800 hp in a circle box — Dark Matter engine changes the history of EVs

Posted by in categories: cosmology, engineering, particle physics, sustainability

Meet the Dark Matter, the groundbreaking electric motor powering Koenigsegg’s new Gemera hypercar. Officially known as the Dark Matter Raxial Flux 6-phase E-motor, this revolutionary piece of technology debuted at the 2023 Goodwood Festival of Speed. Boasting an impressive 800 horsepower and 922 lb-ft of torque, while weighing just 40kg, the Dark Matter is hailed as the world’s most powerful automotive-grade electric motor. With its unique six-phase technology, it marks a major leap forward in electric vehicle engineering, surpassing the three-phase motors commonly used in most electric vehicles today.

The Dark Matter electric motor is considered the world’s most powerful automotive-grade motor, using a unique six-phase technology. This motor is a significant improvement over the three-phase motors commonly used in most electric vehicles today. The Dark Matter replaces the previous motor used in the Gemera, called the Quark.

Both the Quark and the Dark Matter are “raxial flux” motors, which combine features of two common types of electric motors: radial flux and axial flux. Radial flux motors offer more power but less torque, while axial flux motors are known for providing high torque but with less power. The key difference between these two designs is how the magnetic field travels through the motor. In a radial flux motor, the magnetic field path is longer, creating more power. In an axial flux motor, the magnetic field follows a shorter, more direct path, giving the motor more torque.

The Race to the Stars: Building the Multigenerational Interstellar Spaceship

Posted by in categories: alien life, physics, sustainability, transportation

Humanity’s fascination with the unknown is a timeless impulse, rooted in curiosity and the desire to push boundaries, uncover mysteries, and open doors to new frontiers. What were once represented by voyages and the discovery of new islands and continents are now pursued in the vastness of the Universe. As we seek answers, provoke new questions, and open doors to endless possibilities, this drive continues to inspire. It has shaped countless literary and cinematic works, transforming interstellar exploration from a science fiction concept into a vision increasingly grounded in reality. One such visionary project is Project Hyperion, spearheaded by the Initiative for Interstellar Studies (i4is), which challenges humanity to develop practical solutions for interstellar travel through a design competition. By envisioning generation ships—vast, self-sustaining habitats capable of supporting multigenerational societies on journeys spanning centuries—the project not only pushes the boundaries of technology but also sparks social innovation, stretching the limits of our collective imagination.

The exploration of outer space, which began during the Cold War space race with milestones like the launch of Sputnik in 1957 and the Apollo 11 Moon landing in 1969, has driven advances in science, technology, and geopolitics. Since then, continuous efforts such as the International Space Station (ISS), launched in 1998, have provided platforms for microgravity experiments essential to research in biomedicine and physics, as well as preparation for lunar and Martian missions. Simultaneously, spacecraft have evolved from orbital missions to interplanetary exploration and, more recently, space tourism, with vehicles like SpaceX’s Crew Dragon and Blue Origin’s New Shepard offering unique experiences in space.

However, the challenge of interstellar exploration—journeys beyond our solar system to distant stars—presents far greater complexity and requires a radical reimagining of space technology. An interstellar spacecraft would not simply be a scaled-up version of today’s spaceships but a structure capable of sustaining journeys lasting centuries, traversing immense distances. To endure such long voyages, these ships must be self-sustaining, with closed-loop life support systems, food production, and resource recycling, creating an environment where people are born, live, and die. Beyond technological challenges, there are also social and psychological hurdles to prolonged space travel. Such a ship must be not only a high-performance machine but also a viable habitat for living, working, and fostering a society across generations. This requires rethinking how we organize coexistence, social relationships, and power dynamics in an isolated and confined environment.

NASA Unveils New Approach for Mars Sample Return Program

Posted by in categories: solar power, space, sustainability

How will NASA conduct its Mars Sample Return (MSR) Program? This is what the renowned space agency recently discussed as it unveiled two potential landing options for MSR with the goal of determining a final option during the second half of 2026. This comes after NASA tasked a Mars Sample Return Strategic Review team to evaluate 11 proposals in September 2024 for returning samples from Mars to Earth while achieving cost-effectiveness while maximizing mission success.

Both options still call for loading the 30 sample tubes that have been collected and dropped across the Martian surface by NASA’s Perseverance rover during its trek on Mars. However, the Mars Ascent Vehicle, which will lift off from the Martian surface and deliver the samples to the orbiting capsule, will be smaller than previous designs. Additionally, past designs of the landed platform called for solar panels for energy, whereas new designs will incorporate a radioisotope power system for energy needs.

“Pursuing two potential paths forward will ensure that NASA is able to bring these samples back from Mars with significant cost and schedule saving compared to the previous plan,” NASA Administrator Bill Nelson said in a statement. “These samples have the potential to change the way we understand Mars, our universe, and – ultimately – ourselves. I’d like to thank the team at NASA and the strategic review team, led by Dr. Maria Zuber, for their work.”

Quantum breakthrough may lead to sustainable chiral spintronics

Posted by in categories: computing, nanotechnology, particle physics, quantum physics, sustainability

A team of physicists led by The City College of New York’s Lia Krusin-Elbaum has developed a novel technique that uses hydrogen cations (H+) to manipulate relativistic electronic bandstructures in a magnetic Weyl semimetal—a topological material where electrons mimic massless particles called Weyl fermions. These particles are distinguished by their chirality or “handedness” linked to their spin and momentum.

In the magnetic material MnSb₂Te₄, researchers unveiled a fascinating ability to “tune” and enhance the chirality of electronic transport by introducing , reshaping on-demand the energy landscapes—called Weyl nodes—within the material. This finding could open a breadth of new quantum device platforms for harnessing emergent topological states for novel chiral nano-spintronics and fault-tolerant quantum computing. Entitled “Transport chirality generated by a tunable tilt of Weyl nodes in a van der Waals topological magnet,” the study appears in the journal Nature Communications.

The tuning of Weyl nodes with H+ heals the system’s (Mn-Te) bond disorder and lowers the internode scattering. In this process—which The City College team tests in the Krusin Lab using angularly-resolved electrical transport—electrical charges move differently when the in-plane is rotated clockwise or counterclockwise, generating desirable low-dissipation currents. The reshaped Weyl states feature a doubled Curie temperature and a strong angular transport chirality synchronous with a rare field-antisymmetric longitudinal resistance—a low-field tunable ‘chiral switch’ that is rooted in the interplay of topological Berry curvature, chiral anomaly and a hydrogen-mediated form of Weyl nodes.

The far-reaching impacts of wildfire smoke — and how to protect yourself

Posted by in categories: climatology, neuroscience, sustainability

The air we breathe can have profound effects on our physical and mental health. Is there any way of protecting yourself from this pervasive problem?

All but 1% of the world’s population is exposed to unhealthy air that exceeds World Health Organization (WHO) limits for pollutants. In parts of the world, air quality has rapidly improved through policies that aim to limit pollution. But elsewhere, gains in air quality are at risk of being lost.

More than 25% of the US population is exposed to air considered “unhealthy” by the Environmental Protection Agency (EPA), according to a report by the climate non-profit First Street Foundation. By 2050, the number of people exposed to “unhealthy” days is set to increase by more than half. The worst days of air pollution (“hazardous” or maroon, under the EPA’s system) are expected to rise by 27%.
