The mound that outperforms your air conditioner
Macrotermes michaelseni, a termite species common across sub-Saharan Africa, builds mounds that can rise four to five metres above the ground and extend several metres below it. Inside, the colony maintains a temperature of roughly 30.5°C year-round. Outside, temperatures swing between 3°C at night and 42°C at midday. No thermostat. No electricity. No moving parts. The mound does it purely through architecture.
