If the alcohol comes from oats, do you get your brownie points for a
"renewable" fuel?

I got a 5 gal pail sample of furfuryl alcohol sent from Quaker Oats free.
Unusually high density too, 1.13,for a fuel and alcohol. Stinks to high heaven
though. By-product of oats processing also a waste product so they'll love to
sell you as much as you can combust.

The part they gloss over, alas, is that it's the *oxidizer* that's the big
threat in the classical hypergolics -- the hydrazines are dangerous, yes,
but it's the N2O4 that's really bent on climbing out of its tank and
killing you right now. And this still needs an oxidizer.
The fact that it's a solid is also rather an inconvenience.
If all you want is something that's not hydrazine and is hypergolic with
WFNA, that problem was solved long ago: furfuryl alcohol is a fairly
inexpensive, stable, carbon-neutral, reasonably-safe industrial solvent
that can be bought by the tank-car-load today. Hard to get research
grants for studying it, though. :-)
