Oxygen is dangerous, making the Oxygen the Solid should be safer than
the other way around.
Why do you think there would be a difference? What matters is lots and
lots of surface area exposed to the other reactant.
Also a bit tricky to make. You can't just dump LOX into LH2 --
that will boil off *all* the 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.
You'd need your own hydrogen liquifier -- storing sizable amounts of it
to be liquified later is not very practical.
And even so, you'd want to prechill with something else, to keep the LH2
consumption (and the cost) down to the merely-ridiculous level.
