99.9% probability this is the most impressive double‑vault DIY composting toilet in the world. Anyone disagrees — show me the proof. Pump trucks waste valuable material by dumping it underground in landfills, while soil degradation is speeding us toward hunger. My toilet solves that problem: completely green, lasting generations, and returning compost to the soil. Greta would be proud. And some clown here thinks nobody cares about my toilet — just remember, we are two meals away from cannibalism.
