Solar Desalination: The soluti

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...

Fortunately, a Massachusetts-based software engineer has invented a device that makes it possible to polish your vehicle with merely 1.5 Read More...

California lays the groundwork

California lays the groundwork for seawater desalination rules

In its fourth year of drought, with depleted aquifers and compromised farming communities, California is moving forward to securing the Pacific Ocean as a new source of water supplies. Assuming that the future will not look like the past, regulators started working on the regulatory framework for Read More...

Lima is relying on an ancient civilization’s technology to alleviate drought

With its 9 million inhabitants, the city of Lima, Peru, is exposed to water shortages during its seven-month long dry season. Rather than building a desalination plant, the city's water utility company, Sedapal, is to invest in conservation projects to keep the rivers flowing more reliably Read More...

California aims for water recycling to battle drought

California is currently in the thralls of a three-year drought that is the worst in the state’s history. The crisis leads to an increased focus on water recycling in southern California. The municipality is already home to the largest water recycling plant in the world that turns water sourced Read More...
