Also the specific gravity of propane increases to almost the same as
kerosene at LOx temp. so the low density isn't an issue at cryo temp.
I've seen a proposal to immerse the propane tank concentrically inside the
LOx tank.

The interesting thing you bring up, is that Propane would be a solid in
LOX.
Actually, no, propane is still liquid at the normal boiling point of LOX.
The good news is that they're mostly immiscible -- the two liquids won't
mix much. The bad news is that they're miscible *enough* that the result
is still explosive.
Thanks, didn't look up the boiling point of propane.
With Hydrogen: Fireworks, it would be the Oxygen that is the solid. SOXsafe?
instead of LOX. Powdered SOX in Liquid Hydrogen, interesting, is it
Almost certainly not. Powder has too much surface area. Powdered fuel
in
liquid oxidizer is almost always an explosive, and I bet it works the
other way 'round too.
We are talking about Hydrogen Fireworks, Nano Powder would have more
surface area. But we are not talking about powder fuel in liquid oxygen.
Oxygen is dangerous, making the Oxygen the Solid should be safer than the
other way around.
Also a bit tricky to make. You can't just dump LOX into LH2 -- that will
boil off *all* the LH2, not just a little bit of it. (LOX is much warmer
than LH2, and it takes very little added heat to boil LH2.)
Why not? Why can't you just pipe high pressure GOX into LH2, the GOX turns
to SOX and the Hydrogen boils off to be collected and reliquified. (GOX is
much warmer than LOX so should produce smaller particles if nano injectors
are use to make the SOX.
