Venerable diesel engine builder Cummins has introduced a fuel agnostic heavy truck engine that uses an interesting modular design to create a single internal combustion powerplant capable of operating on diesel fuel, biodiesel, and gaseous fuels such as hydrogen, biogas or natural gas. Nonetheless, the fuel infrastructure will be dominated by kerosene type liquid fuels for the foreseeable future. * * * Want to watch this podcast as a video?

Mojave, California-based Stratolaunch has announced the successful test of an air-launched, hypersonic uncrewed test vehicle, the Talon TA-1. As a private company, Stratolaunch can be contracted to gather specific data in hypersonic flight in support of customer-specific aircraft and missile programs. This proprietary data can form an important and valuable source of intellectual property for air framers and give them a competitive advantage in what will almost certainly be a crowded and...

According to Kelly Blue Book, 2023 was a record year for U.S. electric vehicle sales, with 1.2 million vehicles delivered, resulting in a 7.6% total U.S. market share, up from 5.9% in 2022. Fourth-quarter EV sales were up year-over-year by 40% — big numbers, but lower than the 49% year-over-year gain in the third quarter.  Cox automotive predicts that 2024 will see EV market share in the U.S. reach 10% of all vehicles. Growth is slowing and dealer inventories of electric vehicles in America...

NASA’s new X-59 supersonic research aircraft is poised to crack the most vexing problem of commercial faster-than-sound travel: Sonic boom. The unique shape of the aircraft manages shockwave formation and is anticipated to reduce the window-rattling noise of sonic booms to a thump no louder than the slamming of a car door. If it works, a new generation of supersonic commercial airliners may be free of current FAA restrictions over supersonic operations over populated areas. * * * Want to...

For a decade after the Wright Brothers’ 1903 flight, inventors, dreamers and entrepreneurs operating out of barns and sheds all over the world built radical prototypes to turn aviation from a dangerous hobby into a practical proposition. Today, there’s a modern equivalent of that excitement in the electric vertical takeoff and landing space. The eVTOL industry has reached an important milestone, with the first commercial certification of a battery electric VTOL aircraft in China. This...

*This is our last episode of 2023! We'll be back again the week of January 8th.* Stockholm, Sweden based Corpower Ocean has developed a standalone generation source the company calls a Wave Energy Converter, a floating generator unit tethered to a seabed anchor. The converter is essentially a floating bouy, resembling a giant sport fishing float or “bobber”, containing a novel mechanism. As the converter rises and falls relative to its seabed anchor, the vertical motion is converted by a rack...

A new set of Biden administration restrictions on foreign sourced EV raw materials and components may constrain production growth just as the need for zero emission vehicles to meet EPA requirements increases. With China controlling several key minerals, the race is on to develop alternate sources, but current tax credit regimes have MSRP restrictions, putting engineers in a classic bind: increased input costs, without the ability to pass those costs on to the consumer. The regulatory...

Blended wing body airframe design has long been known to be a high-performance solution to the traditional limits on payload, range and endurance in large aircraft. The USAF ordered flying wing bombers just after World War II, and while performance benefits were demonstrated, blended wing body designs have not been applied to large transport aircraft. This may be changing, as the USAF are leading a NASA and industry team to develop a blended wing body transport prototype to be built by Long...

Artificial intelligence algorithms are incredibly complex, needing the enormous power of supercomputers to operate. OpenAI’s ChatGPT runs on a Microsoft-built supercomputer powered by 10,000 Nvidia GPU’s. It’s expensive, and power-hungry, and the company is aiming to improve performance and reduce reliance on a single chip supplier. The result may be a new in-house semiconductor design unit at the company, or possibly an acquisition of an existing chipmaker. OpenAI has also announced that...

The electrification of aviation is a difficult challenge. The high weight of batteries, and the resulting short range and limited payload that results, have limited applications of electric drive to smaller, propeller-driven general aviation aircraft. But flight training, which typically uses smaller, short range piston powered aircraft, is ideal for electrification. Denver-based Bye Aerospace has created a purpose-built two-seat electric trainer called the eFlyer2, which is in the FAA...
