The Tesla Semi’s butterfly effect will change the face of heavy-duty freight routes
In a recent interview, Auke Hoekstra, a researcher at Eindhoven University of Technology and an electric vehicle expert, explained how battery-electric trucks like the Tesla Semi could end up dominating heavy-duty freight routes in regions like Europe. According to the EV expert, weight and range limitations that are usually associated with electric vehicles may very well be quite irrelevant when it comes to the real-world use of the electric long-haulers.
While addressing questions from Clean Energy Wire, Hoekstra explained that skeptics of vehicles like the Tesla Semi often take the hardest business case that a diesel truck is able to manage. An example of this is a multi-day trip with a team of two drivers who cover thousands of kilometers in one trip. The EV expert explained that while traditional diesels still hold an advantage against their battery-electric competition in this scenario, this edge disappears when one looks at the greater trucking market.
“My research in the Netherlands has revealed that 80% of trucks – even the really big rigs, the semis – travel 750 kilometers per day at the very most, and many cover far shorter distances. That’s because if you want to cover more kilometers, things become very expensive very quickly, because you have to pay overtime, etcetera. So, in general, you can’t make a driver do more than 750 kilometers per day. Therefore, this is the range you have to hit with about 80 percent of trucks.
“Additionally, almost all trucks return to base at the end of the day – which creates ideal conditions for charging. We still have this romantic idea that truckers are on the road for weeks on end, away from home. But this scenario has become relatively rare. Most truckers simply move stuff from Rotterdam port to Venlo, halfway to Germany’s Ruhr area, to take an example from home… Many truckers do this sort of trip a couple of times per day, and then return home. So, you can charge the vehicle overnight at a default location. This means you don’t have a chicken and egg problem – you can arrange for the infrastructure and for the truck at the same time,” the EV expert remarked.
Interestingly enough, Elon Musk has recently remarked that Tesla is looking to release the Semi with a range that falls well within Hoekstra’s numbers. While speaking at the European Battery Conference, Musk stated that he believes it is feasible to achieve 800 kilometers of range for the Semi quite easily, and he also sees a path, over time at least, for the Class 8 truck to achieve an even more impressive 1,000 kilometers per charge. Such numbers can go a long way towards shifting the market’s perception of all-electric long-haulers and their limitations. Hoekstra, for his part, noted that such a scenario has already happened before with the original Tesla Roadster.
“I do remember that in the car market, things really changed when the Roadster hit the market. That really changed the conversation. It changed the whole perception of electric vehicles. The conventional wisdom back then was that you can only use them on short distances in the city. And suddenly this car appeared, and everything was possible.
“Within the next couple of years, we’ll see the first Tesla semi-trucks on the road. This will have a similarly huge impact on the conversation about electric trucks. You can just point to it and say: “Look, it’s moving there, and it is doing 800 kilometers.” Suddenly, all those people who say ‘it cannot be done’ within truck companies will hear their boss replying: ‘Well, our competitor can do it – so you will have to do it, too.’” Hoekstra said.
What’s quite remarkable is that this is not even the most exciting part of the Semi’s butterfly effect on the trucking sector. If the Tesla Semi finds solid footing in the trucking market in the same way the Model 3 found a good niche among premium midsize sedan buyers, a “Tesla Effect” of sorts could happen on the trucking market. This could come in the form of other battery-electric trucks being developed for the long-haul market. This should, in turn, result in a massive innovation push from several truck makers, similar to what is happening now with companies like Tesla, Lucid, Rivian, and veterans like Ford and GM in the consumer EV segment.

Tesla Model 3 and Model Y can now do what only Cybertruck could
Tesla Model 3 and Model Y can power your home with Powerwall 3 during outages.
Tesla has turned its two top sellers into backup batteries for the house.
Tesla Energy announced on Tuesday that Powershare Home Backup is now available for new Model 3 and Model Y vehicles paired with a Powerwall 3, saying the car can “extend your home backup by over 2 days.” Minutes later, Tesla’s main account quoted the post with a broader pitch: “With Powerwall 3, every Tesla can now serve as your home’s backup battery.”
Until this week, the Cybertruck was the only Tesla that could send power back into a home, and that capability only began working alongside Powerwall 3 last month, after years of ambitious targets.
Tesla’s updated Powershare page says every Model 3 and Model Y ordered in the U.S. or Puerto Rico on or after October 1, 2026 can use the feature. Some, but not all, earlier cars also qualify. Owners can check on the touchscreen under Software, then Additional Vehicle Information, where a capable car shows “Powershare Support: Enabled.” As Electrek reported, bidirectional power on the two cars runs through an inverter Tesla calls PCS2 Lite, and the company has not said when that part entered production on each trim.
The home side is simpler. A house that already has a Powerwall 3 and either a Wall Connector 3 or Universal Wall Connector needs no additional equipment, and Tesla says compatibility is enabled through a software update. When the grid drops, the Powerwall and the car work together, with up to 11.52 kW of continuous power available. Tesla’s “over two days” estimate assumes a home using 30 kWh per day and a car starting at a 90 percent charge. Standard trims are rated for up to two days, while the Cybertruck adds more than three.
There are limits. Powerwall 2 and Powerwall+ support is listed as “coming soon.” Model S and Model X are not included, and Grid Support, the program that lets Cybertruck owners in Texas send power back to the grid during demand spikes for bill credits, is not available for Model 3 or Model Y.
The rollout also lines up with something Elon Musk said more than three years ago. At Tesla’s March 2023 Investor Day, Musk said, “I don’t think very many people are going to want to use bidirectional charging, unless you have a Powerwall.” Tesla has now shipped the feature for its volume cars with exactly that requirement attached.
The Powerwall pairing was the hard part on Cybertruck. Tesla told owners in December 2025 that Powershare with Powerwall had been pushed to mid 2026, and lead engineer Wes Morrill explained that two devices capable of forming a home’s grid have to negotiate which one leads during an outage, across multiple generations of hardware. With that work done for the truck, Tesla was able to extend it to the Model 3 and Model Y within a month.
Ford and GM have offered home backup from their EVs for several years, but both require a separate inverter and backup hardware. Tesla’s version leans on equipment many Powerwall 3 owners already have on the wall. Powershare for the two cars also ships as part of software update 2026.38.3, the same release that began delivering Halloween Mode on Tuesday.
Tesla is now starting to ship a “Halloween Mode” that is filled with some creepy and fun features; the company says, “This spooky update turns your Tesla into a haunted house on wheels.”
The update is just the latest in a series of updates that Tesla typically ships out in a seasonal fashion. The Spring and Summer Updates provided some fun novelty items while also packing some cool features that are actually useful for the ownership experience.
This one seems to be more fun-forward, and there are not any updates to the Full Self-Driving suite or overall operation of the vehicle. Instead, these novelty features are geared toward getting you in the mood for the Fall and Halloween.

SpaceX reveals how its 1 Million AI satellite network will work and prevent space collisions
SpaceX reveals plans for one million Starmind AI satellites and calls out operators hiding maneuvers.
SpaceX has put the largest satellite count it has ever published into writing, and it says that plan only works if every other operator in orbit starts sharing what it knows.
In a new Space Safety page highlighted Tuesday morning by Sawyer Merritt on X, SpaceX said it “plans to operate up to 100,000 Starlink satellites and up to 1 million Starmind AI satellites to meet the growing demand for broadband and supercompute.” Starlink has a little over 11,000 satellites in orbit today, so the target alone implies roughly a ninefold expansion of the broadband network.
Starmind is SpaceX’s orbital AI compute constellation. Elon Musk confirmed the Starmind name in June after an xAI trademark filing surfaced, and in August SpaceX said it was working with Nvidia on the compute payload. The FCC accepted the filing for up to one million satellites back in February.

SpaceX also released a new render of what a full Starmind constellation could look like. Alongside it, SpaceX VP Michael Nicolls explained why the satellites will not operate on their own. “We need to operate clusters of satellites in tight formation to get enough coherent compute to run AI models efficiently,” Nicolls said. “A cluster will be 10-ish satellites connected with 10 terabits or so of bandwidth between them, and interconnected to the broader constellation.”
That is the most specific detail SpaceX has given on how Starmind will be built. Instead of a million independent servers, the network would work as tightly packed groups of about 10 satellites acting as one compute unit, with Starlink’s laser links carrying results back to Earth.
There is a bright and exciting future for humanity ahead – and space is fundamental to that future.
To achieve this, space safety must be done right. We encourage every operator to not only share ephemeris data proactively the same way Starlink already does, but to also adopt the high standards of space safety that SpaceX and Starlink use every day → https://t.co/QizAkQZvEm

Packing satellites that close together, at that scale, makes collision avoidance the central problem, and most of the Space Safety page is aimed at other operators. SpaceX said Starlink encountered collision risks with about 650 unique maneuvering third party satellites in 2026, and only about half of them shared data. Over six months, Starlink recorded roughly 164,000 more collision risks where the closest approach came within four hours of an unannounced maneuver.
Some operators keep maneuver plans private over proprietary concerns, while others cannot get government permission to share them. SpaceX called those policies “counterproductive,” saying they “largely only serve to create preventable collision risk between satellites.” Starlink is also offering a free ephemeris sharing and screening platform that returns risk results within a minute, backed by its Stargaze network of 30,000 optical sensors.
The push comes as the Starmind application draws opposition from astronomers and environmental groups. In a September filing with the FCC, SpaceX said each Starmind satellite could weigh up to 4,000 kg, nearly seven times the mass of a Starlink V2 Mini. Musk has brushed off crowding concerns before, telling viewers in June that “space is enormous” and that SpaceX already knows how to run very large constellations safely.
SpaceX’s Starmind page says its Gigasat factory in Bastrop, Texas, is designed to produce AI satellites at scale, with deployment of thousands of units starting as soon as late 2027.
