Comment on: The Plight of the Martian Farmer

At least protein itself is a &quot;solved problem&quot;.<p>There&#x27;s a couple companies making protein from air and nutrients:<p><a href="https:&#x2F;&#x2F;www.airprotein.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.airprotein.com&#x2F;</a> <a href="https:&#x2F;&#x2F;spacemilk.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;spacemilk.com&#x2F;</a><p>And Air Protein claims they leveraged NASA&#x27;s research into the problem so that&#x27;s a nice payoff.<p>Algae cultivation would be valuable too:<p>Complete Protein: Packed with all nine essential amino acids (Spirulina and Chlorella are up to 70% protein by weight).Vegan<p>Omega-3s: The original marine source of essential EPA and DHA fatty acids, offering a pure alternative to fish oil.<p>Gut Health &amp; Fiber: Rich in unique prebiotic fibers (like alginate and fucoidan) that feed healthy gut bacteria.<p>Vitamins &amp; Minerals: High in essential nutrients, including iron, calcium, magnesium, and hard-to-find vitamin B12.<p>Powerful Antioxidants: Contains protective plant pigments like astaxanthin and beta-carotene for immune and skin health.<p>Natural Food Additives: Provides functional ingredients like agar and carrageenan used to thicken and stabilize foods naturally.<p>I&#x27;m sure there&#x27;s other &quot;food from a vat&quot; options that could be baselines, and then augmented by real plant food.<p>In the interest of efficiency they&#x27;d be best served by having a predominantly vegan diet but I imaging that they could have more efficient producers added in, like chicken and fish.
