Re: What about Oxygen?

"the production of fuel from simulant Martian atmosphere has already been tested"

I've no problem with the possibility of obtaining fuel ( from CO2) from the atmosphere it's the extraction of oxygen from a very dilute mix of other gases that I suggest will be a very energy intensive process. Probably better to produce hydrogen & oxygen from any available water even though that will also be very energy consuming esp. to produce/store liquid oxygen
