Sadly the most interesting part, how to get rid of the toxins was not adressed,(reply>), @Andrew Sayler That's probably the case yep! But there's actually an abundance of water on Mars! Just not in a liquid state. So really this whole thing assumes we've figured out an efficient way to extract H20 in liquid form and make use of it on Mars,(reply>), ​@Tommo Carroll Don't both those methods require a large amount of disposable water? Something that you don't have good access to on Mars.,(reply>), Sorry about that, I left it out for time reasons as in a previous video I'd already come to the conclusion that removing perchlorates is fairly easy: either rinse with water and/or use perchlorate-metabolising bacteria
