Heat-Harvesting Nanomaterials

Abstract:
Engineers have long dreamed of harvesting waste heat from a microchip or car engine and turning it into usable electricity. But thermoelectric materials, which convert heat into electricity, have never been efficient enough to move beyond a few niche applications.

Now researchers at Caltech have demonstrated new materials that could boost the efficiency of thermoelectric devices. They've demonstrated the design using silicon, but say it should improve the performance of other thermoelectric materials, too.
