Re: [PSUBS-MAILIST] Propane sub

	Yes we can get back to a technical discussion. I might proffer
that while a propane engine might provide an excellent means of generating
both locomotion and/or power, it might be better used to power a
compressor and use air as your deballast gas. That way you aren't using
fuel to deballast your tanks, just readily available air. Subs using
air-breathing or even air-independent engines to power compressors at the
surface have a long and proven track records for increasing range at sea.
If that's your goal, you might consider looking at that option rather than
deballast with propane. People do this with diesel already, right?
	It is totally possible that I have missed the point on this one.
If that's the case, don't take my response as a personal attack.
