This issue's Special Section, "What's New at the Fuel Dock" (see page 68) dips into the shift to greener fuels-ethanol, already a 10-percent additive in our gasoline, and biodiesel, coming soon to a diesel pump near you. There's a lot to learn about these non-petroleum-based fuels, but what do sailors really need to know?
Let's start with ethanol, which, if you haven't noticed yet, is advertised on every gas pump you're likely to use. And it's here to stay for a while, even though it may not always come from corn and grain. President Bush has made development of a different and potentially more plentiful celluloid ethanol a central part of his energy strategy to reduce dependence on overseas oil.
