Thermoelectric Nanorobot Swarm — Pipeline Energy Harvester

A swarm of autonomous thermoelectric nanorobots crawls the outer surface of a hot pipeline, each one sensing the local temperature gradient and steering itself toward the steepest drop the way a distributed search algorithm would — part gradient ascent, part stochastic exploration. Wherever a bot straddles a real temperature difference it generates a Seebeck voltage and feeds real instantaneous power into a shared battery model, so the whole swarm behaves as a self-organizing energy-harvesting sensor network. Tune the swarm size, exploration noise, load resistance and hotspot intensity and watch the harvested power, average sensed ΔT and battery charge respond live.
