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.

Scientists from Nanyang Technological University, Singapore (NTU Singapore) have devised an efficient method of recovering high-purity silicon from expired solar panels to produce lithium-ion batteries that could help meet the increasing global demand to power electric vehicles. High-purity silicon makes up the majority of solar cells, yet they are typically discarded at the end of their operational lifespan after 25 to 30 years. It is challenging to separate the silicon from other solar cell components such as aluminium, copper, silver, lead, and plastic. Moreover, recycled silicon has impurities and defects, making it unsuitable for other silicon-based technologies. Existing methods to recover high-purity silicon are energy-intensive and involve highly toxic chemicals, making them expensive and limiting their widespread adoption among recyclers.

Australian community battery program cuts power bills and strengthens the grid

Australia’s community battery programme is reducing household electricity bills, cutting greenhouse gas emissions, and bolstering the national grid, policymakers and analysts say.

Under the Community Batteries for Household Solar scheme, which has A$200 million (US$133 million) in state grant funding at its disposal, 400 batteries are being installed in neighbourhoods across the country. Up to 100,000 households will have access to these facilities, allowing them to store excess solar energy for use during peak times — typically in the mornings and evenings.

The programme is aimed, in part, at encouraging more households to install rooftop solar systems. It will also allow households that can’t install solar panels or their own batteries to access clean energy, and will reduce the country’s reliance on costly and polluting gas peaker plants.

While still a relatively new concept, the benefits are starting to show up.

The Solar Saga

So….. This post has been a long time coming.

NO, IT'S NOT BAD, I SWEAR!

This is the final post of the Solar Panel Saga, a grueling process which took far longer than it should.

SO.

Let us.

BEGIN!

For those of you that do not know, I'm homeless, living in a van. Not by choice, but hey, what can you do?

As a normal adult in the 21st century, I need power.

As a normal adult in a van from 1998, I can't rely on the engine to do it. So I had been thinking of something like this even since I first ended up homeless. but I believed all the solutions for this were impossibly expensive.

then, in February 2024, I found the BOX!

for just ten dollars plus shipping, I could control a solar panel. it seemed like magic! like a Sign! so I purchased it. Along with what proved to me a dramatically inadaquate solar panel, although I didn't know that at the time.

this led eventually to the search for a batter system that would work, and I already had the perfect idea in mind.

in my local (unnamed for legal reasons) big box store, in the marine section, was a battery box with a built-in system of outlets. TWO 12v DC automotive ports! TWO USB Connections! one USB-C and one USB-A! a BREAKER! and a HIGH-POWER EXTERNAL WING NUT CONNECTION DIRECTLY TO THE BATTERY!!!

It was perfect. and only 30ish bucks. the problem, was the battery.

Batteries are expensive. the battery I needed was a Deep Cycle battery, a type of lead-acid battery designed for long charge and discharge cycles. such a battery is a fairly niche item. I didn't and in fact couldn't find one in my big box store. so. I waited for my next paycheck, and went in search of a battery.

turns out ten seconds of googling found a battery store, like, a half mile from my usual parking spot. lol.

with much consternation and a great deal of money ($160is all told) I had my battery. Extensive testing would confirm its functioning in the box.

Now, a PANEL!

In days of Old, when Men were Bold, and whiskey was far, FAR cheaper: solar panels sucked. and were really expensive. when last I had looked into the idea a decade or more before, the best panels were hundreds to thousands of dollars and, while they generated useful power, were finicky about light conditions. then I discovered Mono-Crystal panels, and was amazed. 50 watts for 64 dollars. just over a dollar a watt. larger panels were even cheaper: 1000w of panels came to barely $800! incredible! said I, this would be no problem at all! Until i membered. I'm homeless.

Fuck.

While technically I have a mailing address, that address is at a homeless support place (where you can shower, and do laundry, and get meals, rather than sleep), which is infamous for questionable support staff, long wait times, and not the best service in the world. so.

Shipping a large, expensive, fragile piece of equipment there was a no-go.

then I saw the hardware store I was buying it from had ship to store.

YAY, COVID! (bout the only good thing to come from the Plague. or maybe before? idk.)

So I shipped it there, picked it up, and now was the time to Mount it to the roof!

And this, is where my troubles Truly Began.

At first, I thought to magnet the thing to the roof, so I bought some magnets.

NOPE!

Fiberglass

Then I thought to screw it in.

NOPE!

Couldn't get a drill in the panel

Suction cup?

NOPE!

not strong enough

Glue?

NOPE!

Wasteful, infective, and long cure time

fuck the whole business?

NOPE!

Still need power!

So. after weeks of waiting for money and days off to try shit, I decided on a plan:

Get some Plywood Glue it to the roof get some metal glue it to the board magnet panel to metal.

easy, simple, I need a stepladder, but I can just go to the hardware store, buy then return one. so I got to work.

the glue didn't hold the metal. or the wood very well, for that mater.

so, I relented, bought some screws, a drill, and some drill bits, and on the evening of May 28, 2024, finally saw my dream of solar power through.

it's the end of June now, and my little panel has done well. the metal is rusted orange, the wood is curved and warped, the magnets hold steady, and duct tape keeps the wires out of the doors.

But.

I'm typing this on a laptop powered by solar. and that's Damn Good.

The Panel, Herself.

I’m poor, Homeless, and jobless, please give me money, so I don't starve!

"Big batteries are muscling gas out of California’s electricity mix, according to data collated by Stanford University Professor Mark Z. Jacobson.

In the 100 days to June 14, California saw a 45% reduction in gas-fired power output, relative to the same period a year before.

The decline was mostly thanks to a surge in battery installations in recent months. The state now has 10.4 gigawatts (GW) of battery storage capacity — a technology it says is key to achieving a 100% clean electricity system by 2045.

Batteries are used to store energy from renewable sources like solar during the day so that it can be deployed in the evening, when solar generation tapers off and demand for power surges. These facilities are increasingly challenging the role of gas plants in meeting peak demand.

On the evening of June 10, for example, big batteries injected a record 7.7GW of instantaneous power into California’s grid. They accounted for a quarter of total electricity supply at that point.

And according to data from GridStatus, gas generation on an average April day in California hit a seven-year low, reversing an earlier trend that had been fuelled by rising electricity demand.

On 89 of the 100 days to June 14, there were periods where renewables generated more than enough electricity to cover all of California’s needs. This excess energy creates a strong business case for batteries, which can charge up when prices are low and discharge when prices are high.

Compared to a year before, utility-scale solar output was up 32% over the 100-day period, wind generation grew 10%, and battery output doubled, Jacobson says. Meanwhile, demand for electricity from the grid was down 3% due to new rooftop solar installations."
