Nebraska retiree uses earths's heat to grow oranges in snow

Completely agree. One of my favorite Kirsten Dirksen videos is about Russ Finch using geothermal energy to grow citrus in a greenhouse located near Alliance, NE. [VIDEO]

Yes I think that would work. Check out this guy, he grows oranges in Nebraska in thermal heated greenhouses. As I recall he talks about cooling as well. He has tubes around 8 feet under the ground running around the yard. [VIDEO]

If this interests you, I recommend checking out this video by Russ Finch, who grows citruses (orange, lemons, etc), figs, pomegranates in his sunken greenhouse in the middle of Nebraska in the snow/20F, and uses geothermal heating (long tubes buried underground) to heat it during the winter months, and cool in the summer months. Really interesting story/concept and I'm hoping to replicate on a small scale when I renovate my back yard in the coming years. [VIDEO]

Almost all the videos on this channel are fascinating btw. Greenhouses enveloping entire houses/villages[0][1] in northern Europe to earthships[2] to someone growing citrus in Nebraska using trenches[3] to entire villages underground in Australia[4] [0] [LINK] [1] [LINK] [2] [LINK] [3] [VIDEO] [4] [LINK] I'd also recommend the channels FLORB and Happen Films though they're admittedly a little corny. [LINK] [LINK] Crime Pays But Botany Doesn't recently did a tour of an interesting alt home as well. [LINK]

This guy grows oranges in Nebraska using very little electricity. He mentions in the video the same principals can be used for cooling. [VIDEO]

Agreed and this has been proven already in greenhouse farming. There are many greenhouse farmers that grow crops that would otherwise be impossible to grow in their zone. One example is a orange tree grower in a very cold zone that can sell oranges to his local community at a tiny fraction of what it costs to ship oranges from California. He still makes a profit and the produce is fresh. Here is a small scale example [1] but I can't fault this guy for keeping it small given his advanced age. I hope I have that much energy when I am older. [1] - [VIDEO]

> My family grew strawberries in eastern Colorado for a few years and one of the big problems was the extreme sun. In order to extend the growing season we used low tunnels to shield to plants from frost. However, the low tunnels during the peak summer months would act like a lens melting irrigation lines and even damaging produce. Sounds like problems more ground-coupling of the thermals would help mitigate. This guy used "Earth Tubes" in combination with partially buried and appropriately oriented greenhouses: [VIDEO]

Even low grade geothermal is pretty awesome. Example: "Nebraska retiree uses earths's heat to grow oranges in snow" - [VIDEO]
