Yeah, just not sure how deep you really need to go. I don’t really want to pay someone to do it but I have a spade I can dig with. Could get equipment if it doesn’t cost much but from what I can tell its generally quite expensive.
I do feel like the speed of the heat exchange might be a bit slower, even if the gradient is higher… though maybe a higher gradient faciliates the speed too

You can, and you can even take it one step further.
I didn’t watch the whole thing, but that’s a pretty cool idea
