Amazing year round greenhouse - Geothermal Greenhouse - https://youtu.be/DV2hDmQeZb4

Do you want to know ho to grow your vegetables in the snow? In this video you can see everything is possible. This is update of already proven really great functioning GEOTHERMAL GREENHOUSE.

Yes, geo air thermal greenhouse is the way. I bought an ebook on it and know it should work. I will build one in the future. As for the greenhouse, I like this dome tunnel the best:

Here's another one (I think this was posted in another thread).  Winter temperatures in Alliance, Nebraska can drop to -20°F (the record low is -40°F/C), but retired mailman Russ Finch grows oranges in his backyard greenhouse without paying for heat. Instead, he draws on the earth's stable temperature (around 52 degrees in his region) to grow warm weather produce- citrus, figs, pomegranates - in the snow.

This is the one and there is a better design if you dig further.

Thanks, Audrey. Tell me where to dig for the better design. Thanks.

He has a clumsy website for mobile phone. Better to use your computer to access it.

Been to Chena Hot Springs before.  Located NE of Fairbanks AK.  One of the colder parts of the state in winter.  They generate 100% of their energy needs along with a geothermal heated greenhouse.  We toured the power plant and GH the last time we were there.  It is a resort, but the owner is big into alternative energy and renewable s.  Here is a link to their renewabl energy part of the website.  https://chenahotsprings.com/renewables/

Good. But they have Hot Springs to use, which is not applicable for most of us. I believe that we could achieve NetZero without using hot springs water. Passive solar, solar waterfalls, geo-air, compost heat plus a few solar voltaic panels - Integration of all that are applicable.
