let me explain it in terms even someone as challenged as you might comprehend; > if you have the means to convert a large flask of human excrement and urine into potable water and edible and nutritious 'biscuits' then it dramatically reduced the stockpile of shit you have to take with you and/or pre-position in martian orbit and/or on the surface for someone who thinks in terms of grabbing a snack 'somewhere' along the way, you have tied yourself into an earth-centric mode of transport instead of make your vessel into something that can go anywhere, like a true ocean-going ship. sadly, such machines do not exist as all the money in space research goes into the exciting process of making big sexy engines faster instead of the far-more-useful, mundane and unsexy job of figuring out how to make shit into something edible and filter piss properly. > tldr every nigger wants to make light-speed engines they can boast about to other niggers. not one nigger wants to figure out how to turn a turd into a biscuit that doesn't taste like a dried turd, something you cannot boast about in bar to impress the other niggers like saying 'light-speed engines' permits among one's peers. > spending on engines = $$$$$$$$$$ > spending on flask of shit = 40c i've met your kind before. you're hoping 'someone else will do it'.
