“Thiel, a co-founder of #Palantir and #PayPal, said: “The future demands more compute than we can imagine. Extraterrestrial solutions are no longer science fiction. #Panthalassa has opened the ocean frontier.”
The company’s “nodes” stand almost as tall as Big Ben in London or New York’s Flatiron Building. Most of the 85-metre-long solid-steel structure sits below the surface, including a hermetically sealed container holding the #AIServer, cooled by #seawater.
The vessels can drive themselves to their destination, using the shape of their hull to propel themselves through the #waves without an engine.”
Nothing, not the land, air or sea escapes the oligarch’s quest for wealth.

I once read that the #UAE were completing one one every year.
That was before Covid struck, through...but acc. 2 wiki:"The UAE relies on desalination for approximately 42% of its drinking water and hosts more *than 70 desalination plants* across the country. Most recent projects increasingly favor reverse osmosis (#RO) technology over traditional multi-stage flash (#MSF) distillation,... continues to...add 240 million imperial gallons per day using #seawater

#SodiumIonBatteries offer an alternative to tricky #lithium
Oct 26th 2023
Excerpt: "Fortunately, lithium is not the only game in town. As we report this week, a clutch of firms are making batteries based on sodium, lithium’s elemental cousin. Since sodium’s chemical properties are very similar to those of lithium, it too makes for good batteries. And sodium, which is found in the salt in #seawater, is thousands of times more abundant on Earth than lithium and cheaper to get at. Most of the companies using sodium to make batteries today are also Chinese. But pursuing the technology in the West might be a surer route to energy security than relying heavily on lithium.
"Besides its abundance, sodium has other advantages. The best lithium batteries use #cobalt and #nickel in their electrodes. Nickel, like lithium, is in short supply. #Mining it on land is #EnvironmentallyDestructive. Proposals to grab it from the #seabed instead have caused rows. A good deal of the world’s cobalt, meanwhile, is extracted from small mines in the #DemocraticRepublicOfCongo, where #ChildLabour is common and working conditions are dire. Sodium batteries, by contrast, can use #electrodes built from #iron and #manganese [and wood #lignin], which are plentiful and uncontroversial. Since the chemical components are cheap, a scaled-up industry should be able to produce batteries that cost less than their lithium counterparts.
"Sodium is not a perfect replacement for lithium. It is heavier, meaning sodium batteries will weigh more than lithium ones of an equivalent capacity. That is likely to rule them out in some cases where lightness is paramount. But for other applications, such as #GridStorage or #HomeBatteries, weight is irrelevant. Several Chinese carmakers are even beginning to put sodium batteries in #ElectricVehicles."

New #SodiumIon battery stores twice the energy and #desalinates #seawater
Date: February 19, 2026
Source: University of SurreySummary: A surprising breakthrough could help sodium-ion batteries rival lithium—and even turn seawater into drinking water. Scientists discovered that keeping water inside a key battery material, instead of removing it as traditionally done, dramatically boosts performance. The “wet” version stores nearly twice as much charge, charges faster, and remains stable for hundreds of cycles, placing it among the top-performing sodium battery materials ever reported.
"In research published in the Journal of Materials Chemistry A, scientists examined sodium vanadium oxide, a well-known sodium-based compound. They discovered that allowing the material to retain its natural water content significantly enhances how it functions inside a battery.
"The compound, called nanostructured sodium vanadate hydrate (#NVOH), delivered far stronger results when used in its hydrated form. It stored substantially more energy, charged at a faster rate, and maintained stability for more than 400 charge cycles.
"During testing, the hydrated version held nearly twice as much charge as standard sodium-ion cathode materials. This performance places it among the top cathodes reported so far for sodium-ion batteries.
"Dr. Daniel Commandeur, Research Fellow at the University of Surrey School of Chemistry and Chemical Engineering, and lead author of the paper, said: 'Our results were completely unexpected. Sodium vanadium oxide has been around for years, and people usually heat-treat it to remove the water because it's thought to cause problems. We decided to challenge that assumption, and the outcome was far better than we anticipated. The material showed much stronger performance and stability than expected and could even create exciting new possibilities for how these batteries are used in the future.'
#Seawater Operation and Electrochemical #Desalination
"The team also explored how the material performed in salt water, an especially demanding environment for battery systems. Not only did it continue operating effectively, it also removed sodium ions from the saltwater solution. At the same time, a graphite electrode extracted chloride ions in a process known as electrochemical desalination.
"Dr. Commandeur added: 'Being able to use sodium vanadate hydrate in salt water is a really exciting discovery, as it shows sodium-ion batteries could do more than just store energy -- they could also help remove salt from water. In the long term, that means we might be able to design systems that use seawater as a completely safe, free and abundant electrolyte, while also producing #FreshWater as part of the process.' "

This #startup raised $8M to store #cleanenergy under the #sea
#SizableEnergy is reimagining pumped #hydro storage for the sea. Instead of using freshwater and #dams, company’s system uses saturated sea-salt brine – about 20% denser than #seawater – that moves between a floating reservoir and a deep-water reservoir. By harnessing gravity and #ocean depth, it can store and release gigawatt-scale power without the land use or environmental impact of onshore hydro projects.

#OceanAcidification has crossed a crucial threshold for planetary health, scientists say.
Ocean acidification, called "evil twin" of #climatecrisis, is caused when #carbondioxide is absorbed by ocean, where it reacts with water molecules leading to a fall in #pH of #seawater. It damages #coral #reefs and other #ocean habitats and, in extreme cases, can dissolve the shells.

Led by Maxim Rubin-Blum, we show the role #burrows and burrowing #animals have on in cold seeps.
Burrowing doesn't just mix sediment, it opens conduits that connect #seawater rich in NOx and sulfate to a subsurface domain rich in organic matter but poor in oxidizers. Fueling biological reactions and interacting as well as, potentially, things like diagenetic calcification.

The Physics of Cold Water May Have Jump-Started Complex #Life
When #seawater gets cold, it gets viscous. This fact could explain how single-celled #ocean creatures became multicellular when the planet was frozen during “#SnowballEarth,” according to experiments.
The prevailing scientific view is that such frigid temperatures would slow rather than speed evolution. But fossil records from 720 to 635MYA show an #evolutionary spurt preceding the development of #animals.

#Solar-powered #desalination
A new system could make #brackish #groundwater drinkable at low cost in communities where #seawater and grid power are limited. The system is a variation of a previous design based on #electrodialysis, which uses an electric field to draw out salt ions as #water is pumped through a stack of ion-exchange membranes.
