Re: Optimal propulsion system

Hellosailor;
re: density/BTU; Yes, too true. The only advantage to propane is that it stores indefinitely. My musings were more about the drive-train issues and the other applications you mentioned. Since a freight train uses diesel to run gens to power electric motors; would the same reasons/logic/engineering apply? I suppose not,; as a sailboat does not need to shift hundreds of tons of weight.
