Ore milling | Gold Refining & Metal Extraction Forum

Just a quick breakdown on fuels, versus human output. The energy pricing of a gallon of gas versus 3 guys = say $3.50 for a gallon, to $ 25.00 an hour per 3 guys = $75.00 for the same amount of work. That is if you could find 3 guys willing to work that hard, for an hour, for $25.00. Almost impossible.
