Princeton Innovation 2022: Solar powered water filter, Rodney Priestley & Xiaohui Xu

Most solar-powered approaches to water filtration use sunlight to evaporate water, which is a time consuming process. Other water filtration methods require electricity or another source of power to pump water through a membrane. Passive filtration via gravity, as with typical household countertop filters, requires regular replacement of filters.
Princeton University researchers Rodney Priestley and Xiaohui Xu have developed a water purification device that uses sunlight, but does not require waiting for the water to evaporate, condense and evaporate again.

Can't wait to hear more. The world needs this. Would love to hear how you would scale this system and take it to places where it is needed most.
