IEEE Spectrum‘s transportation protection drew just below half 1,000,000 guests in 2024. Readers got here to be taught the newest information about advances in electric vehicles and battery know-how, sustainable power options, transit infrastructure and logistics, and AI and rising dangers. Considered one of our extra widespread articles reported on a problem on the intersection of know-how and athletics. Learn on to see our round-up of our most generally learn transportation articles of 2024.
ZF Friedrichshafen
Engineers at ZF Friedrichshafen AG, one of many world’s main suppliers of automotive elements, found out tips on how to make a compact, powerful electric motor that has excessive energy density abut doesn’t have rare-earth everlasting magnets. The upshot: The innovation may neutralize China’s market place, which relies on the truth that 95 p.c of the worldwide provide of uncommon earths are mined there. Considerations over the problem of continuous to decarbonize transportation if China have been to determine that nobody else could have uncommon earths may evaporate if ZF’s motor goes mainstream.

A brand new rail enterprise goals to ferry passengers between Las Vegas and the suburbs of Los Angeles quicker, extra effectively, and with much less environmental impression than making these journeys by automotive. The brand new hall, which its creator says needs to be prepared in time for the 2028 Summer Olympic Games in Los Angeles, will turn into solely the third rail line in america whose trains ever attain the 200-kilometer-per-hour mark—the unofficial minimal pace at which a practice is taken into account to be high-speed rail. Within the U.S., even trains constructed for pace are slowed to a relative crawl as a result of they have to yield the correct of method to slower freight trains on shared rail infrastructure. However maybe Brightline West, the purpose-built L.A.-to-Las Vegas line might be a bellwether for extra efforts to get People off the roadways and onto railways.

Nuclear power may be suitable for the behemoths that carry the load of world commerce on their decks, and it needs to be a welcome various to the diesel gas that at the moment retains their engines working. Now that the International Maritime Organization has set a net-zero emissions objective that the delivery business should attain by 2050, diesel should be phased out. Some business gamers need to ammonia, batteries, and hydrogen, amongst different choices for powering ships. However there’s a rising refrain of voices pushing for nuclear power, a zero-emissions know-how that already plows the oceans. The advantages: Nuclear-powered ships can go years with out refueling; they don’t want large gas tanks, which opens up more room for cargo and passengers; and the reactors themselves have gotten safer and less complicated to function with every new era.

Strong-sate batteries are anticipated to carry critical efficiency enhancements as soon as they’re commercialized and finally substitute at this time’s lithium-ion batteries. However the development cycle for such innovations often features a prolonged interval throughout which progress hits a plateau, and hopes for a fast transition from lab to industrial manufacturing are dashed. A quote that sums it up got here from Bob Galyen, proprietor of Galyen Power and former chief know-how officer for the Chinese language battery large Modern Amperex Expertise Ltd. (CATL), the world’s largest battery producer. “Strong-state is a superb know-how. But it surely’s going to be identical to lithium-ion was when it comes to the size of time it should take to hit the market. And lithium-ion took a very long time to get there.”

A consortium of U.S. federal companies pooled their funds and big selection of experience to reinvent the emergency vehicle. The hybrid electrical field truck they’ve provide you with is carbon impartial. And within the aftermath of a pure catastrophe like a twister or wildfire, the automobile, known as H2Rescue, can provide electrical energy and potable water to survivors whereas performing as a temperature-controlled command middle for rescue personnel.

It’s no shocker that know-how’s attain extends to athletic competitors. Officers on the world’s premier biking occasions, fearing that racers searching for any benefit they’ll achieve over their rivals will go overboard in enhancing their our bodies or their bikes, are actually looking out for two-wheelers with cleverly concealed electric motors. The illicit tactic, known as “motor doping,” is threatening to taint the game’s legitimacy as a lot as performance-enhancing drug scandals have. On the Paris Olympics this previous summer time, officers deployed electromagnetic scanners and X-ray imaging to fight it. The cleverly hid motors could be exhausting to identify—they should generate solely about 30 watts of additional energy to illegitimately propel a rider onto the medal stand.

After weighing the professionals and cons of a number of several types of EV battery cells—lithium-ion, these with ilicon of their anodes corresponding to silicon-polyacrylonitrile (SiCPAN) and silicon nanowire (SiNW) cells, strong state cells, and lithium-sulfur cells—researchers on the Polytechnic College of Turin, in Italy, discovered that lithium-sulfur cells would doubtless have the least environmental impression if scaled as much as industrial ranges.

A trio of specialists from the Oak Ridge National Laboratory in Tennessee wrote for IEEE Spectrum aboutan interconnected web of dilemmas looming over EVs. Combating climate change calls for that humanity kick its habit to fossil fuels. Attaining that may require a close to whole shift from inner combustion motors to electrical traction motors for transportation. However as a result of practically all such motors depend on magnets that comprise uncommon earth components—90 p.c of which come from China—automakers outdoors of China are staring down the barrel of provide chain instability. What could be carried out to sidestep that vulnerability? The authors decide up there, describing huge efforts underway geared toward designing and testing superior electric-vehicle (EV) motors that don’t use uncommon earth components (or use comparatively little of them).

BYD, the Chinese language battery large and new entrant into the ranks of automakers, is making moves with a view to strike its rivals on the highest and lowest ends of the market, the place they’re most susceptible. BYD’s new electrical supercar, the $236,000 U9, boasts efficiency rivaling hypercars such because the Bugatti Rimac Nevera, although the Bugatti’s sticker value is an order of magnitude larger. BYD’s elegant, money-saving use of lithium iron phosphate battery cells makes the 947-kilowatt (1,287-horsepower) U9’s value level doable and in addition permits the corporate to promote a plug-in hybrid that undercuts the costs of stalwarts on the economic system finish of the market together with the Toyota Corolla. What’s extra, a commuter within the $11,000 Qin Plus DM-i can drive for 55 kilometers on battery energy alone earlier than the automobile switches to gasoline propulsion.

On this business evaluation piece, Azeem Azhar, founding father of the analysis group Exponential View, pulls no punches. He says “I’ve lengthy argued that self-driving cars are metaphorically miles away from being a actuality. For years, I’ve tried to supply a tonic to the rah-rah hype that carmakers have been foisting upon us via advertising and marketing. He remembers having written, in an article printed in MIT Expertise Assessment, that, “KITT, the automotive from [the TV show] Knight Rider, will stay the gold customary for autonomous vehicles. Autonomous automobile pilots will turn into more and more bold, however the real-world hurdles will nonetheless take time to navigate, even with pleasant metropolis regulators. None will ship to the general public in 2018.”
However the pessimist has been transformed. Azhar now says, “That was then, and that is now…I’m altering my thoughts about self-driving automobiles. Removed from being a “pointless distraction,” they’re practically prepared for prime time. And robotaxis are main the cost.” And he proceeds to again up this new assertion with strong statistical evaluation.
