aldehyde-stabilized cryopreservation
it was just next to some single-cell protein things so i assumed they want to just pour a bunch of (glutar-)aldehyde on their food for preservation. wow i hope they have a spare liver, because it would be rough, but no, it's a cryopreservation method, like for tissue samples and so on
they wanted to diy a cryonics in their mobile trailer park with intermittent power from solar panels
