to the rest of our lives. Plus I really like to ponder questions like this... All things being equal (water temp, air temp, amount of liquid...

Is there any concern about rinse agents, like Jet-Dry? I'm guessing that because it's safe to eat off of dishes that have been in contact with a rinse agent that it's probably safe for our beer, but prolonged exposure (ie. conditioning time) might change the effects...Anyone have any thoughts?

Do take into consideration the type of tubing that is being sold at the hardware stores. There is a substantial price difference between refrigeration, type L, and type K tubing. For all intensive purposes (and correct me if I'm wrong) brewers won't need anything but refrigeration rated tubing.
