This is a cool article, thanks for posting. But what puzzles me is how you can see this working on the moon, but don't seem to see how it is needed on Earth far more urgently than needed on the moon, otherwise you would be writing stories on how it could be done on Earth, fixing the existentially threatening energy crisis on Earth, thus helping assure we do go on to explore more of space.
I presume the energy source you would suggest using to supply the electrical current for electrolysis would be solar.
Yet why on Earth do we have so many other contenders, all of which have the ultimate thermodynamic effect of doing more damage than good? (only use of solar has the desired thermodynamic effect of cooling, rather than heating).
