Solar Evaporator Offers A Fresh Route To Fresh Water

We had a lot of posts about solar-powered devices which are using for making drinkable water out of salty water. But most of these devices are far too expensive to install and operate in many locations, especially in low-income countries and remote areas.
According to SolarDaily news, researchers at the University of Maryland’s A. James Clark School of Engineering have demonstrated a successful prototype of one critical component for affordable small-scale desalination: an inexpensive solar evaporator, made of wood.
The design employs a technique known as interfacial evaporation, “which shows great potential in response to global water scarcity because of its high solar-to-vapor efficiency, low environmental impact, and portable device design with low cost,” says Liangbing Hu, associate professor of materials science and engineering and affiliate of the Maryland Energy Innovation Institute.. “These features make it suitable for off-grid water generation and purification, especially for low-income countries.”
Interfacial evaporators are made of thin materials that float on saline water. Absorbing solar heat on top, the evaporators continuously pull up the saline water from below and convert it to steam on their top surface, leaving behind the salt.
