> Now we are talking about mirrors, temperature control, salinity control, food sources, killing competing organisms, water intake and filtering lol, this comes across as FUD. Mirrors aren't high technology. They have no moving parts and do not require batteries. Temperature control? Keep it the same temperature as your habitat, you should already have parts for that. Heck, keep it in your habitat. But algae isn't that sensitive, it can operate over a temperature range. Salinity control is absurd, who's putting salt in the water and why can't you just tell them to stop? Water intake and filtering? What? Dude it's essentially just water in a transparent container. There's no flowing or filtering. Killing competing organisms? Algae is the competing organism, it can take care of itself, even if we brought competing organisms to Mars, which would be a silly thing to do. I mean, maybe radiation is a factor, I don't know, but all that other stuff is not challenging. And you're spending so much time inventing "challenges" for a simple algae farm, while just handwaving at a device that needs to compress the gas and heat it to 800 degrees celsius? I'm not saying MOXIE won't work, or won't be useful in some circumstances. It's just that I don't understand why it's supposed to be simpler than tried-and-true alternatives.
