Technology Reveals Who We Are, Not The Future

Posted by in categories: energy, military

The 1st atomic bomb was nicknamed “gadget.”

Does this say something about who we are? Or does it say something about the nature of technology and the power to do good or evil?

Today we live in a universe of ever-more-powerful gadgets and humanity has never wielded more technological power because we live in the most scientifically advanced century in the history of our civilization. The paradox, however, is that ours is also the most dangerous century not only for countless other species going extinct but also for our own existence.

Researchers develop calcium metal battery with long cycle life

Posted by in categories: energy, materials

As potential alternatives to lithium-ion batteries, rechargeable calcium (Ca) metal batteries offer advantageous features such as high energy density, cost-effectiveness, and natural elemental abundance. Its properties are also thought to help accelerate ion transport and diffusion in electrolytes and cathode materials, giving it an edge over other lithium-ion battery alternatives such as magnesium and zinc.

However, many challenges impede the development of practical Ca metal batteries. The challenges include the lack of an efficient electrolyte and the absence of cathode materials with sufficient Ca2+ storage capabilities.

Now, Tohoku University researchers have developed a prototype calcium metal rechargeable battery capable of 500 cycles of repeated charge-discharge – the benchmark for practical use.

Fractons as information storage: Not yet tangible, but close

Posted by in categories: energy, mathematics, quantum physics

Excitations in solids can also be represented mathematically as quasiparticles; for example, lattice vibrations that increase with temperature can be well described as phonons. Mathematically, also quasiparticles can be described that have never been observed in a material before. If such “theoretical” quasiparticles have interesting talents, then it is worth taking a closer look. Take fractons, for example.

Fractons are fractions of spin excitations and are not allowed to possess kinetic energy. As a consequence, they are completely stationary and immobile. This makes fractons new candidates for perfectly secure information storage. Especially since they can be moved under special conditions, namely piggyback on another quasiparticle.

“Fractons have emerged from a mathematical extension of quantum electrodynamics, in which electric fields are treated not as vectors but as tensors—completely detached from real materials,” explains Prof. Dr. Johannes Reuther, at the Freie Universität Berlin and at HZB.

Static Electrons in Flat-Band Nonequilibrium Superconductors

Posted by in categories: energy, materials

Single electrons stay stationary in superconductors with “flat-band” electronic structures, which could lead to low-energy-consumption devices made from such materials.

In 2018, researchers discovered that two layers of graphene, stacked and twisted at a specific angle, could exhibit superconductivity. Theorists have determined that the electronic structure of such a twisted material approximately resembles a “flat band,” which means that the energy of the materials’ free electrons remains constant regardless of the electrons’ momenta. This phenomenon inspired a flurry of work on systems that exhibit flat-band superconductivity. However, most of the research has focused on how such systems behave under equilibrium conditions. Now Päivi Törmä of Aalto University in Finland and her colleagues have probed the behavior of superconducting flat-band systems under nonequilibrium conditions [1]. The findings could help in the design of superconducting devices with low energy consumption.

Törmä and her colleagues considered an idealized flat-band material subjected to an applied voltage, making it a nonequilibrium system. Their predictions indicate that in this nonequilibrium system the paired and unpaired electrons follow the same behavior patterns as those in an equilibrium system: unpaired electrons form stationary quasiparticles and paired electrons flow with zero resistance. Additionally, in both types of systems the flat band helps the electrons form the bound pairs required for superconductivity.

Hyundai Motor Group, LG Energy to build $4.3 billion EV battery plant in US

Posted by in categories: energy, policy, sustainability, transportation

Biden’s energy policy is paying off big time.


SEOUL, May 26 (Reuters) — South Korea’s Hyundai Motor Group and LG Energy Solution Ltd (LGES) (373220.KS) on Friday said they will build a $4.3 billion electric vehicle (EV) battery plant in the United States amid a push to take advantage of tax credits.

Manufacturers must adhere to new U.S. sourcing requirements for EV battery components and critical minerals so that buyers of their vehicles can qualify for up to $7,500 in tax credits under the Inflation Reduction Act (IRA).

Gaia: Asia’s largest wooden building sets new sustainable standard in Singapore

Posted by in categories: business, energy, sustainability

It is fireproof and produces 2,500 fewer tonnes of CO2 in comparison to traditional buildings.

Singapore is now home to the largest wooden building in Asia. Named after the Greek goddess of Earth, Gaia is a 6-story structure inside the Nanyang Technological University (NTU) in Singapore. Students and the Nanyang Business School faculty will use the 43,500m square-meter facility.

Warren Buffett’s hand-picked successor will have big shoes to fill in someday replacing the 92-year-old investing icon: ‘He’s not going to screw this up’

Posted by in categories: business, energy

Many investors worry about the future of Berkshire Hathaway after its legendary CEO Warren Buffett is gone, but most of the conglomerate’s companies have already made the transition to reporting to the man who will eventually replace the 92-year-old.

Buffett himself and executives at Berkshire Hathaway companies like See’s Candy and Dairy Queen say they don’t have any qualms about Vice Chairman Greg Abel’s ability to lead the conglomerate. Abel already oversees all of Berkshire’s noninsurance businesses. So the main parts of the CEO job he’s not already doing are overseeing the insurance side of the company and deciding how to invest Berkshire’s nearly $131 billion in cash.

Buffett reassured investors at Saturday’s annual meeting that he believes Abel is the right man for the job and that he does know how to allocate capital following the same model Buffett uses even if he’s not making those spending decisions now. Plus, Abel did help oversee a number of large acquisitions at Berkshire’s utility unit that he led from 2008 until 2018, including the purchases of NV Energy in Nevada for $5.6 billion and Canadian power transmission firm Altalink for nearly $3 billion.
