Termite mounds are meter-sized structures built by millimeter-sized insects. These structures provide climate-controlled microhabitats that buffer the organisms from strong environmental fluctuations and allow them to exchange energy, information, and matter with the outside world. By directly measuring the flow inside a mound, we show that diurnal ambient temperature oscillations drive cyclic flows that flush out CO2 from the nest and ventilate the mound. This swarm-built architecture demonstrates how work can be derived from the fluctuations of an intensive environmental parameter, and might serve as an inspiration and model for the design of passive, sustainable human architecture.
