In desert trials, next-generation water harvester delivers fresh water from air

Posted by in categories: energy, habitats, sustainability

Last October, a University of California, Berkeley, team headed down to the Arizona desert, plopped their newest prototype water harvester into the backyard of a tract home and started sucking water out of the air without any power other than sunlight.

The successful field test of their larger, next-generation harvester proved what the team had predicted earlier in 2017: that the harvester can extract drinkable water every day/night cycle at very low humidity and at low cost, making it ideal for people living in arid, water-starved areas of the world.

“There is nothing like this,” said Omar Yaghi, who invented the technology underlying the harvester. “It operates at ambient temperature with ambient sunlight, and with no additional energy input you can collect water in the desert. This laboratory-to-desert journey allowed us to really turn water harvesting from an interesting phenomenon into a science.”

India Increases Its Massive 2022 Renewable Energy Target

Posted by in categories: solar power, sustainability

For the last several years, CleanTechnica has covered renewable energy development in India quite closely. Several years ago, India set what seemed like a lofty target of 175 gigawatts of wind and solar energy by March 2022. Few believed that was a practical target, but then India plowed forward and happily impressed the world. This week that goal was increased to 227 gigawatts!

Currently, India has added a little more than 70 gigawatts of that goal. Assessing the progress to date on a linear scale, the trend would seem to indicate the country is behind. However, renewable energy growth is not linear.

Berkeley’s desert water extractor is taking us one step closer to harvesting water out of thin air

Posted by in categories: energy, sustainability

Right now, there are roughly 16 sextillion liters of water suspended in the atmosphere. The air around you is a river, you just can’t see it.

Harvesting water from air would be a game-changing solution to tackling freshwater scarcity, which is increasing as the world warms. It would be especially vital in places with very little humidity in the air, like the desert. But while it’s technically possible—you just need to get the water content in the air to condense around something—doing so efficiently has been difficult, until now.

The challenge with this technology is cooling. Water vapor will only condense into a liquid if the material it condenses on is cooler than the surrounding air. That’s why droplets of condensation will appear on a soda can the moment you take it out of the fridge. But how do you leave a piece of machinery in the desert sun all day and keep it cooler than the surrounding air? One way would be to install a cooling system. But it takes a a lot of energy to perpetually cool an object in a hot place, and isn’t feasible in places where energy is expensive. We also don’t want to increase the amount of energy demand in a world already struggling to reduce emissions.

NASA Publishes SpaceX’s Proposal for a Futuristic Kennedy Space Center

Posted by in categories: Elon Musk, space travel, sustainability

The Kennedy Space Center might be getting a major upgrade and expansion soon if Elon Musk gets his way. NASA published a plan submitted by SpaceX that dramatically reimagines the company’s presence at KSC in Cape Canaveral, Florida. The plans include everything from a control tower that resembles a flying saucer to a “rocket garden,” showcasing futuristic designs that will expand the space company’s footprint and potential influence within the US agency.

NASA published a draft environmental review for the proposed SpaceX Operations Area, as first reported by Florida Today on Friday. According to the document, SpaceX is seeking permission to build on a 67-acre patch of land about one mile north of KSC’s visitor center complex.

SpaceX wants to build a 133,000-square-foot Falcon hangar to process the used boosters and other rocket materials that it recovers. The hangar would facilitate more efficient recycling of the materials which could potentially save the company billions of dollars per launch.

The decline of our oceans is accelerating, but it’s not too late to stop it

Posted by in categories: economics, energy, sustainability

We shouldn’t underestimate the powerful attraction of a ‘sustainable blue economy’, which – I firmly believe – will feed and support the lives of our children and those who come after them. Getting it right – whether through aquaculture, offshore energy, green shipping or ecotourism – is vital not just for SDG14, but for the future of the global commons, and for humankind itself. To do this we must move with purposeful steps. Here are five that could be taken immediately.

Curtail subsidies

Let us stop throwing good money after bad, and resolve to prohibit subsidies that support harmful and illegal fishing. A critical opportunity to eliminate them is looming at the 2019 ministerial meeting of the World Trade Organisation. It must not be missed.

Under the sea, Microsoft tests a datacenter that’s quick to deploy, could provide internet connectivity for years

Posted by in categories: internet, robotics/AI, sustainability

Microsoft is leveraging technology from submarines and working with pioneers in marine energy for the second phase of its moonshot to develop self-sufficient underwater datacenters that can deliver lightning-quick cloud services to coastal cities. An experimental, shipping-container-size prototype is processing workloads on the seafloor near Scotland’s Orkney Islands, Microsoft announced today.

The deployment of the Northern Isles datacenter at the European Marine Energy Centre marks a milestone in Microsoft’s Project Natick, a years-long research effort to investigate manufacturing and operating environmentally sustainable, prepackaged datacenter units that can be ordered to size, rapidly deployed and left to operate lights out on the seafloor for years.

“That is kind of a crazy set of demands to make,” said Peter Lee, corporate vice president of Microsoft AI and Research, who leads the New Experiences and Technologies, or NExT, group. “Natick is trying to get there.”

This Smartphone Pioneer Is Fighting to Create a Transhumanist Superdemocracy

Posted by in categories: mobile phones, robotics/AI, sustainability, transhumanism

It’s a philosophy best exemplified by Wood’s book released last month, Transcending Politics: A Technoprogressive Roadmap to a Comprehensively Better Future, which starts by declaring politics “broken,” technology as something that “risks making matters worse,” and deems transhumanism the force that can fix it all “comprehensively”:


David Wood, a transhumanist who co-founded Symbian in 1998, is working to develop a transhumanist superdemocracy that uses the best parts of artificial intelligence and communication to draw on the likes of Zoltan Istvan and Peter Thiel in a new movement to create longevity and sustainable abundance for all.

Europe is building more wind and solar — without any subsidies

Posted by in categories: energy, sustainability

In the United States, the energy market dynamics are quite different. There is less top-down pressure to deploy renewables in the US, and the main support comes in the form of tax credits on the back end rather than feed-in tariffs or other subsidies on the customer-facing side. These subsidies are applied across the industry and not through a competitive bidding process. As a result, there isn’t as strong a push to get the industry off the incentives that are available.

But one element of the American renewable energy experience is gaining ground in Europe, namely the use of power purchasing agreements (PPAs) with utilities to buy electricity at a fixed price for years at a time.

PPAs are far less common in Europe than in the United States, but some of these new unsubsidized renewable energy projects are counting on them.
