> My grandpa’s village is a popular spot, every house is renting out their garages at crazy high prices, I’ve seen videos of rigs worth hundreds of thousands sitting in the barn in shelves next to the cows who use the heat.
I'd like to question the "cows who use the heat".
Its the other way around. https://www.vpr.org/vpr-news/2018-01-04/in-deep-freeze-how-o...
> "I read somewhere that each cow generates 2,350 BTUs. We have 255 of them in here keeping this barn warm," Sweet said. "It's hard to believe a barn this size there's no heat in this beside the cows." Sure enough, some sources say cows give off 4,500 BTUs per hour. The barn does have insulation in the ceiling and end walls, and the side curtains have an R-value of 2. They leave the equipment they use daily in the barn so it doesn't freeze up.

> "One cow gives off 4,400 btu's per hour. Our Dairy-Aire system recovers 2,500 btu's. A 60-cow herd will easily heat and cool the average 1,500 to 2,000 sq. ft. home," Lussenden told FARM SHOW, noting that the system can also be installed in high capacity hog, poultry and other confinement buildings.

> It wasn’t long before the inventive engineer realized that, since a single cow gives off 3,500-4,000 BTU an hour, a mere 15 milkers could provide sufficient excess warmth to heat a standard 2,000-square-foot home.

The cows don't need mining rigs.
