My understanding is that Donald Safeway was investigating (2005) this as a way of producing metals in space where one can’t really vent gases into the local atmosphere, or have copious amounts of carbon for reduction: https://www.nasa.gov/sites/default/files/atoms/files/sadoway_1.pdf https://www.nasa.gov/sites/default/files/atoms/files/sadoway... I could be wrong, but couldn’t this be counted as one of the benefits for NASA and research into space?
