Today’s state-of-the-art thermoelectric materials are only five percent efficient. Skutterudites, and this new knowledge about how best to arrange their atoms, could help improve their performance to ...

MIT researchers have a new energy storage design that will store heat generated by excess electricity from solar or wind power in large tanks of white-hot molten silicon. It converts the light from ...

Researchers have found a new way to improve a key element of thermophotovoltaic systems, which convert heat into electricity via light. Engineers designed a thermal emitter that can deliver high ...
