What about coal gasification? Could that be done on a smaller scale than industrialization, say for a couple of homes in coal country?
Yes, If coal was readily available, that’s what I would concentrate on. In fact, there was a website a couple of years ago you could by a small unit( maybe 10x10x 12 ft tall) that you could have on your own property. Hitler ran his whole war on coal and did pretty darn good with it. My dad flew B-24’s to Ploesti to blow up the oil refineries, but stopping coal was much tougher. There is no doubt coal could supply all your needs with some land and some automation to feed the plant.
