NASA gone cuckoo-cuckoo
<http://www.nature.com/news/2005/050516/full/050516-15.html>
MoonROx (Moon Regolith Oxygen)
Would you like a quick $(USD)250K?
"Entrants must build a device, within certain weight and power limits,
that can extract at least five kilograms of oxygen from a sample of
volcanic ash (a substitute for lunar soil) in the space of eight
hours. The first team to build and demonstrate such a gadget before 1
June 2008 will claim the cash."
Given that the semiconductor industry would pay a fortune to directly
isolate elemental silicon from silicate, Uncle Al senses a synergism
here. The only thing standing in the winner's path is
thermodynamics. As silicon foundries will tell you, molten silicate
does not electrolyze to oxygen and silicon. Even aluminum
electrowinning needs the thermodynamic push of anode oxidation.
Maybe if we had a high temperature electrolyte membrane... and a way
to drop the melt viscosity... and our thumb up Tinkerbelle's bottom...
Uncle Al wishes everybody good luck on obtaining the 156 moles of O2.

Different problems completely. There are no economic or energy limits |
on the NASA proposal because they figure on using sunlight as a power
source.

Why worry? It will keep all the alchemists from posting here a while.

Hydrogen added to rutile + at around 900 Centrigrade should give water.
Electrolysis of the water is left as an exercise for the student. |

But moon regolith is silicate. No-go. If you are tanking along
hydrogen then you would more efficiently tank along oxygen. The NASA
spew is obviously free heat from solar focusing plus free electricity
from solar panels, all local. No trucked in material consummables or
you would truck in oxygen.
Ass-tronaught One, "Hey Bob, we just lost our breathing air
electrodes. How may replacement pairs do we have left?"
Ass-tronaught Two, "None. NASA failure anaysis said their MTBF
exceeds mission duration."
Ass-tronaught One, "Demand a meeting to plan a White Paper being
written!"
Uncle Al proposes a high temperature catalyst that will split molten
silicate into elemental oxygen with high efficiency. Reduction to
practice is left as an exercise for the alert reader. (More studies
are needed.)
