An advantage of this process is its mechanical simplicity and applicability to any point on Mars's surface. Its output is not sufficient for industrial purposes such as fuel manufacture,<ref>{{Cite book|title=The Case For Mars|last=Zubrin|first=Robert|publisher=Touchstone|year=1996|isbn=978-0684835501|location=U.S.|pages=|url-access=registration|url=https://archive.org/details/caseformarsplant00zubr}}</ref>{{Disputed inline|talk: Dispute for propellant usage|date=January 2017}} but it may be a useful supplement to life support in some architectures.
