I was applying for a lil Art show that goes in conjunction with a Texas glass conference I am presenting at later this year when I realized that I dont actually have any edited photos of the Big Cobalt Sunset Eclipse Sphere I made last year.

A few minutes in GIMP fixed that. Here are two that make it look a little rounder than it really is.

Doubtful that they will have the shipping budget... but also doubtful that they will be able to find something quite like it. Who knows, a Fort Worth business might really like it? The piece is inspired by the eclipse that want through there last year... and those beautiful Texas Sunsets.

This piece can currently be seen (partially) LIVE at this link

As part of a server sculpture I am actively developing for an upcoming show.

Kyiv delayed #MineralsDeal to let Trump take credit

In bid to secure #Trump's support Ukrainian govt appealed to Trump’s #ego

Ukraine's home to huge deposits of critical minerals, including #cobalt, #graphite, #lithium, planned to sign deal with Biden. #US Senators Graham & Blumenthal announced plans for the deal in August 2024

#Ukrainian authorities then twice delayed signing agreement

Delay is opportunity for Trump to claim victory at start of term

So I think I should share "Media" right away so folks know it's really moi - how about a rock? This "rock" is one of my more "famous" rock photos. I took it in a glass display case at the Tucson Gem and Mineral Show years ago in 2007 with a point and shoot camera. The "rock" is an amazing geode from the Bisbee mines and owner called it "Velvet Beauty". Back then it was valued at $25,000. I have thousands of photos on my flickr account that is now about 20 years old. Yikes! #Cobalt #Rock #Azurite #Geode

Bacteria helping to
❇️extract rare metals from old batteries
❇️in boost for green tech

Scientists have formed an unusual new alliance in their fight against climate change -- 🔥They are using #bacteria to help them extract #rare #metals vital in the development of green technology.

🆘 Without the help of these microbes, we could run out of raw materials to build turbines, electric cars and solar panels, they say.

The work is being spearheaded by scientists at the University of Edinburgh and aims to
👉 use bacteria that can extract lithium, cobalt, manganese and other minerals from old batteries and discarded electronic equipment. 👈

These scarce and expensive metals are vital for making electric cars and other devices upon which green technology devices depend -- a point stressed by Professor Louise Horsfall, chair of sustainable biotechnology at Edinburgh.

“If we are going to end our dependence on petrochemicals and rely on electricity for our heating, transport and power, then ⭐️we will become more and more dependent on metals,” said Horsfall.

“All those photovoltaics, drones, 3D printing machines, hydrogen fuel cells, wind turbines and motors for electric cars require metals – many of them rare – that are key to their operations.”

♦️Politics is also an issue, scientists warn.
#China controls not only the main supplies of rare earth elements, but dominates the processing of them as well.

“To get around these problems we need to develop a #circular #economy where we #reuse these minerals wherever possible, otherwise we will run out of materials very quickly,” said Horsfall.

⚠️“There is only a finite amount of these metals on Earth and we can no longer afford to throw them away as waste as we do now.

We need new #recycling technologies if we want to do something about global warming.”

And the key to this recycling was the microbe, said Horsfall.
“#Bacteria are wonderful, little crazy things that can carry out some weird and wonderful processes. Some bacteria can synthesise nanoparticles of metals, for example.

We believe they do this as a detoxification process. Basically they latch on metal atoms and then they spit them out as nanoparticles so that they are not poisoned by them.”

✅ Using such strains of bacteria, Horsfall and her team have now taken waste from electronic batteries and cars, dissolved it and then used bacteria to latch on to specific metals in the waste and deposit these as solid chemicals.

“First we did it with #manganese. Later we did it with #nickel and #lithium. And then we used a different strain of bacteria and we were able to extract #cobalt and nickel.”

#Oxygen discovery defies knowledge of the deep ocean

Victoria Gill, Science correspondent, BBC
July 22, 2024

"Scientists have discovered '#DarkOxygen' being produced in the #DeepOcean, apparently by lumps of metal on the #seafloor.

"About half the oxygen we breathe comes from the #ocean. But, before this discovery, it was understood that it was made by marine plants photosynthesising - something that requires sunlight.

"Here, at depths of 5km, where no sunlight can penetrate, the oxygen appears to be produced by naturally occurring metallic '#nodules' which split seawater - H2O - into hydrogen and oxygen.

"Several #mining companies have plans to collect these nodules, which marine scientists fear could disrupt the newly discovered process - and damage any marine life that depends on the oxygen they make.

"'I first saw this in 2013 - an enormous amount of oxygen being produced at the seafloor in complete darkness,' explains lead researcher Prof Andrew Sweetman from the Scottish Association for Marine Science. 'I just ignored it, because I’d been taught - you only get oxygen through #photosynthesis.

"'Eventually, I realised that for years I’d been ignoring this potentially huge discovery,' he told BBC News.

"He and his colleagues carried out their research in an area of the deep sea between #Hawaii and #Mexico - part of a vast swathe of seafloor that is covered with these metal nodules. The nodules form when dissolved metals in seawater collect on fragments of shell - or other debris. It's a process that takes millions of years.

"And because these nodules contain metals like #lithium, #cobalt and #copper - all of which are needed to make batteries - many mining companies are developing technology to collect them and bring them to the surface.

"But Prof Sweetman says the dark oxygen they make could also support life on the seafloor [and life on Earth!]. And his discovery, published in the journal Nature Geoscience, raises new concerns about the risks of proposed deep-sea mining ventures.

"The scientists worked out that the metal nodules are able to make oxygen precisely because they act like batteries."

Scaling up critical minerals supply in time to meet rising needs is essential to the success of #batteries

In one Scenario, demand for critical minerals for batteries expands rapidly by 2030,
with #manganese, #lithium, #graphite and #nickel increasing at least sixfold, and #cobalt more than tripling.

While this requires new mining and refining, innovation on chemistries, enhanced recycling and “right-sizing” of batteries can cut demand for critical minerals

"The recent price cuts come from a deliberate decision to use abundant earth materials such as iron and phosphorus wherever possible.

These #batteries are cheaper, as they have no #cobalt. They have other benefits too: a longer usable life and less risk of fire than traditional #lithium battery chemistries. The downside is they have lower capacity and voltage."

The ConversationA battery price war is kicking off that could soon make electric cars cheaper. Here’s howChina’s two largest EV battery makers are pledging to slash the cost of their batteries this year. Behind the pledge is a cost war – and new battery chemistries.

The US, unable to build long-distance rail at home, is going to construct a 1200 mile rail line to cart minerals out of DR Congo and Zambia out to the coast of Angola.

I see.

If I were these countries I would insist on making the batteries and magnets locally, then getting the value added income. Why consent to be plundered, once again?
