The water footprint of solar power may rarely come to mind. It should because cleaning the dust off of photovoltaic panels requires hundreds of millions of gallons of water per year. In a bid to come up with a solution, MIT scientists have recently invented an alternative … [Read more...] about This is how we could clean our solar panels without water

This solar-powered desalination system is a gamechanger
Desalination offers a lot of promise to communities that may face water scarcity in the future. For some, the problem is compounded by the potential scarcity of reliable electricity. As such, it has been the aim of many researchers to develop solar-powered desalination devices, … [Read more...] about This solar-powered desalination system is a gamechanger
How coal could help desalinate seawater in an eco-friendly way
While the practice of burning coal to generate electricity is soon to become a thing of the past, the material could prove useful in other, more sustainable ways. A new study, for example, has shown that the mineral could find use in the desalination of seawater. The study, … [Read more...] about How coal could help desalinate seawater in an eco-friendly way
Alphabet makes its low-cost water harvester open-source
According to WHO/UNICEF, about a third of the global population doesn’t have access to safe drinking water. More than half of these people, however, live in areas with just the right climate conditions to enable special water harvesting technologies to provide clean drinking … [Read more...] about Alphabet makes its low-cost water harvester open-source
