Is using less water the secret to cutting our greenhouse gas emissions?
When most of us think of slowing global warming, we think of reducing car exhaust and power plant emissions – limiting activities that involve combusting fossil fuels. But we rarely draw the connection between the production of energy and another important resource: water. Yet in California, Read More...
Harvesting water from air with solar: a sustainable drinking water solution?
The ability to harvest water from air is a technology that has existed for a long time, even going as far back as the Incas. But success in scaling up this technology has been elusive. The largest hurdle is that the technology is energy-intensive, making it cost-prohibitive with dubious results. Read More...
This wind-powered device could help bring water security to villages
Researchers have developed a wind-powered condenser that is able to provide 11 gallons of drinking water every day out of nothing but air. The device works as a high-tech artificial well, pulling air into a chamber buried below the ground where it condenses into water. Best of all is it runs Read More...

One way of making use of them is by incorporating spent coffee grounds in a foam filter that can remove harmful lead and mercury from water. Researchers recently fixed used coffee ground into a special foam, and they Read More...
Israel makes strides in solar power water distillation system for remote villages
Remote villages around the world that lack access to both electricity and potable water may soon be able to quench their thirst, with the development of an Israeli solar powered water distillation system. The Jerusalem-based SunDwater, whose standalone system harnesses heat through concentrated Read More...
This device can literally pull clean drinking water out of thin air
When kids learn about the planet’s water cycle, they’re taught a simple concept: our atmosphere is filled with water vapor that has evaporated from the bodies of liquid water we see around us. When the vapor’s temperature gets low enough, it gets turned back into water. The Read More...
