MIT AI model discovers non-toxic, earth-abundant thermoelectric material
ProfBuehlerMIT · x · 2026-08-18
MIT's SparksMatter AI model has identified CaMg₂Si₂, a new thermoelectric material made entirely from stable, non-toxic, and earth-abundant elements. Thermoelectrics convert heat to electricity without moving parts, crucial for waste heat recovery. Current top performers rely on scarce or toxic elements like tellurium or lead, making this earth-abundant alternative a significant breakthrough for sustainable energy harvesting.
