The company hopes to make the new cars part of the Olympic sport.

Australia-based company Airspeeder, which engineered the world’s first flying electric racing car, is now training its electric pods to be part of the Olympic sport one day.

Airspeeder is flying racing pods which it hopes could be a demonstration sport at Brisbane Olympics 2032, according to a report by ABC News published on Friday.

“It is the future, it is pod racing in the sky… it’s Star Wars,” the company’s head of media Stephen Sidlo told ABC News.

Interesting Engineering is a cutting edge, leading community designed for all lovers of engineering, technology and science.

Juan Andres Guerrero-Saade’s speciality is picking apart malicious software to see how it attacks computers.

It’s a relatively obscure cybersecurity field, which is why last month he hosted a weeklong seminar at Johns Hopkins University where he taught students the complicated practice of reverse engineering malware.

Several of the students had little to no coding background, but he was confident a new tool would make it less of a challenge: He told the students to sign up for ChatGPT.

“Programming languages are languages,” Guerrero-Saade, an adjunct lecturer at Johns Hopkins, said, referring to what the ChatGPT software does. “So it has become an amazing tool for prototyping things, for getting very quick, boilerplate code.”

YouTube and TikTok are already rife with videos of people showing how they’ve found ways to have ChatGPT perform tasks that once required a hefty dose of coding ability.

Prime Minister Benjamin Netanyahu has proposed building a network of underground highway systems across the West Bank to enable the maintenance of territorial contiguity for both Israeli settlements and Palestinian towns, The Times of Israel’s sister site, Zman Yisrael, reported Saturday.

Netanyahu is aiming for high-speed tunnels routes designed ostensibly to address the problems of traffic jams and congestion, per the vision of the billionaire Elon Musk, and his engineering firm Boring Company.

Netanyahu presented his plans during a conversation Friday with French investors in Paris at the hotel where he spent the weekend.

It is “designed to use an inherently safe and extremely robust fuel form.”

The future of deep space exploration is near. Rolls-Royce revealed a new image of a micro-reactor for space that it says is “designed to use an inherently safe and extremely robust fuel form.”

The iconic engineering firm recently tweeted the image alongside a caption. It is designing the nuclear fission system as part of an agreement it penned with the UK Space Agency in 2021.

Nuclear propulsion systems for space, which harness the energy produced during the splitting of atoms, have great potential for accelerating space travel and reducing transit times. This could be of particular importance when sending humans to Mars… More.

Lonnie Reid is nationally recognized in turbomachinery for his knowledge of internal flow in advanced aerospace propulsion systems. He has a long history of integrating the theoretical and experimental elements of fluid dynamics work to expand the database of compressor and fan design. He has not only demonstrated excellent leadership skills in several positions, including as chief of the Internal Fluid Mechanics Division, but has been influential in recruiting and mentoring the next generation of scientists and engineers.

Lonnie Reid was born on September 5, 1935, in Gastonia, North Carolina. After serving in the U.S. Army, he earned a mechanical engineering degree from Tennessee State University. He joined the NASA Lewis Research Center as a research engineer shortly after graduating in 1961 and spent the next 20 years as both a researcher and manager in the Compressor Section of the Fluid Systems Components Division.

In the early 1960s the group focused on improving the performance of high-speed turbopumps that pumped cryogenic propellants in space vehicles. The pumping of liquid hydrogen in near-boiling conditions, referred to as “cavitation,” was a particular concern. The fluids systems researchers improved pump designs and demonstrated the ability to pump hydrogen in cavitating conditions. These were key contributions to the success of the Centaur and Saturn upper-stage rockets.

Physicists using advanced muon spin spectroscopy at Paul Scherrer Institute PSI found the missing link between their recent breakthrough in a kagome metal and unconventional superconductivity. The team uncovered an unconventional superconductivity that can be tuned with pressure, giving exciting potential for engineering quantum materials.

A year ago, a group of physicists led by PSI detected evidence of an unusual collective electron behavior in a kagome metal, known as time-reversal symmetry-breaking charge order—a discovery that was published in Nature.

Although this type of behavior can hint towards the highly desirable trait of , actual evidence that the material exhibited unconventional superconductivity was lacking. Now, in a new study published in Nature Communications, the team have provided key evidence to make the link between the unusual charge order they observed and unconventional superconductivity.

An international team of researchers has developed a technique that uses liquid metal to create an elastic material that is impervious to both gases and liquids. Applications for the material include use as packaging for high-value technologies that require protection from gases, such as flexible batteries.

“This is an important step because there has long been a trade-off between elasticity and being impervious to gases,” says Michael Dickey, co-corresponding author of a paper on the work and the Camille & Henry Dreyfus Professor of Chemical and Biomolecular Engineering at North Carolina State University.

“Basically, things that were good at keeping gases out tended to be hard and stiff. And things that offered elasticity allowed gases to seep through. We’ve come up with something that offers the desired elasticity while keeping gases out.”

Scientists have found the secret behind a property of solid materials known as ferroelectrics, showing that quasiparticles moving in wave-like patterns among vibrating atoms carry enough heat to turn the material into a thermal switch when an electrical field is applied externally.

A key finding of the study is that this control of thermal conductivity is attributable to the structure of the material rather than any random collisions among atoms. Specifically, the researchers describe quasiparticles called ferrons whose polarization changes as they “wiggle” in between vibrating atoms—and it’s that ordered wiggling and polarization, receptive to the externally applied , that dictates the material’s ability to transfer the heat at a different rate.

“We figured out that this change in position of these atoms, and the change of the nature of the vibrations, must carry heat, and therefore the external field which changes this vibration must affect the thermal conductivity,” said senior author Joseph Heremans, professor of mechanical and aerospace engineering, and engineering, and physics at The Ohio State University.

For many avid outdoorspeople, summertime and camping go hand in hand. But as climate change continues to drive summer temperatures higher, outdoor recreation could become less relaxing—and cooling technologies like fans and portable air conditioners require electricity that is seldom available at the average campsite.

Seeing an unmet need, UConn researcher Al Kasani, working with Technology Commercialization Services (TCS) and the university’s Center for Clean Energy Engineering (C2E2), has developed a new off-grid technology that allows a ’s internal to cool up to 20°F below the ambient temperature.

The tent requires just one external element to function, one that is typically found in abundance around campsites: water. A single gallon of water can power the tent’s technology for up to 24 hours.
