Well, I don't know how much Engineering YOU have, but I'm a Mechanical Engineer, and I just happen to know a little bit about engines. There are many on the horizon that could be pretty happy running on soybeans. All we have to have is a reason to develop them, which, like I said, we don't have right now.
Retrofit my Monte Carlo SS with one of those, and I'm good to go.
Sure, soybeans can produce a fuel. But it would be a whole lot more expensive than gasoline, even at current prices.
As a mechanical engineer, you should have a decent understanding of math.
average oil production per acre is about 49 gallons
The US uses about 373 million gallons of gasoline per day
This Week In Petroleum, Gasoline
The US uses about 169 million gallons of distillate (diesel and fuel oil) per day
This Week In Petroleum, Distillate
Looking at only the distillate, and only trying to produce 25% of the current need is 15.5 billion gallons per year. Or in soybeans production 316 million acres
Where is that going to come from?
