How do I dig a big hole?

No kidding about copper. Reels that used to cost 3k now are going for 12 k. The 1 1/2" inch sticks at Lowes are like $127, wow.

Hmm, I'm between 72-75F. Maybe someone could crunch some numbers and tell me if it's going to crash and burn? lol

Well, crunching numbers would tell you much but you need to identify your parameters first. Honestly with the soil temps that you are going to see in a trench, you won't get enough cooling. You need to consider a deep bore hole, something on the order of 200 feet. Like I stated above, once you take into account all of the costs involved in an earth cooling design a packaged chiller does not really look that bad.

One more thing, running the underground pipe in copper would be a huge waste. Use something like PEX, your results will not vary that much.

Well, I'll test it when I get it to the full 14ft deep. If it doesn't work out, I'll use it as my dry ice launching tube. The tube fits tennis balls and 20oz bottles perfectly. No risk of explosion.

It sounds like you're digging a big hole for yourself.
