A compact flat solar still with high performance

Guilong Peng et al.

Summary: The solar still is a convenient off-grid device for desalination, with the flat solar still (FSS) being proposed as an alternative to improve efficiency and productivity. The FSS collects condensate water using capillary grid and shows enhanced mass transfer, leading to higher performance and energy efficiency. The FSS can also be easily extended to more stages for latent heat recovery, paving a new way in designing and optimizing solar stills.
