Scientists have developed a new solar-powered system to convert saltwater into fresh drinking water which they say could help reduce dangerous the risk of waterborne diseases like cholera.

Via tests in rural communities, they showed that the process is more than 20% cheaper than traditional methods and can be deployed in rural locations around the globe.

Building on existing processes that convert saline groundwater to freshwater, the researchers from King’s College London, in collaboration with MIT and the Helmholtz Institute for Renewable Energy Systems, created a new system that produced consistent levels of water using solar power, and reported it in a paper published recently in Nature Water.

It works through a process called electrodialysis which separates the salt using a set of specialized membranes that channel salt ions into a stream of brine, leaving the water fresh and drinkable. By flexibly adjusting the voltage and the rate at which salt water flowed through the system, the researchers developed a system that adjusts to variable sunshine while not compromising on the amount of fresh drinking water produced.

Using data first gathered in the village of Chelleru near Hyderabad in India, and then recreating these conditions of the village in New Mexico, the team successfully converted up to 10 cubic meters, or several bathtubs worth of fresh drinking water. This was enough for 3,000 people a day with the process continuing to run regardless of variable solar power caused by cloud coverage and rain.

[Note: Not sure what metric they're using to calculate daily water needs here. Presumably this is drinking water only.]

Dr. Wei He from the Department of Engineering at King’s College London believes the new technology could bring massive benefits to rural communities, not only increasing the supply of drinking water but also bringing health benefits.

“By offering a cheap, eco-friendly alternative that can be operated off the grid, our technology enables communities to tap into alternative water sources (such as deep aquifers or saline water) to address water scarcity and contamination in traditional water supplies,” said He.

“This technology can expand water sources available to communities beyond traditional ones and by providing water from uncontaminated saline sources, may help combat water scarcity or unexpected emergencies when conventional water supplies are disrupted, for example like the recent cholera outbreaks in Zambia.”

In the global rural population, 1.6 billion people face water scarcity, many of whom are reliant on stressed reserves of groundwater lying beneath the Earth’s surface.

However, worldwide 56% of groundwater is saline and unsuitable for consumption. This issue is particularly prevalent in India, where 60% of the land harbors undrinkable saline water. Consequently, there is a pressing need for efficient desalination methods to create fresh drinking water cheaply, and at scale.

Traditional desalination technology has relied either on costly batteries in off-grid systems or a grid system to supply the energy necessary to remove salt from the water. In developing countries’ rural areas, however, grid infrastructure can be unreliable and is largely reliant on fossil fuels...

“By removing the need for a grid system entirely and cutting reliance on battery tech by 92%, our system can provide reliable access to safe drinking water, entirely emission-free, onsite, and at a discount of roughly 22% to the people who need it compared to traditional methods,” He said.

The system also has the potential to be used outside of developing areas, particularly in agriculture where climate change is leading to unstable reserves of fresh water for irrigation.

The team plans to scale up the availability of the technology across India through collaboration with local partners. Beyond this, a team from MIT also plans to create a start-up to commercialize and fund the technology.

“While the US and UK have more stable, diversified grids than most countries, they still rely on fossil fuels. By removing fossil fuels from the equation for energy-hungry sectors like agriculture, we can help accelerate the transition to Net Zero,” He said.

A German-American research team has discovered two highly unusual bacterial species in the tissue of two deep-sea corals from the Gulf of Mexico. These previously unknown coral symbionts have an extremely reduced genome and lack the ability to obtain energy from carbohydrates, the team reports in an article published in the journal Nature Communications. The team was led by Professor Iliana Baums from the Helmholtz Institute for Functional Marine Biodiversity at the University of Oldenburg (HIFMB) and Dr. Samuel Vohsen from Lehigh University in the U.S. "These species are impressive examples of how few genes are needed for a functional organism," says Baums.

Researchers present new diagnostic tool for laser-plasma accelerator using metal foil as 3D scanner

Laser-plasma accelerators take up less space than conventional facilities, which are sometimes kilometers long. Such compact particle sources can accelerate electron bunches efficiently, enabling X-ray lasers that fit in the basement of a university institute. But there are a few challenges to be met: in order to produce UV or X-ray light, the electron bunches generated by a laser-plasma accelerator must be very finely bundled and have defined properties. To date, it has been difficult to even measure these bunches precisely. Now, a team at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has developed a novel measuring method that should help to drive the development of laser-plasma acceleration.

Traditional desalination technology has relied either on costly batteries in off-grid systems or a grid system to supply the energy necessary to remove salt from the water. In developing countries’ rural areas, however, grid infrastructure can be unreliable and is largely reliant on fossil fuels.

Creating a low-cost ‘battery-like’ desalination technology removes the reliance on battery technology for using intermittent solar energy in off-grid applications, enabling affordability to rural communities in developing countries like India.

“By removing the need for a grid system entirely and cutting reliance on battery tech by 92%, our system can provide reliable access to safe drinking water, entirely emission-free, onsite, and at a discount of roughly 22% to the people who need it compared to traditional methods,” He said.

“While the US and UK have more stable, diversified grids than most countries, they still rely on fossil fuels. By removing fossil fuels from the equation for energy-hungry sectors like agriculture, we can help accelerate the transition to Net Zero,” He said.

“The next step for us is to apply this low-cost technology to other sectors, including wastewater treatment, and producing alkaline to make the ocean more alkaline to help it absorb more CO2 from the atmosphere. By taking this approach not only can we decarbonize agriculture, but wider environmental and climate benefits as well.”

This story originally appeared in Hakai Magazine and is part of the Climate Desk collaboration.

In the Fram Strait off Greenland’s west coast, Véronique Merten encountered the foot soldiers of an invasion.

Merten was studying the region’s biodiversity using environmental DNA, a method that allows scientists to figure out which species are living nearby by sampling the tiny pieces of genetic material they shed, like scales, skin, and poop. And here, in a stretch of the Arctic Ocean 400 kilometers north of where they’d ever been seen before: capelin.

And they were everywhere.

The small baitfish found in the northern Atlantic and Pacific Oceans is an ardent colonizer. Whenever the ocean conditions change, it’s really easy for capelin to expand their range, says Merten, a marine ecologist at the GEOMAR Helmholtz Centre for Ocean Research Kiel in Germany.

It is difficult to estimate an animal’s abundance based solely on the amount of its DNA in the water. Yet in Merten’s samples, capelin was the most frequently encountered species—far more than typical Arctic fish like Greenland halibut and Arctic skate. To Merten, the evidence of so many capelin so far north is a bold sign of a worrying Arctic phenomenon: Atlantification.

The Arctic Ocean is warming quickly—the Fram Strait is nearly 2 °C warmer than it was in 1900. But Atlantification is about more than rising temperatures: it’s a process that is reshaping the physical and chemical conditions of the Arctic Ocean.

Because of the oceans’ global circulation patterns, water routinely flows from the Atlantic into the Arctic. This exchange mostly occurs in deeper water, with currents carrying warm and relatively salty Atlantic water north. This warm Atlantic water, however, doesn’t mix well with the Arctic’s surface water, which is relatively cool and fresh. Fresher water is less dense than saltier water, so the Arctic water tends to float on top, trapping the saltier Atlantic water deep below the ocean’s surface.

As sea ice disappears, however, the surface of the Arctic Ocean is heating up. The barrier between the layers is degrading and Atlantic water is mixing more easily into the upper layer. This is kicking off a feedback loop, where warmer surface water melts more sea ice, further exposing the ocean’s surface to sunlight, which heats the water, melts the ice, and allows Atlantic and Arctic water to blend even more. That’s Atlantification: the transformation of the Arctic Ocean from colder, fresher, and ice-capped to warmer, saltier, and increasingly ice-free.

Merten’s discovery of abundant capelin in the Fram Strait—as well as the DNA she found from other Atlantic species, like tuna and cock-eyed squid, far outside their typical range—is further proof of just how quickly Atlantification is playing out. And its consequences could be enormous.

In the Barents Sea off Russia, for example, a long-term study presents a grim picture of how Atlantification can disrupt Arctic ecosystems. As the Barents Sea has grown warmer and saltier, Atlantic species have been “moving in and taking over,” says Maria Fossheim, a fisheries ecologist with the Institute of Marine Research in Norway who led that study.

Fish communities in the Barents Sea, Fossheim says, have shifted north 160 kilometers in just nine years—“three or four times the pace that [previous studies] had foreseen.” By the end of her study, in 2012, Fossheim found that Atlantic species had expanded throughout the Barents Sea, while Arctic species were mostly pushed out.

Merten’s findings suggest the Fram Strait may be heading in a similar direction. Because this study is the first to examine the diversity of fish in the Fram Strait, however, it is unclear how recent these changes really are. “We need these baselines,” Merten says. “It could be that [capelin] already occurred there years ago, but no one ever checked.”

Either way, they’re there now. The question is: what will show up next?

Chemical cocktail from plastics: Pilot study describes degradation and leaching process of plastic consumer products

Plastic waste in rivers and oceans is constantly releasing chemicals into the water. Until now, it was unknown how large these quantities are and which substances are released particularly strongly. In the large-scale P-LEACH project, experts from four research institutes of the Helmholtz Association have now analyzed the composition and concentrations of many different substances. The main focus was on the question of how the sun's UV radiation increases the release of chemicals. Hundreds of thousands of tons of plastic waste are floating in rivers and oceans. The impact of waves, the sun's UV radiation and salty seawater cause the plastic to gradually break down into smaller and smaller fragments and ultimately float in the oceans as tiny microplastic particles. In numerous studies, researchers have investigated the extent to which marine animals ingest these particles and whether they become ill from them. Far less well researched to date is how the ingredients of various plastic products—including additives such as heavy metals, flame retardants, plasticizers, dyes and many other ingredients, that give plastic its versatile properties—affect marine life.
