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...
Water fund to slake Cape Town's thirst by restoring native bush
Cape Town is planning to launch a new fund by the end of 2017 that will improve its water supply by restoring the native shrubland plants covering the region's watersheds and aquifers. Amid uncertain rainfall patterns as the planet warms, protecting indigenous vegetation should yield more water for Read More...
How to wash your hands reducing your water usage with 98%

This 'thirsty' concrete absorbs 880 gallons of water a minute
Tarmac has created Topmix Permeable, a porous concrete that allows rain water to flow though it. Up to 880 gallons of water can trickle through Topmix, which could eliminate flooding where it has been installed. Follow TI:On Read More...
US scientists test tiny water purifier powered by light
US scientists say they have invented a tiny water-purifying device, which is about the size of a person's fingertip and harnesses light to kill harmful bacteria. In laboratory experiments, the ultra thin 1cm-by-2cm miniature tablet-like device, which was placed in a water container, killed 99.9 Read More...
Coca-Cola follows up on promise to replenish all the water it used

Solar-powered Ring Garden marries desalination and agriculture for drought-stricken California
With roughly 80 percent of California’s already-scarce water supply going to agriculture, it’s crucial for the state to embrace new technologies that shrink the amount of water required to grow food. Alexandru Predonu has designed an elegant solution that uses solar energy to power a Read More...
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...
