Because distracted drivers in a 6,660lb vehicle is a great idea.

American start-up Boom Supersonic is planning to develop the very first supersonic aircraft powered by 100% sustainable fuel. The aircraft, named Overture, would succeed Concorde in providing ultrafast connections between Europe and the United States, more than 20 years after the latter ceased operation. The new aircraft also echoes its predecessor’s unique, long and slender design.

Boom Supersonic is currently flying a demonstrator, the XB-1, over the Mojave Desert in California. A first supersonic flight (at Mach 1) is now expected by the end of 2024, following the green light given from the Federal Aviation Administration (FAA). All these tests are designed to ensure the aircraft’s reliability and maneuverability. Above all, they lay the foundations for the firm’s future Overture plane.

Extinct volcanoes are hard to study – we never see them erupt. Using a unique experimental technique, we were able to recreate a certain type of extinct volcano in a lab, learning more about the magma these volcanoes produce.

We found that some rare magma types are surprisingly efficient at concentrating rare earth elements. This is a group of metals with crucial applications in several high-tech industries, such as magnets for electric vehicles and wind turbines.

Demand for rare earths is soaring as society moves away from fossil fuels and electrifies energy production and transport. Despite the name, rare earths aren’t particularly rare. The biggest challenge is finding rocks in which these metals are concentrated enough to be economically viable to extract.

While most of us are still struggling to find SSDs with greater capacities than 4TB, Samsung is working on creating the world’s first petabyte SSD. At least, that’s their plan. Last year, reports suggested that the company was about a decade away. Now, they seem much closer.

As the world’s largest manufacturer of 3D NAND storage, they’re certainly one of the most likely to do it. Samsung has revealed more information about its planes, and how it’s working to get to that 1,000-layer NAND required for such high capacities.

Samsung has long been a leader in large capacity solid state drives. And while they’re not readily available to the average consumer due to their (still) prohibitively expensive prices, Samsung announced a 16TB SSD way back in 2015.

For the most part, we treat electric aviation like it’s something that we’ll see in the future. I mean, batteries are expensive and heavy, and they don’t hold that much energy per unit of weight. So, compared to, say, kerosene (jet fuel), batteries take up a lot more space and weight capacity in a plane design. This means either really poor range or carrying around nothing but batteries (which isn’t very useful).

But that’s only true for the largest of planes. The smaller the plane, the easier it has been for companies to electrify or even go full electric with it it. Once you get down to unmanned planes and helicopters that carry something like a small sensor payload (cameras, etc.), you’re in a realm where all-electric aviation has been around for over a decade.

52 billion solar panels could soon be covering the American highway network. Researchers from the Chinese Academy of Sciences, Tsinghua University, Chinese Academy of Geosciences, and Columbia University have proposed a historic initiative which could see major global highways covered with solar panels.

The researchers publication “Roofing Highways With Solar Panels Substantially Reduces Carbon Emissions and Traffic Losses” in Earth’s Future advocate for the deployment of solar technology across the global highway network which spans up to 3.2 million kilometers.

In doing so, the researchers estimate that up to 17,578 TWh of electricity could be generated annually. This figure is equivalent to more than a staggering 60% of 2023’s energy consumption. This could offset up to 28% of global carbon emissions and reduce road accident incidences up to 11%.

As a trailblazer in clean logistics, Hyzon continues to leverage hydrogen’s potential to fuel transportation innovations.

Hyzon Motors is making significant strides in revolutionizing the heavy-duty transportation industry with the production of its pioneering Class 8 200kW Fuel Cell Electric Truck. This milestone highlights the company’s dedication to advancing zero-emission technology and addressing sectors traditionally reliant on diesel.

The vehicle production results from a strategic partnership with North Carolina-based Fontaine Modification, which assembles the trucks by integrating Hyzon’s advanced fuel cell systems, battery packs, and hydrogen storage solutions into the chassis. This collaboration ensures each vehicle meets new standards in innovation and road-readiness.

Scientists identified a new mechanism causing lithium-ion battery self-discharge and degradation: cathode hydrogenation. They revealed how protons and electrons from the electrolyte impact the cathode.

Lithium-ion (or Li-ion) batteries are heavy hitters when it comes to the world of rechargeable batteries. As electric vehicles become more common in the world, a high-energy, low-cost battery utilizing the abundance of manganese (Mn) can be a sustainable option to become commercially available and utilized in the automobile industry.

Currently, batteries used for powering electric vehicles (EVs) are nickel (Ni) and cobalt (Co)-based, which can be expensive and unsustainable for a society with a growing desire for EVs.

By switching the positive electrode materials to a lithium/manganese-based material, researchers aim to maintain the high performance of Ni/Co-based materials but with a low-cost, sustainable twist.
