New solar still makes tainted water drinkable using bubblewrap

Researchers from MIT have created a solar still made of bubble wrap and other simple materials that can make tainted water fit to drink. Solar stills typically require expensive lenses or other equipment, but this setup allows people to boil and distill water with no extra solar concentrator. The Read More...

This work of art can annually desalinate 1.5 billion gallons of drinking water

Global warming is making drinking water scarcer. Desalination can provide a solution in many coastal areas where most of the world population lives. But desalination requires a lot of energy; making fresh drinking water expensive. “The Pipe” is designed to solve that problem. Here it is Read More...

How do we get more people to purify water using the sun's rays?

Local mistrust is slowing take-up of simple innovations that use sunlight to disinfect water, a UK conference has heard. Researchers working on low-cost, low-tech water purification systems for developing countries are struggling to convince local people that their solutions work, the EuroScience Read More...

Using solar power to turn salt

Using solar power to turn saltwater into drinkable water

Fresh drinking water is increasingly precious. That’s why worldwide hundreds of desalination plants are planned or under way. However, most of them are powered by fossil fuels. At the giant Mohammed bin Rashid Al Maktoum Solar Park under construction near Dubai, a desalination facility goes Read More...
