The Tesla Semi is proving its worth in the ongoing 2023 Run on Less Electric Depot event. In less than 48 hours, one of the Tesla Semis from PepsiCo covered a distance of 1,600 miles. As per Rocky Mountain Institute’s David Mullaney, it’s the Tesla Semi’s charging performance that is making these impressive feats possible. 

When Elon Musk unveiled the Tesla Semi way back in late 2017, he made it a point to highlight that the electric Class 8 truck would be a cut above its peers. One of the slides that were shown during the event caught the eye of social media users as it stated that the Tesla Semi will feature “BAMF performance.” 

“BAMF” typically means “bad *ss mother f**ker” on the internet, which is pretty much in line with Tesla’s humor. Based on the performance of the Tesla Semis at the 2023 Run on Less Electric Depot event so far, it would appear that such a description is indeed accurate for the vehicle. 

PepsiCo is testing three Tesla Semi units in the 2023 Run on Less Electric Depot event. One of the trucks, Tesla Semi #3, was tracked to have done 794 miles during its second day of tests. The following day, the Class 8 all-electric truck traveled a total of 806 miles. Interestingly enough, Mullaney noted that during the nearly 48-hour period and 1,600-mile journey, Tesla Semi #3 was continuously on the move. 

The Tesla Semis are not exactly running the routes with no load either. As per North American Council for Freight Efficiency (NACFE) ‘s Mike Roeth, the Tesla Semi trucks are hauling heavy loads

“We’re tracking the beverage. It’s impressive, a fairly heavy haul at nearly 80,000 pounds. It goes to one location and drops off soda, but maybe picks up some waters, goes to another location to drop off water but pick up Gatorade. We don’t really know the payload, (but) NACFE has verified that these are fairly fully loaded when they leave and stay fairly loaded. They’re not out there gaming Run on Less,” Roeth said.

Mullaney noted that such performance is only made possible by the Tesla Semi’s battery. While Tesla has not shared the full specs of the vehicle’s battery, it is evident that the Semi can take high power charges for an extended period of time. 

“PepsiCo’s Tesla Semi #3 just did 1600 miles in a little less than 48 hours, with the truck pretty much continually moving outside three brief but fruitful charges (along with two range extending mini charges). It’s really that charging that unlocks this. The early morning charge on Day 3 gets 75% SOC in about an hour (from 5% to 80%). 

“That is remarkable. This isn’t just enabled by the 750 kW charger, but also the ability of the battery to take a high power charge for a long period of time. That ‘charge curve’ remaining very steep up to and beyond 80% SOC is what really unlocks the mileage we are seeing from this truck. In the old days, charging a battery like that would fry it in pretty short order,” Mullaney said.

Elon Musk admits he was ‘clearly wrong’ about Anthropic

Elon Musk posted a candid admission on his social media platform X on June 9, declaring that he had been “clearly wrong” about Anthropic. The statement marked a notable reversal from his earlier skepticism toward the AI company.

In September, Musk had written, “Winning was never in the set of possible outcomes for Anthropic,” reflecting his view at the time that the startup had lacked the foundation or even the trajectory to succeed in what is an incredibly intense race for advanced artificial intelligence.

Musk’s latest post came amid discussion of Anthropic’s reliance on external compute resources. He praised the company’s progress, stating that Anthropic is “obviously currently the leader in AI” and that “no company has released a model as good as Mythos/Fable,” with expectations of a strong follow-up in Mythos 2.

The tone shifted dramatically from dismissal to acknowledgement of superior performance.

The context of Musk’s comments added significance. Anthropic has been operating under a recent compute deal with SpaceXAI, Musk’s AI infrastructure-focused venture. The pair entered a short-term GPU lease agreement initiated in May, providing Anthropic access to critical computing power for training and deploying its frontier models.

Some observers had speculated that Musk could leverage this dependency to disadvantage a rival. Musk directly addressed the possibility, writing, “I would never cut them off in a way that hurt them badly, even as a competitor. That’s not my style.”

To support his commitment to ethical competition, Musk referenced concrete examples from his other companies. Tesla famously open-sourced its entire portfolio of electric vehicle patents in 2014. The move was designed to accelerate the global adoption of sustainable transportation technology rather than protect proprietary advantages.

Tesla also made its Supercharger network available to competing electric vehicle manufacturers, transforming what could have remained an exclusive charging ecosystem into a shared infrastructure that benefits the broader industry and reduces barriers for EV adoption.

Musk further pointed to SpaceX’s practices, noting that the company launches satellites for competing commercial systems “with no increase in price or use of unfair terms.” He extended the principle to his social platform, observing that “even my worst enemies attack me on this platform,” underscoring preference for open discourse over retaliation.

These examples have illustrated Musk’s long-standing philosophy that long-term technological progress is best served by open competition and infrastructure sharing rather than leveraging market power to stifle rivals. In the fast-evolving AI sector, where compute resources and model capabilities determine leadership, Musk’s stance suggests a willingness to compete on innovation and performance alone.

Musk’s admission arrives as SpaceXAI itself advances its own frontier models while maintaining business relationships across the ecosystem. By publicly correcting his earlier assessment and reaffirming principles of fair play, Musk highlights a model of competition that prioritizes advancement of the field over short-term tactical advantages.

Tesla analyst says Full Self-Driving is about to have its iPhone moment

Published

A Tesla analyst believes the company’s Full Self-Driving suite is close to an “inflection point,” where people will finally realize that it is more than what it appears, similar to how many view the iPhone.

Pierre Ferragu, an analyst who has covered Tesla for many years at New Street Research, says the Full Self-Driving suite is one piece of evidence supporting the view that a Tesla is more than a car. He compared it to the iPhone and noted that the high price tag seemed like a lot for a phone early on. Then people realized the iPhone was more than just something you make calls with. It made their lives simpler.

Suddenly, that price tag was justified.

Tesla offers several models under the average transaction price for a new vehicle, which was above $49,000, according to Kelley Blue Book. However, that does not take into account that many people can still not afford a $35,000 vehicle. Ferragu offers his thoughts:

“Remember when the addressable market of the iPhone was 10 million units? Then people realized how good it was, and now, nearly 250m are sold every year.

A similar evolution for Tesla is still on the table. A Tesla is not a car, the same way an iPhone was not a phone.

A model 3 at $35k + $100 per month is too expensive for most, but only as a car, the same way a $600 iPhone was too expensive for most, until most realized it was much more than a phone.

As a tool that gets you to work peacefully every morning, it is not expensive.”

This point is valid, especially considering the iPhone’s impact on the cell phone market. There are still a handful of players, but most people you know have an iPhone. The iPhone ties into Apple’s other ecosystem of products.

This is how Tesla plans to infiltrate the automotive market, and once the company offers a fully autonomous suite, or something that can allow for unsupervised self-driving, more and more people will flock to Tesla.

Ferragu believes Tesla needs two additional quarters of development before things will truly change. He didn’t elaborate on what will happen in two quarters, but he said it will give us all time to “see where this is heading.”

It is really quite interesting to see people’s reactions when they find out what a Tesla is capable of. Full Self-Driving is a great tool for taking stress out of travel; I use it daily, and it has made it really difficult to consider taking any other car on a drive of practically any length.

To me, it is really hard to believe that people will not at least seriously consider a Tesla as their next car if they experience Full Self-Driving. This is a major point for those who argue that Tesla should advertise in some way.

NASA taps SpaceX to launch the telescope that could unlock new worlds

NASA’s Roman Space Telescope heads to orbit this August aboard SpaceX’s Falcon Heavy with massive scientific ambitions.

Published

SpaceX is set to play a central role in one of NASA’s most anticipated science missions in years. The company’s Falcon Heavy rocket, currently the most powerful operational launch vehicle in the world, will carry the Nancy Grace Roman Space Telescope into orbit on August 30 from Kennedy Space Center in Florida. Roman is now in final preparations inside the Payload Hazardous Servicing Facility, where on June 26 technicians used a crane to lift the observatory into a specialized stand for fueling and pre-launch testing.

Roman is named after Nancy Grace Roman, NASA’s first chief of astronomy, whose career helped shape how the agency approaches space science.

NASA chose SpaceX Falcon Heavy because of Roman’s needs to reach a specific orbit far from Earth, well beyond where a standard Falcon 9 can deliver it. The Falcon Heavy, which first flew in 2018, has since become NASA’s go-to option for missions that need serious muscle without the cost and complexity of older launch systems.

Roman will carry a field of view at least 100 times wider than the Hubble Space Telescope, meaning it can photograph enormous swaths of the universe in a single shot rather than the narrow slices Hubble captures. That difference in scale is significant. While Hubble reshaped our understanding of the cosmos over 30 years, Roman is built to work faster and wider, surveying hundreds of millions of galaxies at once.

One of Roman’s most compelling capabilities is its potential to discover and photograph planets orbiting stars outside our solar system, and with enough precision to directly image planets that would otherwise be lost. That means scientists could study the atmosphere and surface characteristics of distant worlds rather than simply confirming they exist. Combined with Roman’s sweeping field of view, the telescope could detect thousands of exoplanets, and some of those planets may be in habitable zones where liquid water could exist. No telescope currently in operation has this level of power and capability. That capability alone could change what we know about other worlds, and perhaps finally answer the question: are we the only intelligent lifeforms in existence? 

What Roman actually finds once it reaches orbit is an open question, and that is exactly what makes this launch worth watching.
