I stumbled across this video. I'm total speechless. This is Incredible

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.
Finch first discovered geothermal heating in 1979 when he and his wife
built it into their 4400-square-foot dream home to cut energy costs.
Eighteen years later they decided to add a 16'x80' greenhouse in the
backyard. The greenhouse resembles a pit greenhouse (walipini) in that
the floor is dug down 4 feet below the surface and the roof is slanted
to catch the southern sun.
To avoid using heaters for the cold Nebraska winter nights, Finch relies
on the warm underground air fed into the greenhouse via plastic tubing
under the yard and one fan.
Finch sells a "Citrus in the Snow" report detailing his work with his
"geo-air" greenhouses and says anyone can build a market-producing
greenhouse for about $25,000 or "less than the cost of a heat system on a
traditional greenhouse".
