Okay, I get it. It's not the surface area of the tubes you're talking about it's the area of ground maybe not being large enough to cool the tubes and the air in the tubes.
I think somebody mentioned it would be buried under about a foot of dirt, with between 1 1/2 - 2' of dirt between each 4" tube.
I really doubt at that depth that that area wouldn't be enough to cool a snaking tube. After all, if it had any airflow that wasn't passive, it would be sleight. I could probably just use a computer fan instead of the inline fan.
Honestly, I expected more from this forum. You guys are starting to seem a bit boring.. at least compared to the only other forum I use... for diy working on old jeeps.
Anyone know what's up with the stuffy tude?
