Those numbers just don't seem right. 3.6 gallons a day time 100 million pigs would be 360 million gallons a day. There are 42 gallons in a barrel of crude, so that would be just over 8.5 million barrels of crude in a day. Considering we import just over 10 million barrels of crude a day, you're proposing that we could basically eliminate all importing of crude oil using pigs. I doubt that very much.
