Sound waves thought to be from a 2014 meteor fireball north of Papua New Guinea were almost certainly vibrations from a truck rumbling along a nearby road, new Johns Hopkins University –led research shows. The findings raise doubts that materials pulled last year from the ocean are alien materials from that meteor, as was widely reported.

“The signal changed directions over time, exactly matching a road that runs past the seismometer,” said Benjamin Fernando, a planetary seismologist at Johns Hopkins who led the research. “It’s really difficult to take a signal and confirm it is not from something. But what we can do is show that there are lots of signals like this, and show they have all the characteristics we’d expect from a truck and none of the characteristics we’d expect from a meteor.”

The team presented their findings on March 12 at the Lunar and Planetary Science Conference in Houston.

Rivian’s 2026-bound R2 goes up against the Tesla Model Y, Hyundai Ioniq 5, Ford Mustang Mach-E, and more. Let’s see how their specs compare.

Ram has revealed a full-size electric pickup truck with class-leading specs.

Tesla hopes that more EVs will have the charging inlet in a similar location as Tesla EVs: “Additionally, we encourage all vehicle manufacturers to standardize charge port locations to the rear driver side or front passenger side.” But there are no signs that other OEMs will do that, because many of them have different ideas about the charging port location.

Because of that, Tesla is working on an additional solution—an extension cable (NACS to NACS). According to the manufacturer’s FAQ page, it will be available for purchase in the future.

In September, Tesla announced it had delivered 50,000 Superchargers worldwide, bringing greater access to rapid refueling for its electric vehicle customers.

The company is showing no signs of slowing down, as January heralded the arrival of the 55,000th fast-charging point.

Gas stoves emit nanocluster aerosol that may get deep into your respiratory system, study shows. Cooking on your gas stove can emit more nano-sized particles into the air than vehicles that run on gas or diesel, possibly increasing your risk of developing asthma or other respiratory illnesses, a new Purdue University study has found.

Combustion remains a source of air pollution across the world, both indoors and outdoors. We found that cooking on your gas stove produces large amounts of small nanoparticles that get into your respiratory system and deposit efficiently, said Brandon Boor, an associate professor in Purdue’s Lyles School of Civil Engineering, who led this research.

Based on these findings, the researchers would encourage turning on a kitchen exhaust fan while cooking on a gas stove.

The 834-hp tri-motor Cybertruck Beast is also the fourth-quickest EV we’ve ever tested, tying the 1111-hp Lucid Air sedan.

The benefits of fleet electrification are well-known, but the question of feasibility is still very real in the minds of many heavy fleet managers. To help fleets understand how electric trucks can fit into their operations, Mack Trucks is offering a mobile off-grid charging system.

Mack made the announcement earlier this week at the American Trucking Associations Technology and Maintenance Council Annual Meeting, where they showed off renderings of a Mack MD Electric carrying a “renewable propane” powered generator and 120 kW charger. While somewhat clunky as a concept, it should do a reasonable enough job of pretending to be permanent infrastructure to give a fleet manager a sense of whether or not an electric solution will work for them.

“This system will allow the customer or dealer to charge trucks – whether it’s a demo unit or a multi-unit ride-and-drive event at the dealer – without having charging infrastructure readily available at their site,” says Ryan Saba, energy solutions manager for Mack Trucks. “Mack hopes that this option will help customers more easily experience the benefits of e-mobility and a more sustainable transportation option.”

Things are different when you charge your EV from a Level 3 DC fast charger, as there is no need to convert the current from AC. Data to verify how much lower losses are when DC fast-charging isn’t readily available, but they should be about 10 percent.

Our own Tom Moloughney calculated DC fast-charging losses while topping up his Tesla Model 3 a few years back from an Electrify America station and using a CHAdeMO to NACS adapter. He charged the Model 3 from a 7 percent state of charge to 57 percent, which put about 35.5 kWh back into its battery pack, and he calculated that about 3.5 kWh of that were losses. He estimated that had he charged from flat to full, total losses would have been around 7 kWh, or about 10 percent of the vehicle’s usable battery capacity at the time.

If the fast charger in question is designed to run at 800 volts and it charges an 800-volt EV, then losses should be lower, although this needs to be tested and verified before actual loss numbers are presented.
