Simplifying, that is a semi-underground greenhouse (the Native American word for it is "Wallipini") which faces the sun, uses thermal mass, etc., and duct work underground below the frost line, with a push fan and a pull fan. Like the push and pull fans on a tower PC.
Not to make it sound like I am diminishing this man's work. Quite the contrary, I am super impressed with him and what he has achieved here.
Also, if you are digging a well, you can drop a loop down there.
Once you go below the frost line, the earth is around 68F year round.
I saw this little gem the other day and enjoyed how low tech it was. This is in AZ (Tucson, I believe) so this would not work where one has a real Winter. But actually I'll wager that it could work in a place with a real Winter with some changes (deeper hole for the container, insulated pipe, etc.).
Dump water in a hole, let the earth heat it into steam, run that steam through a turbine and you'll have power.
Alternatively, use that heat directly to heat your house. Great and very reliable technology, just expensive to build but cost practically nothing to operate as you need to drill very deep to access the heat.
I love the idea of geo-thermal. I haven't studied it enough to know any drawbacks or ramifications though.
Btw, how about growing citrus in Nebraska? With no HVAC?
Yup.

You can effect a form of geothermal. I wouldn't say it's easy to do, but it's fairly understandable how to do it.
It ain't gonna cover your electric bill, but it can cover all or most of your heating/cooling bill.

Would love to make one of those for a shed as an experiment.
That's cool! The hot springs up here has a geothermal greenhouse. I think it's impressive when people figure out how to "nature better".. lol
