Turning the page for contaminated water: These book pages work as a filter
It's remarkable how simple the idea is: This paper sheet filters contaminated water to make it drinkable. The paper contains nanoparticles of silver or copper which kill bacteria in the water as it passes through, and is proving to be full of potential for communities in developing countries Read More...
California is beating the severe drought with innovation
California—where more than half of the fruits and vegetables in the US come from—is in the fourth growing season of a severe drought. And yet, last year, both farm employment and farm revenue increased slightly. As it turns out, Californian farmers are beating the drought. More efficient drip Read More...
Brewery hopes to tap creative minds to deal with drought
It's a new approach to an old-school solution for a state gripped by severe drought: Place a brick in a toilet tank to conserve water with every flush. The new version, dubbed Drop-A-Brick 2.0, will be unveiled Thursday as part of an unusual effort to stimulate water-saving inventions through Read More...
Millions of black plastic balls will help California conserve water
California may be experiencing the worst drought in 1,200 years. Covering the surface of a 12-billion-liter reservoirs with black plastic balls will block sunlight, preventing more than 1 billion liters of water from evaporation.They will also avoid the production of dangerous chemicals than can Read More...

Solar Desalination: The solution to California’s water crisis
California’s drought-stricken Central Valley farming region still has lots of ground water. However, that water is salty because of the nearby Pacific Ocean. Desalination of that water is the easiest way to provide more fresh water to California’s farms, but conventional desalination is an Read More...
Harvesting rain could result in significant saving for many poor people
Of course, it's possible to find technological fixes to ensure there's enough water in barren places in countries such as India. But what about using what's already there? That's the idea behind collecting precipitation in rain barrels. This form of "rain harvesting" could result in significant Read More...
Solar-powered desalination technology to provide drinking water in India
In India, more than half of groundwater is not ideal for drinking. It would be if it weren’t so salty. However, desalination is expensive, especially in villages on a small scale, and requires electricity, of which there isn’t enough. At MIT, researchers have worked on a Read More...
Toilet-to-tap-water policy inching closer to a realistic plan in parched California
California’s aquifers and reservoirs are being drained as the state suffers through its fourth year of drought. Regulators recently started working on the permitting framework for seawater desalination projects. Simultaneously, California water managers and environmentalists are urging adoption Read More...
