Extended Data Fig. 4: Lab-scale experimental setup.
From: Enhanced solar evaporation using a photo-thermal umbrella for wastewater management
The solar umbrella comprises a selective solar absorber and black emitter which is placed on an acrylic tank containing water. The temperature profile and evaporation rate are monitored using thermocouples and a mass balance, respectively. Holes are drilled into the umbrella to serve as vapor escape pathways.
