Outdoor operation of the contactless solar evaporation structure. a Photograph of the outdoor experiment on the MIT roof using a stationary (non-tracking) solar concentrator. b Solar irradiance (global horizontal) measured over the course of the test day, October 21, 2017. c Performance of the CSES during the outdoor experiment. Solid lines are measured values and dashed lines are modelled values from the transient model validated vis-à-vis the indoor laboratory experiments
