A Proposal for Symbiotic Molecular Detritivory
Abstract: The current human hygiene paradigm is thermodynamically and ecologically inefficient, relying on vast quantities of potable water as a solvent for waste transport. Drawing on Eric Drexler’s vision of Molecular Manufacturing, I propose a shift toward a "closed-loop" personal hygiene system: Symbiotic Molecular Detritivory (SMD). This system replaces external washing with a symbiotic layer of nanomachinery that recycles biological waste into energy and inert dry matter.
1. The Inefficiency of Macro-Scale Washing
Traditional hygiene is a process of "dilution and displacement." We use ~100 liters of chemically treated water to remove a few grams of sebum, dead keratinocytes, and bacterial metabolites. This is a massive "entropy tax" on our planet. As Eric Drexler suggested in Engines of Creation, once we achieve molecular position control, we can handle matter with much higher precision and lower energy cost.
2. The Detritivorous Power Cycle (Original Concept)
The proposed SMD system consists of a "scavenger" nanofleet. Instead of requiring external charging (which would face the "thermal dissipation" hurdle), these nanobots would operate as molecular detritivores:
Fuel Source: They extract chemical energy by breaking the high-energy carbon bonds in skin oils (sebum) and pathogenic bacterial membranes.
Metabolic Maintenance: The "dirt" itself becomes the energy source for the cleaning process. When the host is "clean," the fleet enters a low-power state (dormancy), activating only upon the detection of new metabolites.
3. The "Bio-Dust" Mechanism: Solid-State Waste Management
One of the most significant hurdles in internal/surface nanomedicine is waste disposal. If nanobots process dirt, where does it go?
My proposal introduces the Inert Dry-Excretion (Bio-Dust) model:
Instead of dumping waste into the lymphatic system or requiring water for transport, the nanobots perform molecular dehydration.
