John Cramer's latest breakthru is adding an alcohol to 50% peroxide to
make a cheap, easy to handle, easy to buy mono-propellant for his rockets.

Does anyone know more about this combination or other cheap fuel
combinations? Notice I don't consider LOX to be cheap. In large bulk
quanties it may be, but for small amounts the handling equipment costs
alot. (Frozen valves anybody?)

I remember there was an oxidizer made by dissolving a solid oxidizer in
water, what happened to that?

Also there was a hybrid rocket that had a catalyst (in? part of? was the?)
fuel so all you did was open/close the valve for peroxide and it
auto-started. You got the simple design of a mono-propellant engine but
the performance of a hybrid, not to mention a very high DensityISP. Has
there been any more developent on that?

"Another fatality now occurred when a trial was undertaken by a Dr. Wahmke
in attempting to pre-mix hydrogen peroxide and alcohol upstream of the
chamber. The intention had been use as a 'monergol' propellant, combining
oxidant and fuel, but it resulted in a feed tank detonation. "


I guess John knows how to do it better than Dr Wahmke.
