Large glass windows provide better natural lighting conditions, but also let in more heat, therefore bringing higher air-conditioning bills. Now a bioinspired microfluidic circulatory system for windows developed by researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University could save energy and cut cooling costs dramatically—while letting in just as much sunlight. The same circulatory system could also cool rooftop solar panels, allowing them to generate electricity more efficiently. Read more »
