Nope , there isn't and it has been disproven here many times already
==========================
Can you show some rough numbers? State your assumptions about how many
quadrillion BTUs are needed to eliminate foreign oil imports? Best
crops? Yield per acre? Every time I run these numbers in a spreadsheet,
I get 'a lot of land' needed, like about 10 or 15% of the sq miles in
continental US, and others here say 20% of land is arable, so some
significant percentage of foreign oil import COULD be eliminated with a
lot of biodiesel acres.
