Comments Off on Researchers develop solar-powered device to harvest water in the desert

A solar-powered device could make water worries a thing of the past. Nine scientists from the Massachusetts Institute of Technology (MIT), King Abdulaziz City for Science and Technology , and University of California, Berkeley designed a water harvester that can pull water from air even if humidity is just 20 percent. Chemist Omar Yaghi of UC Berkeley said, “We wanted to demonstrate that if you are cut off somewhere in the desert , you could survive because of this device.” Yaghi invented compounds known as metal-organic frameworks (MOFs) 20 years ago, and now is using MOF crystals to harvest water even in dry places. In the water harvesting device, around two pounds of tiny MOF crystals are compressed between a solar absorber and condenser plate to collect around 0.7 gallons of water in 12 hours.

Yaghi said, “A person needs about a [330ml] can of water per day. That is something one could collect in less than an hour with this system.” Right now there’s no other way to harvest water in low humidity except to draw on extra energy , according to Yaghi. “Your electric dehumidifier at home ‘produces’ very expensive water,” he says. In contrast sunlight enables the new device to work. Rooftop tests at MIT have already demonstrated the device works in the real world. Even if you never find yourself stranded in the desert, you could benefit from such a water harvester. “One vision for the future is to have water off-grid , where you have a device at home running on ambient solar for delivering water that satisfies the needs of a household,” said Yaghi. “To me, that will be made possible because of this experiment. I call it personalized water.” Science published the team’s research yesterday .

The Cloud Harvester Catches and Stores Fresh Water from Fog

Comments Off on The Cloud Harvester Catches and Stores Fresh Water from Fog

The Cloud Harvester is an ingenious device that is designed to catch and condense fog into water droplets which, in turn, run down a stainless steel mesh into a water storage container. The device represents a quantum leap in water collection efficiency, and it’s ideally suited for poor, rural, mountainous, coastal regions with little freshwater resources or infrastructure. It is almost as efficient as existing fog-harvesting devices that are currently on the market, but it is much smaller and more cost-efficient to produce and transport.

Comments Off on The Obama Administration Proposes $8 Billion in Loans for ‘Clean’ Fossil Fuel Technologies

Coal photo from Shutterstock By now, Inhabitat readers know that ‘ clean coal ‘ is a contradiction of terms. However, as part of President Obama’s new energy initiative , the U.S. Department of Energy has proposed $8 billion in loan guarantees for fossil fuel technologies to reduce the country’s greenhouse gas emissions . The proposal would fund schemes such as waste heat recovery and carbon dioxide capture , however it has unsurprisingly received criticism as it would draw focus away from green technology projects such as renewable energy and electric vehicles .
