Current Topic:
How efficient is iron smelting ?
by the way. all you have to do is melt the oxide IN A VACUUM. works great on the moon or an asteroid, not so sure it would work in the martian atmosphere without the use of a vacuum pump/ejector. but at least the pressure vessel wouldn't have to be as thick as it would be here on the earth. no vessel at all would be needed on the moon or an asteroid.
