Solar-induced desalination and atmospheric water harvesting
Cryogels, polymeric gels formed after freezing water, can be used for solar-induced desalination and atmospheric water harvesting. The EU-funded SWaG project is working on an easy-to-use portable device incorporating the photothermal cryogel. Specifically, it will develop the photothermal cryogels so they generate potable water in two ways. The first is with the solar desalination achieved through solar-induced evaporation of seawater followed by condensation of the vapour generated. The second is through atmospheric water harvesting through the absorption of water vapour followed by water recovery via solar-induced evaporation. The project will serve as a solution for decentralised water production in remote communities and disaster relief applications.
