Six technologies that produce clean, safe drinking water
By Cat DiStasio One in 10 people worldwide lack regular access to safe drinking water. In an effort to tackle this most basic humanitarian problem, engineers around the globe have developed a wide array of devices, large and small, that generate clean water. Each year, a slew of innovations aim to make the process easier, cheaper and more portable, as well as produce a yield high enough to make a real impact for some of the 663 million people who suffer from water shortages. Solutions range from using condensation methods to pull water from thin air, turning salty seawater into fresh water, or distributing UV light purification chips affordable enough for people to use at home. Only a few of these technologies are working outside the lab, but the ones that do have so far generated billions of gallons of clean water.
