Henry,
Ooooohh....one other really sick thought. A local startup does custom DMLS
powders for EOS 3d printers. They have an aluminum MMC powder that's really
interesting (high softening temperature, high thermoconductivity, high
strength, low CTE, and high fatigue strength--only catch is the stronger
you go, the more brittle it gets). I wonder if they could use their process
with an MMC powder that has the matrix be a metal that is a good peroxide
catalyst, but using the reinforcement ceramic particles to give it an
adequate softening temperature.
Probably not--isn't high test peroxide just below the melting point of
silver? Or am I misremembering (I've always been a LOX guy).

Henry,
Good point. I've seen some 3d lattice structures for heat exchangers, Due
to fabrication methods they were using, they tended to have straight path
designs, but I could easily see a concept that had the path of least
resistance going helically.

If you can actually design the microstructure of your catpack, you want
to think not just tortuous but also helical: you want to centrifuge liquid
droplets out of the gas and onto the surface, as much as you can.
