Thermophotovoltaic Energy Conversion: From Heat to Electricity via Photons

We unpack thermophotovoltaic energy conversion—how MIT and NREL bypass turbines to convert infrared heat directly to electricity. Learn why gallium antimonide and silicon carbide heat storage pushed efficiency from 41% in 2022 to 44% in 2024, the idea of reflecting unabsorbed photons back to keep the heat source hot, and the potential for heat-based grid storage and self-powering devices. We also discuss practical implications, including cheaper power than lithium-ion batteries and aerospace applications.Note:  This podcast was AI-generated, and sometimes AI can make mistakes.  Please double-check any critical information.Sponsored by Embersilk LLC
