Kyiv will lose nearly two-thirds of its deposits if the Kremlin is successful in annexing Ukrainian territory.

At least $12.4 trillion worth of Ukraine’s essential natural resources, including energy and mineral deposits, are now under Russian control.

“The Kremlin is robbing Ukraine” of its natural resources, the backbone of it’s economy, according to an analysis by SecDev posted by Washington Post on August 10.

Russia’s occupation of eastern Ukraine has given it control over some of the most mineral-rich lands in Europe.

To those that were part of the dot-com era tech scene, 2022 has a familiar energy. But now it’s all about the metaverse. And, just as they did in 1993 when the World Wide Web was launched into the public domain, many are asking themselves, “what is it, anyway?” What’s real, what’s hype and where are we headed?

The truth is, much like Internet 1.0 and all of its subsequent iterations, the metaverse is being defined as it’s being built. And contrary to what many believe, it’s more than just VR headsets and avatars. The metaverse is a place, an ecosystem, and above all else, an entirely new dimension. But to better understand this, it’s important to know how the metaverse is being developed.

Engineers at MIT have developed a new battery design using common materials – aluminum, sulfur and salt. Not only is the battery low-cost, but it’s resistant to fire and failures, and can be charged very fast, which could make it useful for powering a home or charging electric vehicles.

Lithium-ion batteries have dominated the field for the last few decades, thanks to their reliability and high energy density. However, lithium is becoming scarcer and more expensive, and the cells can be hazardous, exploding or bursting into flames if damaged or improperly used. Cheaper, safer alternatives are needed, especially as the world transitions towards renewable energy and electric vehicles.

So the MIT team set out to design a new type of battery out of readily available, inexpensive materials. After a search and some trial and error, they settled on aluminum for one electrode and sulfur for the other, topped off with an electrolyte of molten chloro-aluminate salt. Not only are all of these ingredients cheap and common, but they’re not flammable, so there’s no risk of fire or explosion.

It doesn’t involve magic but mirrors and lenses.

Energy can be trapped in the form of electric charge and heat, but until now, it has been impossible to absorb it in the form of light using traditional methods. Now a team of researchers from the Hebrew University of Jerusalem and Vienna University of Technology (TU Wien) claims to have developed the perfect setup to trap light, according to a press release published by EurekAlert.

Although this isn’t the first time scientists have come up with a way to absorb light energy, it is probably the only “light trap” method using which light energy can be absorbed even by very thin and weak mediums.

Whether in photosynthesis or in a photovoltaic system: if you want to use light efficiently, you have to absorb it as completely as possible. However, this is difficult if the absorption is to take place in a thin layer of material that normally lets a large part of the light pass through.

Increased demand for super tiny electronic sensors coming from healthcare, environmental services and the Internet of Things is prompting a search for equally tiny ways to power these sensors. A review of the state of ultracompact supercapacitors, or “micro-supercapacitors,” concludes there is still a lot of research to be done before these devices can deliver on their promise.

The review appeared in the journal Nano Research Energy.

The explosion of demand in recent years for miniaturized , such as health monitors, environmental sensors and wireless communications technologies has in turn driven demand for components for those devices that have ever smaller size and weight, with lower energy consumption, and all of this at cheaper prices.

Just 1 kilo of hydrogen fuel can do the same as around 9.9 pounds of diesel.

French-based company Alstom broke new ground in transportation. The company announced the world’s first hydrogen train, the Coradia iLint, reached Bremervörde, Lower Saxony, Germany.

This regional train only emits steam and condensed water while operating with a low noise level. With this breakthrough, it has been aimed to contribute to the greenest rail network globally, Alstom says.

Alstom contributes to the greenest rail network globally CO2-emission-free trains in service just 4 years after the start of trial operations.

Managing road intersections in crowded and dynamic environments, such as urban areas, can be highly challenging. The poor management of traffic at these can lead to road accidents, wastage of fuel, and environmental pollution.

Researchers at the University of Maryland have recently developed GAMEOPT, a that could help manage unsignalized road intersections with high traffic more efficiently. The research team with members, Nilesh Suriyarachchi, Rohan Chandra, John S. Baras and Dinesh Manocha introduced their method in a recent paper to be published in the proceedings of the 25th IEEE International Conference on Intelligent Transportation Systems (IEEE ITSC 2022). This method combines optimization techniques with ideas from game theory, a mathematical construct that represents situations in which different agents are competing with one another.

“Forty percent of all crashes, 50% of serious collisions, and 20% of fatalities occur at unsignalized intersections,” Chandra, a member of the research team, told TechXplore. “Our primary objective is to improve traffic flow and in poorly regulated or unregulated traffic intersections. To achieve this objective, we propose an algorithm that combines ideas from optimization and game theory to understand how different traffic agents cooperate and negotiate with each other at traffic intersections.”

Trains that run on hydrogen.

Re-sharing.

(CNN) — The future of environmentally friendly travel might just be here — and it’s Germany that’s leading the charge, with the first ever rail line to be entirely run on hydrogen-powered trains, starting from Wednesday.

Fourteen hydrogen trains powered by fuel cell propulsion will exclusively run on the route in Bremervörde, Lower Saxony. The 93 million euro ($92.3 million) deal has been struck by state subsidiary Landesnahverkehrsgesellschaft Niedersachsen (LVNG), the owners of the railway, and Alstom, builders of the Coradia iLint trains. The Elbe-Weser Railways and Transport Company (EVB), which will operate the trains, and gas and engineering company Linde, are also part of the project.
