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
