Researchers generate heat exceeding 1,800 degrees using incredible solar thermal trapping method: 'This is crucial'.
It takes a lot of heat, mostly from fossil fuels, to make steel, glass, ceramics, cement; ~ 25% of global energy consumption. Scientists in Zurich are using synthetic quartz to trap heat from the sun at temperatures > 1,000 C. Previously, solar heat could only be trapped up to about 170 C. The much higher heat can be used to smelt steel and cook cement.
