The new data also confirms that Texas has cemented its position as the crypto capital of the United States, as miners flock there for abundant clean energy and a permissive regulatory environment.

Texas made up 8.43% of the hashrate in the U.S. as of the end of 2021, and that percentage has jumped to 28.50% as of July 27, 2023 — though Foundry notes that the data was aggregated during a period of heavy curtailment in July, so Texas’s percentage of actual hashrate is even greater than what’s reflected on their latest map. Zhang added that Texas’s growth in Foundry’s map also had to do with the fact that the firm took on more clients there in the past two years.

Given that the U.S. is currently the world leader in terms of its share of the collective hashrate of the bitcoin network, that makes Texas the bitcoin capital of the world.

Imagine a juggler tossing balls into the air. The art of juggling is a dance between motion and pause, where the ball’s speed slows as it ascends, and then quickens on the way down. This dance reveals one of the core tenets of physics: conservation laws.

Simply put, these laws tell us that certain features of our world, like energy, don’t just vanish; they transform from one form to another. In our juggling example, the energy of motion (kinetic energy) morphs into the energy of position (potential energy) and back again.

Conservation laws aren’t just limited to juggling, or even Earth for that matter. They’re universal principles, true across various fields of physics. Yet, they aren’t always straightforward.

Researchers unveil a revolutionary material, tungsten oxide hydrate, enabling dynamic windows that adapt to light and temperature, boosting energy efficiency.

Dynamic windows have long been the dream of architects and engineers, promising buildings that adapt to varying light and temperature conditions.

Now, researchers from NC State University have taken a giant leap forward in this field by unveiling a revolutionary material known as tungsten oxide hydrate. This innovation could pave the way for the next generation of dynamic windows, offering building occupants the ability to switch their windows between three distinct modes: transparency, infrared light blocking, and glare control, according to a university release.

There is a largely untapped energy source along the world’s coastlines: the difference in salinity between seawater and freshwater. A new nanodevice can harness this difference to generate power.

A team of researchers at the University of Illinois Urbana-Champaign has reported a design for a nanofluidic device capable of converting ionic flow into usable electric power in the journal Nano Energy. The team believes that their device could be used to extract power from the natural ionic flows at seawater-freshwater boundaries.

“While our design is still a concept at this stage, it is quite versatile and already shows strong potential for energy applications,” said Jean-Pierre Leburton, a U. of I. professor of electrical & computer engineering and the project lead. “It began with an academic question—’Can a nanoscale solid-state device extract energy from ionic flow?’—but our design exceeded our expectations and surprised us in many ways.”

Lithium-ion batteries could get a significant boost in energy density from disordered rock salt (DRX), a versatile battery material that can be made with almost any transition metal instead of nickel and cobalt.

DRX cathodes could provide batteries with higher energy density than conventional lithium-ion battery cathodes made of nickel and cobalt, two metals that are in critically short supply.

The result: aspern Seestadt, reclaims a brownfield area to create a development that embraces new urban ideals while retaining the classical urban structure of old Vienna.

As aspern Seestadt has evolved, it has emerged as one of Europe’s most dynamic planned communities and an incubator for smart city initiatives. Geographic information system (GIS) technology helps planners implement clean energy and low-emission strategies and aids the long-range planning and implementation to ensure that aspern Seestadt achieves a unique balance of sustainability and livability.

-Vienna’s sustainable city within a city can be a model used by developing and developed countries dealing with housing crisis.

Lithium-ion batteries (LIBs), which store energy leveraging the reversible reduction of lithium ions, power most devices and electronics on the market today. Due to their wide range of operating temperatures, long lifespan, small size, fast charging times and compatibility with existing manufacturing processes, these rechargeable batteries can greatly contribute to the electronics industry, while also supporting ongoing efforts towards carbon neutrality.

The affordable and eco-friendly recycling of used LIBs is a long sought-after goal in the energy sector, as it would improve the sustainability of these batteries. Existing methods, however, are often ineffective, expensive or harmful to the environment.

Moreover, LIBs heavily rely on materials that are becoming less abundant on Earth, such as cobalt and lithium. Approaches that enable the reliable and cost-effective extraction of these materials from spent batteries would drastically reduce the need to source these materials elsewhere, thus helping to meet the growing LIB demand.
