"Materials Refining for Solar Array Production on the Moon"

This report was originally a white paper on a process sequence for a
proposed materials-processing test. The test never got beyond the
conceptual design stage, but I presented the information at couple of
workshops. Then with some renewed interest in oxygen production on the
moon, I revised the process sequence to focus on oxygen production
(with silicon and metals as a byproduct) instead of silicon and metal
production, for publication in a technical journal. However, I thought
there may still be some interest in the concept of lunar refining of
the materials to make solar arrays, so I decided to make the original
version available as a TM, and here it is.

It should be available as a pdf on the NASA Glenn technical report
server soon

but if anybody would like an actual printed copy, send me an email with
your address.
