I want to know the answer to the following question:
How many coconuts are required to produce 1 liter of coconut oil?
All the background I'm provided with is that "On September 15, 2007, Witon Barry (of the Tobolar Copra processing plant in the Marshall Islands capital of Majuro) said power authorities, private companies, and entrepreneurs had been experimenting with coconut oil as alternative to diesel fuel for vehicles, power generators, and ships.". Is that enough to answer the question?
