That’s brilliant. Thanks for sharing.
Septic’s trickier... keeping human refuse out of the water table around you requires some engineering. An actual septic cement tank can be set on fire inside daily... burning and boiling the sludge to be aseptic. You can capture the heat updraft to sanitize various metal vessels.
Can’t believe I’m even thinking about this... but I think it’s time: They tried to fry us in the 08 financial collapse, Lord knows what next-level frying they have in mind.
