SAN FRANCISCO -- Soybeans are helping power a debris-removal vessel operated by the U.S. Army Corps of Engineers San Francisco District. Mechanics at the district's baseyard in Sausalito, Calif., overhauled the M/V Raccoon in 2011, to allow its engine to run for the first time on a non-petroleum fuel made entirely from soybeans called B99. The results are already being well received on deck.
