Sunrise to sunset, new window coating blocks heat -- not view      (via sciencedaily.com)     Original source 

Windows welcome light into interior spaces, but they also bring in unwanted heat. A new window coating blocks heat-generating ultraviolet and infrared light and lets through visible light, regardless of the sun's angle. The coating can be incorporated onto existing windows or automobiles and can reduce air-conditioning cooling costs by more than one-third in hot climates.

Heat, cold extremes hold untapped potential for solar and wind energy      (via sciencedaily.com)     Original source 

Conditions that usually accompany the kind of intense hot and cold weather that strains power grids may also provide greater opportunities to capture solar and wind energy. A study found that widespread, extreme temperature events are often accompanied by greater solar radiation and higher wind speeds that could be captured by solar panels and wind turbines. The research, which looked at extensive heat and cold waves across the six interconnected energy grid regions of the U.S. from 1980-2021, also found that every region experienced power outages during these events in the past decade. The findings suggest that using more renewable energy at these times could help offset increased power demand as more people and businesses turn on heaters or air conditioners.

Using light to produce medication and plastics more efficiently      (via sciencedaily.com)     Original source 

Anyone who wants to produce medication, plastics or fertilizer using conventional methods needs heat for chemical reactions -- but not so with photochemistry, where light provides the energy. The process to achieve the desired product also often takes fewer intermediate steps. Researchers are now going one step further and are demonstrating how the energy efficiency of photochemical reactions can be increased tenfold. More sustainable and cost-effective applications are now tantalizingly close.

Preventing magnet meltdowns before they can start      (via sciencedaily.com)     Original source 

High-temperature superconductor magnets have the potential to lower the costs of operating particle accelerators and enable powerful new technologies like fusion reactors. But quenches -- the sudden, destructive events wherein a part of the material loses superconductivity -- are a major barrier to their deployment. Scientists have developed an approach to prevent quenches altogether, rather than simply trying to manage them after they occur.
