The technology to remove salt and other contaminants from water is now contained in a chip the size of a postage stamp. Created by scientists and researchers at MIT and in Korea, the tiny portable desalination units were created to help provide drinkable water in disaster areas, with a process called ion concentration polarization.
Designed to operate via solar energy or batteries, an 8inch (20.3cm) wide array of the chips has the ability to produce four gallons (15.2 liters) of clean water every four hours.
Although still in the testing phase, the unit is able to clean small plastic particles, protein and human blood from Massachusetts’ beachwater and produces 99% pure drinking water.
