I noticed LockMart's CEV proposal used nitrous oxide as a
monoprop; I'm curious about the Isp and the possible catalyst.
Seem like the performance would be somewhat low, despite
the advantages of low toxicity, easier handling and simpler
system overall. I don't recall nitrous being used this way
before; is it something new?

(Oops, never answered this one...)

I'm curious about the Isp and the catalyst myself. :-) There have been
some ground experiments with N2O monoprop systems, but nothing that's
flown, as far as I know. Performance wouldn't be great; they're obviously
trading off performance for easy handling.
