Access to clean drinking water is a considerable barrier preventing developing communities from overcoming poverty, but this solar-powered device uses humidity to harvest water. Developed by Massachusetts Institute of Technology (MIT) Device Research Laboratory scientists, the invention turns vapor into potable water. The MIT team recently published a paper in Science called 'Water harvesting from air with metal-organic frameworks powered by natural sunlight.'
The small device, which uses compounds created by University of California Berkeley researchers two decades ago, is opened at night and then closed when the sun comes up to harvest water. This can produce enough clean water for one person to drink.
Sustainable solutions to provide drinking water are paramount, especially when considering two thirds of the earth's population are affected by water shortages.
