New solar-powered water filter could solve the problem of providing off-grid clean water
Apr 1 2021
A new invention that uses sunlight to drive water purification could help solve the problem of providing clean water off the grid.
The device resembles a large sponge that soaks up water but leaves contaminants - like lead, oil and pathogens - behind. To collect the purified water from the sponge, one simply places it in sunlight. The researchers described the device in a paper published this week in the journal
Advanced Materials.
The inspiration for the device came from the pufferfish, a species that takes in water to swell its body when threatened, and then releases water when danger passes, said the device s co-inventor Rodney Priestley, the Pomeroy and Betty Perry Smith Professor of Chemical and Biological Engineering, and Princeton s vice dean for innovation.
Although early reporting portrayed sub-Saharan Africa as being largely spared from the coronavirus pandemic, an international team led by Princeton researchers reported that determining the true impact of the novel coronavirus in sub-Saharan Africa may be complicated by a tremendous variability in risk factors and obscured by surveillance challenges. The researchers developed an interactive online tool for estimating severe coronavirus infections per country based on the impact of various risk factors, such as chronic diseases and access to healthcare.
