A Quartz Thermal Trap Harnessed the Sun–and Is About to Change Smelting Forever
Eco-friendly advancements promise a cleaner, greener approach to producing essential materials.
A thermal receiver built with a quartz shield achieved temperatures beyond 1000 degrees Celsius, exceeding previous efforts and offering a glimpse into cement and steel industries that can finally ditch coal and natural gas. Fighting against climate change means building, whether that’s large solar arrays, sprawling wind farms, or powerful fission reactors. During the experiment, the research team subjected the thermal trap to the energy flux of 136 Suns, and the absorber reached while the other end of the quartz rod remained a balmy 600 degrees Fahrenheit—successfully demonstrating the material’s heat-trapping effects.
