Elon Musk stands by Tesla Semi and rebuts Bill Gates’ critique: ‘He has no clue’
Earlier this month, tech visionary and Microsoft co-founder Bill Gates penned a blog post outlining his stance on the next generation of transportation. And while Gates was supportive of all-electric cars, he maintained that some types of vehicles, such as heavy-duty machinery like 18-wheelers, will never really work out if they were just powered by batteries.
Instead, Gates explained that other technologies such as cheap alternative fuels would work better for tasks like long-haul travel. The Microsoft co-founder mentioned biofuels and electrofuels as superior alternatives to battery-electric heavy-duty machines, partly due to their compatibility with the trucks that are already operating today.
“The problem is that batteries are big and heavy. The more weight you’re trying to move, the more batteries you need to power the vehicle. But the more batteries you use, the more weight you add—and the more power you need. Even with big breakthroughs in battery technology, electric vehicles will probably never be a practical solution for things like 18-wheelers, cargo ships, and passenger jets. Electricity works when you need to cover short distances, but we need a different solution for heavy, long-haul vehicles,” Gates wrote.
Elon Musk, for his part, recently shared his stance on Gates’ recent statement. When asked on Twitter about his thoughts on the Microsoft co-founder’s points about batteries and long-haul trucking, the Tesla CEO offered a quick, direct rebuttal. “He has no clue,” he wrote.
Inasmuch as Musk’s statement is direct, the Tesla CEO’s rebuttal may very well prove to be a key argument for battery-electric long-haul trucks. Tesla, after all, has been obsessively improving its battery tech over the years, and the results of all this work are expected to be discussed in the upcoming Battery Day event. The event, which will be held this September 22, 2020, is expected to feature a thorough discussion about Tesla’s next-generation battery cells, which would likely be pivotal to the release of even more impressive, breakthrough vehicles and energy products.
Tesla’s next vehicles like the Plaid Model S, Model X, Semi, and Cybertruck, for example, are all speculated to be fitted with the company’s next-generation cells. And Tesla being the way it is, there is a very good chance that the electric car maker will not stop with the technology it will unveil on Battery Day. Innovations will continue, work on more advanced cells will be done, recycling will be emphasized, and batteries will get even better over time. Elon Musk, for his part, has stated that 400 Wh/kg batteries with high cycle life and ready for mass production are potentially just 3 to 4 years away, and based on his previous statements, 400 Wh/kg is the point where all-electric flights could be made possible.
Ultimately, Musk and Gates’ opposing views on electric long-haulers like the Tesla Semi would likely be decided by the performance of the vehicle itself when it gets released. Fortunately, it appears that the market does not need to wait very long, seeing as Elon Musk has noted that the Semi is already poised to enter volume production. If the Semi gets embraced by long-haul companies due to its affordable operating cost, performance, and tech, and if its capabilities prove better than those announced in its unveiling, the vehicle could end up being a Class 8 humbling device for the Microsoft co-founder.
SpaceX has announced a new target date for the thirteenth test flight of Starship: Monday, July 20, with the launch window opening at 6:45 p.m ET/5:45 p.m. CT.
This is the first rescheduling attempt of Starship’s 13th test flight. It was set to launch last night, but SpaceX scrubbed the launch attempt.

CEO Elon Musk revealed that some of the engines on Starship did not start, which automatically triggers a launch abort. Two of the Raptor engines will be removed and replaced.
To be confident of a good flight, 2 Raptors will be removed & replaced. Most probable launch timing is early next week.

SpaceX officially announced the new launch window this morning.
Starship’s 13th test launch comes with a few new objectives, but SpaceX does not plan to attempt a catch of the booster, which it has done several times in the past.
For Starship’s Upper Stage, there are some adjustments to ensure engine reusability that will be assessed during the ascent, and 20 operational Starlink V3 satellites are also set to make their way into space. SpaceX also plans to attempt an in-space relight of a single Raptor engine, which is a critical demonstration for future orbital deorbit, refueling, and deep space maneuvers.
Ultimately, it will splash down in the Indian Ocean.
The continuous tests help SpaceX advance the Starship program toward eventual full reusability, operational Starlink V3 deployment, and future missions, which include NASA’s Artemis program.

SpaceX Starship Flight 13 aborted at Zero and Musk just told us what broke
Four Raptor engines failed to ignite at T-zero, forcing SpaceX to scrub Starship Flight 13 Thursday.
SpaceX scrubbed the Starship Flight 13 launch attempt Thursday evening at the last possible moment, after four of the Super Heavy booster’s 33 Raptor 3 engines failed to ignite during the startup sequence. The 90-minute window had opened at 6:45 p.m. EDT from Starbase in Boca Chica, Texas, and the countdown had proceeded without issue all day, with more than 11.5 million pounds of liquid methane and liquid oxygen being fully loaded into the rocket before the automated abort triggered. SpaceX’s launch directors posted on X, “Standing down from today’s flight test attempt,” and shut down the livestream shortly after.
Musk confirmed the root cause within hours. “Some of the engines didn’t start, triggering an automatic launch abort,” he wrote on X. “To be confident of a good flight, 2 Raptors will be removed and replaced. Most probable launch timing is early next week.” SpaceX engineers began draining propellant tanks immediately and Booster 20 was rolled back to its hangar for inspection.
The timing adds a layer of significance that did not exist during any of the previous 12 Starship flights. This is the first time SpaceX has attempted to launch Starship since the company made its stock market debut in June, listing under ticker SPCX at $135 per share. Public investors are now watching every Starship outcome in real time, and a last-second abort carries more visibility than it would have six months ago.
Flight 13 was designed to be one of the most consequential tests in the program’s history. It was set to carry 20 Starlink V3 satellites, the first operational payload Starship has ever attempted to deploy. Six of those satellites carried external cameras to photograph Starship’s heat shield from the outside during flight, which would act as a self-inspection approach SpaceX has never attempted before. The mission also needed to complete a Raptor engine relight in space, a step SpaceX skipped on Flight 12 in May after losing an engine during ascent. That Flight 12 booster also flipped 90 degrees off course during its boostback burn when five engines failed to reignite.
SpaceX has not announced an official next launch date. Musk’s “early next week” window points to July 21 or 22 at the earliest, pending the engine swap and a return to the pad.
Elon Musk flew under the radar with his recent purchase of a $1 billion energy company, according to Federal Trade Commission (FTC) documents.
Transaction number 202612350 listed Tesla and SpaceX frontman Elon Musk as the acquiring party and CF APR Super Holdings LLC as the seller, with New APR Energy, LLC as the acquired entity. The deal, which closed without public announcement, came to light on May 14.
BREAKING: Elon Musk acquires Jacksonville power company APR Energy in a deal valued at more than $1,000,000,000.00.

Analysts inferred the deal’s scale from minority stakeholder disclosures, including one report of a 5 percent interest sold for approximately $50.4 million. Fortress Investment Group had purchased APR’s assets in late 2024, rebranded the operation as New APR Energy, and subsequently transferred ownership to Musk.
APR Energy specializes in rapidly deployable power infrastructure. The company maintains one of the world’s largest fleets of mobile gas and diesel turbines, with more than 1.1 gigawatts of generation capacity. Its modular units, which are often trailer-mounted, enable turnkey installations ranging from 20 MW to over 500 MW.
APR provides full engineering, procurement, construction, operation, and maintenance services for behind-the-meter power plants, serving everything from data centers, utilities, and industrial clients.
The firm has expanded aggressively to meet surging demand, recently adding turbines and deploying over 100 MW for a major AI hyperscaler. Its solutions bridge critical gaps where grid interconnections face delays of two to five years, according to Yahoo.
The acquisition means something more for Musk. As he continues to expand projects in artificial intelligence, especially xAI, his AI venture, there is a greater need to supply energy-intensive supercomputing clusters, including the Colossus project, with what they need: reliable and high-capacity power.
Ownership of APR provides immediate access to flexible generation assets that can be deployed adjacent to data centers, reducing dependence on a strained infrastructure. It also complements Tesla’s energy storage business, so Musk will be able to pull from his own entities to address the rapid scaling demands of AI training and compute.
