02/07/2020 Ultrahigh-efficiency desalination via a thermally-localized multistage solar still
Congratulations to Zhenyuan Xu, Lenan Zhang, Lin Zhao, Bikram Bhatia, Kyle Wilke, Youngsup Song and their collaborators in China for their recent work on ultrahigh-efficiency solar-powered water desalination which was featured on MIT News. This work demonstrated a record-high solar-to-vapor conversion efficiency of 385% with a production rate of 5.78 L m-2h-2 using a low-cost and free-of-salt accumulation multistage architecture. This work elucidates the fundamental limit of the solar-to-vapor conversion process and provides useful design guideline for existing passive solar thermal desalination technologies.
