    US EV sales slow, and Apple abandons its EV ambitions

    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 are climbing, and some manufacturers such as Ford have begun offering incentives to move EVs. A fundamental reason in the reduction in electric vehicle sales incentives in America and Europe was a persistently high MSRP of electric vehicles, caused by the high cost of batteries. With high interest rates making the financing of expensive purchases even more expensive, buying with persistent inflation in other consumer goods, but optional electric vehicles worldwide may be slower than predicted. * * * Want to watch this podcast as a video?

    NASA'S X-59 May Be the Key to Supersonic Air Travel

    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 watch this podcast as a video?

    China Readies Commercial VTOL Air Taxi Services

    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 summer’s Paris Olympics is expected to feature regular eVTOL service between Paris area airports, contingent on European aviation authority certification, which is expected. If successful, this may open the floodgates to low altitude, urban air mobility in cities worldwide. * * * Want to watch this podcast as a video?

    New Tech Harnesses Energy from Ocean Waves

    *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 and pinion mechanism into rotation, driving generators. The technology has been tested in real-world conditions since 2018 and has little environmental impact on marine life. Ocean wave power resources globally are approximately 500 GW, enough to potentially supply 10% of the world’s electricity needs. * * * Want to watch this podcast as a video?

    Battery Makers Face Tough New Rules for Foreign Materials and Parts Supply

    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 regime will be a pivotal factor in the rate of EV adoption in America, and the 2024 election will greatly determine where those EV batteries will be made. * * * Want to watch this podcast as a video?

    Blended Wing Body Aircraft: The Future of Air Transport?

    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 Beach, California based JetZero. 30% improvements in performance are anticipated, and the program will be accelerated, with a projected first flight of 2027. * * * Want to watch this podcast as a video?

    In This Aerospace Market, Electric Is Really Taking Off

    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 certification process right now. Four flight training companies have ordered 340 aircraft, a production run that may nucleate the first sustained mass production of electric light aircraft in America. * * * Want to watch this podcast as a video?

    Where Will EV Lithium Come From? In the Future, North Carolina

    Critics of the transition from the internal combustion engine to electric vehicles point out that many obstacles remain to full adoption. These include high costs, unknown electrical grid capacity and, importantly, access to the critical minerals necessary to create the all-important battery packs. With car battery technology, lithium is the key metal, and like other strategic inputs, most of the world supply is a long way away from America’s auto manufacturers. That, however, may be changing, as Albemarle Corporation and Caterpillar have announced a deal to collaborate on zero emissions battery-powered mining equipment for deployment at Albemarle’s Kings Mountain North Carolina lithium mine. * * * Want to watch this podcast as a video?
