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.

This is a The MITCHELLS vs the MACHINES mega posts. This is all of the paintings, sketches and rough keys I did for locations in the “robots take over the world” and “turn off the wifi” montages. Some of these are done in half the afternoon, some take 3-4 days. We had to make these cheaply since it’s so many one of locations for these montages. It’s wire having to find the balance of cartooning a place so it’s immediately recognizable and leaning into tropes and stereotypes. Always something to work on.
1. Rome, painted over re-use 3d models
2. Paris over re-use 3d
3. Golden Gate Bridge !
4. This was Melbourne but I think it became Toronto in the final film. Lots of 3d and photo collage in this one
5.Shanghai, was cut from the movie (can you guess why)
6. Japan, color key for a shot that only made it into a trailer. Silly toilet gag by my friend Garrett lee
7. Taj Mahal , India.
8. Rio, rough paint over 3d. This was chat because it was so dark to have people driving off the cliff lol
9. Taj Mahal alt sketch
10. Rough Mexico paint over reuse 3d. Wish I had put more work into the signage, yikes

Cerveceria Wendlandt Mexi Hazy IPA (Picked up at Total Wine). A 3 of 4. Smells of orange citrus and some faint stone fruit, and has a medium body with some smoothness to it. Quite well-balanced with very little bitterness and lots of fruit in the nose and up front.

Reddit admins, led by CEO "u/spez", tried to run its previously-popular "place" experiment again to distract users from unpopular opinions. Reddit users made their opinion on the matter clear.
If you have a reddit account and want to contribute, help us keep the pride flags in the "P" clean — and maintain a three-black-pixel border between the flags and the red lines below.

following up to my original post for “vostok” (the antarctic mermaid and the pinned post—the dtiys for that goes all the way to may 1, too!), i give you my prompts for mermay around the world. i tried to get all the continents—it’s tricky here with the states because we’re such a melting pot of cultures and dialects, so i picked two of the cities i can readily represent through art (i was going to use new orleans or nashville but i’m slightly more drawn to vegas and hawai’i).
this is inspired by three things:
planetary coalition (the obvious one).
some time ago, i was looking into art of the middle east, namely israel and iran (before the revolution of 1979, of course) and feeling enamored by it all.
the third thing that inspired it was thinking about east asian art and how i’ve always been drawn to it. i don’t know how my mind jumped to it but i thought about angkor wat and block paintings of temples in southeast asia, and my mind being the rocket it is went from there.
***i also don’t want to hear any objections to tel aviv and kiev being on here. if you don’t like it, do your own or use someone else’s list.
i’m dropping these now to give plenty of time to study the art and culture of each city. i’d rather let people be influenced and inspired than appropriate 😉

Part 2! Once again arranged in alphabetical order.
I sent an AI generator the prompt: “if [country name] was a person, painted in the style of [artist(s) of the same country]”
Thanks @amaranth-aether for the suggestions of Croatia and Portugal!
EDIT: After some discussion with a fellow fan, it’s been brought to my attention that I failed to recognize the fact that several of the portraits I’ve featured (particularly those of East Asian Women) can be hurtful due to their whitewashed features, and could reinforce whitewashed stereotypes with other viewers who are unaware of the issue.
This series started as an experiment to learn how the AI works, and over time I have become very aware that this AI has had very whitewashed “training” for its algorithm, particularly for portraits. However, in my excitement over the possibilities for future prompts, I failed to register those problems and additionally failed to consider the negative impact of sharing the portraits publicly, especially with no acknowledgement of the AI’s biases. I apologize to anyone who was hurt by any of these images, and would encourage everyone to learn more about the embedded biases of AI generators by reading articles like this one from Vice or this one from Science.

A mother’s legacy.The sweetest, the most precious flower. Black gold.  They are spices whose owners hold them most dearly.
Finally, I finish the spices-themed hetalia/nyotalia fanart stuff! Now they become a set! 
The first one is 18th-century teenage Nyo Mexico, smelling vanilla flowers while holding a vanilla pod and shedding a tear, because vanilla reminds her of her mother(Aztecs/Mexica) since vanilla is native to Mesoamerica and Mexica consumed it. The second one is nyo Indonesia and her clove.The third one is nyo India and her black pepper.
I also have drawn chibi versions because why not:
