Of my reborn 80 gal W/H. Then connect the bottom of the 3/4 to a T off the bottom tank drain and the top of it to a T at the top exit tap of the W/H and voila thermosiphon!!
The 3/16 would be the condenser of my 5K window unit sitting in the garage. (maryland coast) I figure a window unit might work better than a dehumidifier since they are designed to dump heat into 100° air?
I have a bunch of questions:
Do I need spacers inside the 3/4?
Is 3/16 too small and will the combo thermosiphon enough heat out of the condenser??
Why can't I just watch sports on Saturday like normal guys??
Later plans are for a similar tube in tube ground water coupled evaporator but this is the first bite and I've never even brazed HVAC lines.
Any thoughts??

To make it work like thermosiphone it has to be vertical and vertical part as high as possible. You can have 2 or 3 parallel sections (depends on capacity) but sections must be bertical. I wouldn't worry about inside tube touching outside. Make sure your inside tube is refrigeration one and not a cheapo junk. I would use 1/4 acr tube line. Just start with 1 section 3/4 outside 1/4 acr inside. Make it as high as possible like 8-10 feet. If you discharge pressure goes to high add one more parallel section.
A small water pump would make your life easier but you want a challenge
