In a remarkable shift away from fossil fuels, researchers have developed a method with thermal mapping to achieve temperatures over 1,800°F (1,000 degrees Celsius) using solar energy — a significant leap toward clean energy solutions for heavy industries like steel and cement production.
Typically reliant on carbon-intensive fossil fuels, these sectors could see a transformation as this solar technology promises a sustainable alternative for high-temperature processes essential to modern civilization.
Pushing solar energy to new heights
The concept, which has been detailed in a recent study from a team in Switzerland, revolves around the use of synthetic quartz to trap solar energy effectively at extremely high temperatures.
This innovative approach utilizes a semitransparent quartz rod paired with an opaque silicon disk, which serves as the energy absorber.
When exposed to an intense light equivalent to that from 136 suns, the…
