A study conducted at the Politecnico di Torino, in collaboration with the Massachusetts Institute of Technology (MIT), and published in the journal Energy and Environmental Science, presents a solar desalination device capable of spontaneously removing accumulated salt. In the future, this discovery could lead to the development of sustainable desalination systems with stable efficiencies over time
The Achilles’ heel of water desalination technologies is the crystallization of salt particles within the various components of the device. This clogging phenomenon causes a reduction in performance over time, thus limiting the durability of these devices. Tackling this problem is important to ensure a constant production of freshwater over time. Recently, innovative nanostructured materials with anti-clogging properties have been proposed, with the potential of limiting salt accumulation. However, the high cost of these materials makes large-scale production of commercial prototypes difficult.
Starting from this problem, a team of
