Re: Just add water

On the advantages of water over ammonia (heck, I started
the ammonia bit, might as well defend it :-), the point
I see is that although water is safer than ammonia, they
are both waaaaaay safer than LH2 at 13 K (or whatever).
I also don't recall which is more abundant, methane,
ammonia, or water.

Now to extoll the virtues of water:  Why should you be
worried about being unable to convert water to H2?  All
you need is some electricity and two wires.  Once you
generate a small amount of H2, you can run it through
your fusion plant to get more electricity, and so on.
"Damn, only two hours of air and we're out of fuel.
Frank, bring that pitcher of water, and we're gonna
have to bust your flashlight."

Do you even need electricity?  I always thought burning
unrefined fuel was like sending H2O straight through the
fusion plant, where the heat would be enough to break the
hydrogen and oxygen apart{.  Drive failures would be caused
by extranneous oxygen "clogging up the valves".  Hmm, more
to think about...
