This Week in Engineering

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.

Two major developments in the Chinese aerospace industry were revealed at the recent Singapore airshow. United Aircraft Group announced a tilt rotor UAV in the six-ton class, capable of carrying cargo and passengers for both civilian and military applications, and the COMAC C919 airliner received another order for 40 aircraft for Tibet Airlines, in a special high-altitude configuration. The C919 is crucial for the success of the Chinese civilian aircraft industry, competing in the most important single aisle market segment in commercial aviation, currently dominated by the Airbus A320 series and the Boeing 737.

Carbon capture technology company Spiritus used a novel adsorbent-based direct air capture technology for CO2 in a unique way: to offset the carbon footprint of Taylor Swift’s recent transpacific jet flight from Tokyo to Las Vegas for the Super Bowl.

Can it be scaled to keep the internal combustion engine relevant?

Beijing-based Betavolt New Energy Technology Company has developed an atomic energy source, miniaturized into a form factor approximately ½ inch square and less than ¼ inch thick.

The first production batteries, called BV 100, are expected to have a lifetime of 50 years, delivering 1/10 of a milliwatt of power at 3 Volts.

In a significant and unexpected move, Ford Motor Company has announced production cuts of the all-electric F150 Lightning, assembled at the Rouge Electric Vehicle Center in Michigan.

Light trucks and sport utility vehicles are the most sold, highest margin vehicles in America, and industry analysts attribute slow EV adoption in this segment to several factors.

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.

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.

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.
