[net.space] Moon chemicals/energy storage

peterb@pbear.UUCP (03/02/85)

	In order to create massive amounts of heat on the moon, I think that
a working fluid can be obtained (aka sodium, water, air, or whatever is
handy) and use a solar mirror to focus suns energy into a confined zone and
pass the working fluid through it. using smaller "furnaces" to drive sterling
engines to pump the stuff around would make it work pretty well. The only
problem I can forsee is finding enough sodium before the first night fell.
This would be a real drag on the idea.

	I wonder if there is free silicon on the moon (pure enough to smelt)
that can be used to produce solar panels. Also are the base chemicals around
that would be useful for making batteries (lead and H2SO4 type of battery or
lithium, or even better: nickel cadium). There are a lot of problem to
overcome before an operation like this could become scientifically or even
economically possible. Lets start thinking about it.

	Could someone post the chemical breakdown of the rocks brought back
from the moon? I think this would help direct the dicussion and the ideas.

Solar panels need semiconductor-grade silicon, which you aren't going to
find in nature anywhere.  On the other hand, it's not enormously hard
to make if you have the right equipment, and there are plenty of
silicate rocks on the moon.

Lead, nickel, cadmium, maybe.  The moon is badly short of hydrogen, and
probably sulfur as well.  Lithium is a rare metal anywhere, for quite
fundamental reasons.

Some other things the moon is short of are nitrogen and chlorine, by
the way.  Both of them rather important to life.

One possibility, though, is that there may be frozen volatiles (water,
etc.) in some of the lunar polar craters which contain areas that are
permanently in shadow.  A lunar polar orbiter with remote-sensing gear
is what we need to settle this.
