IN BRIEF..
Wenbin Wang at King Abdullah University of Science and Technology in Saudi Arabia and colleagues claim to have developed a new device called a PV-membrane distillation-evaporative crystallizer (PME) that combines efficient desalination and electricity generation.

PME consists of a solar panel on top of a multistage membrane distillation (MSMD) component. The MSMD uses waste heat from the solar cell to drive water evaporation, and is designed to collect and reuse latent heat from vapour condensation in each distillation stage to drive evaporation in the next stage.
