but I don't know about ships - are they run on diesel?

A lot of ships have diesel engines. Biodiesel is popular for marine use because it doesn't blow up so easily and isn't a biohazard. Hawaii uses vegetable oil and fish waste for its biodiesel.

Fish waste? Couldn't they use poi? It's got to be of *some use* to someone, lol.

I guess whale blubber is *out,* too. And we could probably all fly hot air balloons instead of airplanes to go long distances. Oh, geeze, what was I thinking? What about Conestoga wagons?
