Oil wells produce natural gas as a byproduct, and when there's no pipeline nearby to carry it anywhere, standard practice is to burn it off at the wellhead. Pure waste, permanently, with nobody buying it. A shipping-container generator and a rack of miners can be dropped at that same wellhead instead: • The gas gets burned for electricity instead of burned for nothing. • The miners turn that electricity into blocks, no pipeline required. • The well operator gets a buyer for gas that had zero buyers a year earlier. Nobody's mining bitcoin here to save the planet. The economics just happen to line up. Stranded energy with no other customer, a miner that doesn't care where it's plugged in, and a fuel source that was getting burned off regardless of whether anyone used it.
