Recent research has demonstrated the effectiveness of ultrathin Bi4O5Br2 nanosheets with controlled oxygen vacancies in enhancing the piezocatalytic production of hydrogen peroxide (H2O2), presenting a viable, environmentally friendly alternative to traditional methods.

Hydrogen peroxide (H₂O₂) serves as a crucial chemical raw material with extensive applications in numerous industrial and everyday contexts. However, the industrial anthraquinone method of producing H₂O₂ is fraught with significant drawbacks, including high levels of pollution and energy consumption. An alternative approach involves harnessing ubiquitous mechanical energy for piezocatalytic H₂O₂ evolution, which offers a promising strategy. Despite its potential, this method faces challenges due to its unsatisfactory energy conversion efficiency.

Bi₄O₅Br₂ is regarded as a highly attractive photocatalytic material due to its unique sandwich structure, excellent chemical stability, good visible light capture ability, and suitable band structure. Aspired by its non-centrosymmetric crystal structure, piezoelectric performance has begun to enter the vision of researchers recently. However, its potential as an efficient piezocatalyst is far from being exploited, especially since the impacts of defects on piezocatalysis and piezocatalytic H₂O₂ production over Bi₄O₅Br₂ remains scanty. Thus, mechanical energy-driven piezocatalysis provides a promising method for H₂O₂ synthesis from pure water with great attraction.

Tesla Energy secured a $375 million Megapack contract in Australia. The new Tesla Megapack contract will help build a 415 MW/1660 MWh battery Down Under, one of the largest four-hour batteries in the world.

Tesla Energy will supply Megapacks to Akaysha Energy’s Orana Battery Energy Storage System (BESS). The Orana project is located in New South Wales within Central West Orana’s Renewable Energy Zone (REZ).

We are very pleased to announce the successful closing of the debt financing of the Orana project as we move into construction on Akaysha’s first four-hour BESS to date. As the largest standalone BESS financing globally, this achievement not only secures the capital for Orana’s construction but also highlights the strong support we have received from both local and international banks, as well as from BlackRock. Their commitment to advancing the energy transition in Australia and internationally has been pivotal to reaching this milestone.

In 2023, Google and Microsoft each consumed 24 TWh of electricity, surpassing the consumption of over 100 nations, including places like Iceland, Ghana, and Tunisia, according to an analysis by Michael Thomas. While massive energy usage means a substantial environmental impact for these tech giants, it should be noted that Google and Microsoft also generate more money than many countries. Furthermore, companies like Intel, Google, and Microsoft lead renewable energy adoption within the industry.

Detailed analysis reveals that Google’s and Microsoft’s electricity consumption — 24 TWh in 2023 — equals the power consumption of Azerbaijan (a nation of 10.14 million) and is higher than that of several other countries. For instance, Iceland, Ghana, the Dominican Republic, and Tunisia each consumed 19 TWh, while Jordan consumed 20 TWh. Of course, some countries consume more power than Google and Microsoft. For example, Slovakia, a country with 5.4 million inhabitants, consumes 26 TWh.

Northrop Grumman Corporation (NYSE: NOC) has announced the design and construction of the Series Hybrid Electric Propulsion AiRcraft Demonstration (SHEPARD) vehicle. The uncrewed air system developed for DARPA recently received its official X-plane designation of XRQ-73. Built in collaboration with Scaled Composites, a Northrop Grumman subsidiary, the XRQ-73 SHEPARD is a DARPA “X-prime” program leveraging hybrid electric architecture and component technologies to quickly mature a new mission-focused aircraft design with propulsion architecture and power class for the Department of Defense.

“The idea behind a DARPA X-prime program is to take emerging technologies and burn down system-level integration risks to quickly mature a new missionized long endurance aircraft design that can be fielded quickly. The SHEPARD program is maturing a specific propulsion architecture and power class as an exemplar of potential benefits for the Department of Defense,” said Steve Komadina, SHEPARD program manager.

The DARPA team includes members from the Air Force Research Laboratory (AFRL), the Office of Naval Research (ONR), and warfighters. The prime contractor for SHEPARD is Northrop Grumman Corporation’s Aeronautics Systems sector in Redondo Beach, CA. Scaled Composites, LLC is a major supplier, along with Cornerstone Research Group, Inc., Brayton Energy, LLC, PC Krause and Associates, and EaglePicher Technologies, LLC. The XRQ-73 aircraft hybrid-electric uncrewed aircraft system (UAS) will be a Group 3 UAS weighing approximately 1,250 pounds. First flight of the XRQ-73 is expected by year-end 2024.

Raytheon, an RTX (NYSE: RTX) business, has been awarded a contract from the U.S. Army Futures Command (AFC) Futures and Concepts Center (FCC) to conduct theater level concept experimentation and mission analysis to support agile learning of the future battlefield. Under the contract, a Raytheon team will use its Rapid Campaign Analysis and Demonstration Environment, known as RCADE, to develop large-scale theater scenarios to help FCC leaders assess concepts of operations in a multi-domain conflict. Quantitative data and findings from the scenarios will help identify capabilities needed to succeed in future conflicts.

RCADE is part of Raytheon’s integrated ecosystem of modeling and simulation capabilities that are fed by real-world analytics, models, and data. It creates an experimentation environment where customers can explore battlefield scenarios, assess how different variables impact mission outcomes and quickly iterate their options with greater speed. In tandem with RCADE, the technical expertise provided by Raytheon engineers will complement the U.S. Army’s analysis enterprise. They will work together to meet the challenge of the future and solve complex evolving threats.

“RCADE helps our customers look at some of the most difficult missions and evaluate how to change the outcome for the positive. Our team of highly trained experts power this groundbreaking capability, enabling it to deliver credible, unbiased solutions,” said Colin Whelan, president of Advanced Technology at Raytheon.

A Chinese research team has achieved a significant milestone in quantum computing by successfully building a device that can simulate the movement of electrons within a solid-state material.

This research, published in the journal Nature, showcases the potential of quantum computers to surpass even the most powerful supercomputers.

Understanding electron behavior is crucial for scientific advancements, particularly in the fields of magnetism and high-temperature superconducting materials. These materials could revolutionize electricity transmission and transportation, leading to significant energy savings and technological progress.

You can now get a Starlink Mini in the US, wherever you are and even if you’re not paying for a residential subscription. SpaceX started offering select users the new Starlink dish model that’s small enough to fit in a backpack in late June. Despite its small size that makes it easy to transport and carry around, the Mini used to require an existing $150 standard service plan — you could only tack on the Mini Roam service for an additional fee of $30 a month. Now, you can get it on its own with a roaming service.

The mobile regional plan costs $150 a month and will give you access to unlimited data. It’s probably the better option if you live in an RV or travel to remote locations for extended periods of time. Meanwhile, the Mini Roam plan costs $50 a month and will give you access to 50GB of data, which is likely enough if you don’t live on the road full time. Take note that you can use Mini Roam in motion anytime, as long as you’re on land. The mobile regional plan has limited in-motion use and only works when you’re going slower than 10mph, though you can choose to add data meant for in-motion use on a per-GB basis.

Like Starlink’s other terminals, you’ll have to pay for the Mini up front. It will cost you $599 for the kit, which includes a kickstand, a pipe adapter, a power supply and a cord with a USB-C connector on one end and a barrel jack on the other. (As The Verge notes, you can plug it into a 100W USB-PD power bank if you don’t have access to other power sources.) There’s no Wi-Fi router with the kit, because it’s already integrated into the dish, giving you one less component to carry.
