This New Solar Power Technology Generates A Massive
When exposed to concentrated solar radiation equivalent to 135 suns, the absorber plate reached 1,050°C, while the quartz rod''s front face remained at a relatively cool 450°C. What makes this new research
6 FAQs about [Quartz Solar Power Generation]
Can synthetic quartz trap solar energy?
The proof-of-concept study uses synthetic quartz to trap solar energy at temperatures over 1,000°C (1,832°F), demonstrating the method’s potential role in providing clean energy for carbon-intensive industries. A paper on the research was published on May 15 in the journal Device.
How does quartz work?
Quartz is a semi-transparent material that allows light energy to pass through it but blocks thermal energy. This means that as the silicon carbide heats up from the concentrated sunlight, the quartz prevents thermal energy leaking back out, trapping the heat and reducing energy loss in the system.
Can a quartz shield save energy?
Their initial experiments found that the absorber easily reached 1050°C. According to heat transfer models, the quartz shield could enable receivers to get to temperatures of up to 1200°C while keeping 70 per cent of the energy input in the system. Without the quartz shield, the energy efficiency drops to just 40 per cent for the same temperature.
Can solar energy be used to produce cement?
Instead of burning coal or oil to produce cement or steel, in the future solar energy could be used for this purpose. Researchers at ETH Zurich have developed a thermal trap that can absorb concentrated sunlight and deliver heat at over thousand degrees Celsius. The main component of the thermal trap is a cylinder made of quartz.
Could solar energy be a green alternative to fossil fuels?
Engineers have developed a device that can generate temperatures of over 1000°C (1832°F) by efficiently capturing energy from the sun. It could one day be used as a green alternative to burning fossil fuels in the production of materials such as steel, glass and cement.
Could solar energy replace fossil fuels?
Credit: ETH Zurich / Emiliano Casati Swiss researchers have developed a solar energy method using synthetic quartz to achieve temperatures above 1,000°C for industrial processes, potentially replacing fossil fuels in the production of materials like steel and cement.
