🧪 Two-stage eutectic freeze crystallization of Kryvbas mine waters (EFC)

💻 Modeling with PHREEQC and FREZCHEM model.

☝️ The process is divided into two stages with inter-stage separation at -20 °C:
🔹 Stage 1 (0 to -20 °C): Freezing of fresh ice (up to ~890 g per 1 kg of feed water). Selective precipitation of mirabilite (Na₂SO₄·10H₂O), which is completely separated on the filter (~4.6 g).
🔹 Stage 2 (-20.5 to -35 °C): Deep eutectic crystallization of hydrohalite (NaCl·2H₂O) after sulfate removal (~40 g of pure salt). The total yield of technical fresh water across both stages reaches ~968 g (96.8% solvent recovery).

❗ At the output, we obtain pure solid phases and a minimal residual mother brine (~1.3% by volume) for the subsequent extraction of trace elements (Br, Li, B, I).

“The present study assesses the impacts of climate change on blue and green water in the Kessie Watershed of the Ethiopian Upper Blue Nile Basin using the SWAT+ model.
[The authors] set up [a] SWAT+ model using quality-controlled and homogenized observational climate time series… and calibrated it using a multisite calibration approach. [They] selected CMIP6 climate models for future simulations and bias-correction methods through a comprehensive performance assessment... Building on these previous studies, the present research further evaluates the reliability of combining robust climate-model selection with optimal bias-correction methods to improve the reliability of hydrological simulations. [They] then used the best-performing climate models, bias-corrected using the optimal methods, to project future changes in blue and green water in the study area…
KEY FINDINGS:
• SWAT+ effectively represented hydrological processes across multiple gauging stations in the Ethiopian Upper Blue Nile Basin.
• Ensembles of CMIP6 climate models improved the reliability of hydrological simulations compared with individual climate models.
• Optimized climate-model selection reduced biases in hydrological simulations more than bias correction alone.
• Arbitrary selection of climate models can degrade hydrological simulations, even when their outputs are bias-corrected using robust methods.
• Both blue and green water are projected to increase under future climate change in the Ethiopian Upper Blue Nile Basin.
• Blue water exhibits greater seasonality and climate sensitivity than green water flow and green water storage.
The study also provides sustainable water management options for adapting to the impacts of climate change, with implications for water resource planning and management in the Upper Blue Nile Basin…”

"We don't expect any conflict with the beaver in the next 10 years," ~ Bohumil Fiser from the Czech Nature Conservation Agency

“For seven years, planners struggled to complete a $1.2 million wetland restoration project in the Brdy region of the Czech Republic. The goal was to build a dam that would improve water management and bring back valuable wetland habitat, but the project remained trapped in a maze of permits and approvals.
Then a family of eight Eurasian beavers did what engineers had planned… without permits, machinery, or a budget.
The beavers built a network of dams in almost the exact area chosen for the proposed project, naturally restoring the wetland system officials had spent years trying to create. After seeing the results, authorities decided there was little point continuing with the original human-built dam.
Although some reports suggested the beavers completed the work overnight, experts say their construction likely took several weeks. The reason it seemed sudden is that the animals quietly worked away until their finished dams became impossible to miss.
Beavers are known as “ecosystem engineers” because their behaviour can reshape entire environments. By cutting trees and blocking streams, they create ponds and wetlands that support countless species, including fish, amphibians, insects, birds, and mammals.
Their wetlands also act as natural water reservoirs, helping during droughts, reducing flood risks, filtering water, storing carbon, and keeping landscapes wetter during wildfires…
Once heavily hunted across Europe, beaver populations have been recovering thanks to conservation efforts, proving that sometimes nature can solve problems humans spend years trying to fix…"

The Risks of Artificial Intelligence and Ways to Protect Ourselves @[email protected] · 2026-05-10 · 07:29 UTC

EFU: When We Stop Merely Measuring Reality and Start Learning Its Language

There are moments when a new unit of measurement seems, at first glance, like a technical detail. Later, it turns out to be something much more important: a change in how we think. I believe EFU may be exactly that kind of shift. It is not just another number. It is a new language for describing the flows that sustain human civilization — material, energetic, ecological, and social.

The real importance of EFU is not only what it measures, but what it reveals. It invites us to stop seeing the world as a collection of isolated data points and start seeing it as a connected system of flows. Water, energy, materials, waste, agriculture, transport, and environmental pressure are not separate stories. They are chapters of the same larger story. EFU helps make that story visible.

A New Unit, Not Just a New Label

The most interesting thing about EFU is not the number itself, but the way of thinking it encourages. When we begin to look at a problem through EFU, we no longer see only statistics. We see relationships. We see dependencies. We see thresholds, bottlenecks, imbalances, and patterns of stress that are otherwise easy to miss.

That is why EFU matters. It does not merely describe the present. It helps us ask whether a system is stable, whether it is being overburdened, and whether it can remain viable over time. In that sense, EFU is not only a measuring tool. It is a tool for understanding resilience.

Why This Could Matter More Than It First Appears

Every major historical era has had its own dominant way of measuring reality. The industrial age centered on mass, energy, and power. The digital age elevated information, data, and connectivity. The next era may well revolve around flows, pressures, limits, and ecological coherence.

EFU fits naturally into that future. It suggests that the question is not merely “how much is there?” but also:

How does it move?
What system is it part of?
What does it cost?
How long can it continue?

That is a much deeper way of thinking. It is not just accounting. It is civilizational self-awareness.

The Future Vision: When Measurement Becomes Thoughtful

What makes EFU especially exciting is that it points beyond itself. If some of the most advanced ideas in modern physics suggest that spacetime, locality, and even causality may not be fundamental, but rather emergent from a deeper layer of reality, then we are already living in a world where our old intuitions may not be enough.

EFU belongs to that broader intellectual horizon. It does not need to claim that it is “new physics.” But it can certainly be understood as a step toward a new kind of structured thinking: a way of measuring reality that is more aligned with systems, thresholds, and hidden dependencies.

In that future, artificial intelligence could become a particularly powerful partner. Not because it merely computes faster, but because it may detect patterns that are too complex for human intuition alone. If EFU is paired with AI-driven symbolic reasoning, we may not just analyze data more efficiently — we may discover new kinds of relationships:

hidden ratios,
tipping points,
structural imbalances,
and system-level laws that are difficult to express in ordinary terms.

The Intuitive Advantage

One of the strongest qualities of EFU may be its intuitive power. A good unit of measurement does not oversimplify reality. It organizes it. It makes complexity legible without distorting it.

That is especially valuable in areas like:

water management,
agriculture,
energy systems,
waste treatment,
urban planning,
and environmental policy.

In these fields, raw numbers often fail to communicate what is really happening. EFU can help bridge that gap. It can create a shared framework in which experts, decision-makers, and ordinary citizens can discuss the same problem in the same conceptual language.

That is a rare and valuable thing. A unit that improves understanding is more than a unit. It becomes a bridge.

A Small Concept With a Large Horizon

EFU may still be an emerging idea. It may need refinement, testing, and better formalization. That is not a weakness. In fact, it is often the mark of a genuinely important idea. The most transformative concepts rarely arrive in finished form. They begin as a direction, a hunch, an intuition that something essential is missing.

And perhaps that is what EFU is really pointing to: a civilization that no longer measures only what it extracts, consumes, or produces, but also what it sustains, balances, and preserves.

If that is true, then EFU is not a side project. It is a possible step toward a new intellectual culture — one that understands that the future will not be shaped only by growth, but by balance.
