If you want to improve the output of solar energy systems, why not also run them at night? That’s the question researchers in Qatar and Jordan addressed as they successfully devised a system that promises to more than double energy output of current solar power stations.

By combining two concepts—a solar updraft system and a cooling downdraft structure—researchers designed a model that could generate 753 MWh of energy annually. That’s enough to power roughly 753 homes …
