Bennett thought that it sounded like a good idea.

I do too.

But if you are looking on the web for more information on what is being described you will get better results looking for--"cool tubes" "earth tubes" "AGS" which is "Annualized Geo Solar" or "PAHS" which is "Passive Annual Heat Storage." The latter two are mostly about heavily insulated--underground is good--buildings.

Your tubes do need to be way on down there. Eight or ten feet (two and a half or three meters) so as to get to your "average annual temperature" without much in the way of fluctuation. And no ground water--at least for the winter.

I would think that almost any high ventilation will work in the summer, not sure about what one would do in the winter for a small system in a not particularly insulated setting. I know people who blow excess winter heat (solar) from their attached greenhouse into the house with a fairly small fan, mostly just open the greenhouse up in the summer. They've got barrels of non-freezing liquid to absorb the heat for night. Solar only during the winter. This doesn't work on their detached greenhouse.

Here's one link to try--they do talk about how to lower the tubes into the ditch safely:
