Propellant choice of the serious spudder?

Has anyone ever used cyclopropane, as it wrould have more energy avalible, because of the break down to normal linear porpane then the normal energy released via oxidation.

Hell, while we're at it, use ethene. Or Propan-di-ene would be even better.... Oh, wait, that's what you get in MAPP gas.

There are certain limits to safe fuels- when you start involving double/Triple bonds and ring structures things get risky. Try and avoid them... When you reach Ethyne (Triple bond), you get serious risks.

Most of you will know Ethyne as Acetylene.

Ummm...If he used the force, he would have no use for a giant cannon.

Hehe, sorry, that was the Star Wars jumping out.

I agree, be careful with the "3's" what steel are you using again? What happened to that 200 psi steel that you mentioned before?

Uh... SpudStuff said that.

And isn't cyclopropane used as a tranquilizer/anesthetic? Leaks would be very bad in that case.

Eh, sorry, you're both Spud[insert word here]. I made a mistake, now it's just a generic quote.

That would suck when you had a leak you would faint. Idea: Use it on squrrles. Put a tank partially open on the power poles.:p

[br]I suppose butane would be good but tried and true dependable meter systems seem to be nonexistant unless I am forgetting something.

Sorry, I forgot to add "practical" to my list there.

It's an accurate and dependable system there, but wouldn't be practical at all when you could use onboard propane metering with the turn of 2 ball valves or the push of a button.

<hr height="1" noshade id="quote"></blockquote id="quote">It is as practical as any other fueling system. Perhaps not as fast as a traditional meter but I can live with "slow (30 seconds to fuel) for $5" versus "fast (couple seconds to fuel) for $50".

Anyone ever tried using gasoline and some fuel injectors?
