Did you know that even before the first diesel engine scientists named E. Duffy and J. Patrick conducted the first conversion of a vegetable oil as a fuel as early at 1853. Over a Century later we are just now starting to utilize this greasy gold and convert it into a biofuel to power vehicles. The fuel is much more prominent in European countries. But with nearly 20,000 restaurants in the 5 boroughs of New York City, we’re creating tons of used cooking oil which makes me think we could be sitting on the next big gold mine.
