Heavy-duty BEVs like the Tesla Semi won’t work—biofuels a better option: Bill Gates
Bill Gates’ recent post about electric vehicles contained a number of interesting insights about his views on electrification. While the Microsoft co-founder noted that EVs present an ideal solution for short-haul travel, he argued that battery-electric vehicles will probably never be a practical solution for heavy-duty machinery like 18-wheelers. This makes vehicles like the Tesla Semi inherently flawed, at least according to the tech visionary.
Gates explained in his post that EVs do not work as long-haul vehicles like semitrailers because batteries are big and heavy. According to Gates, this results in an inherent problem, since moving more weight would require batteries, and more batteries would result in additional weight. Thus, even if electricity is drawn from zero-carbon sources, and even with innovations in battery tech, there are simply things that batteries would not be best at.
“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.
With this in mind, the tech visionary explained that cheap alternative fuels would be a much better option than all-electric vehicles for long-haul travel. Gates noted that there are several types of these alternative fuels, though he took a particular focus on biofuels and electrofuels. The Microsoft co-founder explained that biofuels today are far different than the biofuels of the past such as ethanol. He added that some biofuels could be drawn from plants that aren’t grown for food, and some could even be used in existing engines without requiring any modifications. However, challenges remain with the rollout of biofuels for long-haul travel.
“I’m optimistic about these biofuels, but it’s too soon to think about replacing gasoline and other fossil fuels with them. Research on advanced biofuels is still underfunded, and they aren’t ready to be deployed at the scale we need. We need a lot more innovation before they become a realistic, cost-effective option for long-haul transportation,” the Microsoft co-founder wrote.
Gates also discussed electrofuels, which combine the hydrogen molecules in water with the carbon in carbon dioxide to create a liquid fuel that could work in existing internal combustion engines. According to the tech visionary, electrofuels have a lot of potential, but they remain very expensive, costing about 3 to 7 times the price of fossil fuels. The billionaire also noted that for electrofuels to work, the electricity used to create them would need to come from zero-carbon sources.
Interestingly enough, Gates’ recent post on electric vehicles did not mention Tesla at all, nor any of the company’s projects. That being said, the tech visionary’s remarks do suggest that he does not believe that the Tesla Semi could be a viable alternative to fossil fuel trucks. Gates’ stance would likely be put to the test soon enough, however, since Tesla CEO Elon Musk has stated that it is now time for the Semi’s volume production to start. This suggests that Tesla has finalized the design and specs of the Semi, whose production version will likely meet or even exceed its impressive specs, which were announced over two years ago.

Elon Musk’s Boring Company signs deal to begin Dubai Loop project
The project marks the Boring Company’s first tunneling project outside the United States.
Elon Musk’s Boring Company has signed a definitive agreement with Dubai’s Roads and Transport Authority to begin implementing the Dubai Loop.
The project marks the Boring Company’s first tunneling project outside the United States.
The Boring Company signs Dubai Loop agreement
The Boring Company signed a partnership agreement with Dubai Roads and Transport Authority on the sidelines of the World Governments Summit 2026 to start the implementation of the Dubai Loop, as per the tunneling startup in a blog post.
The agreement was signed on behalf of Dubai RTA by Mattar Al Tayer, director general and chairman of the Board of Executive Directors, and on behalf of The Boring Company by James Fitzgerald, the startup’s global vice president of business development. Senior officials from both organizations were present at the signing ceremony.
The Dubai Loop project is intended to improve passenger mobility in high-density urban areas through underground vehicle tunnels designed for faster construction and lower surface disruption than conventional transport systems.
Pilot route and project scope outlined
The first phase of the Dubai Loop will consist of a 4-mile (6.4 km) pilot route with four stations linking the Dubai International Financial Centre and Dubai Mall. The pilot phase is expected to pave the way for a full network extending up to 14 miles (22.5 km) with 19 stations connecting the Dubai World Trade Centre, the financial district, and Business Bay.
The tunnels will have a diameter of 12 feet (3.6 meters) and will be dedicated to vehicle transport. Construction will rely on tunneling methods designed to reduce costs and minimize disruption to existing infrastructure.
The pilot phase is estimated to cost about $154 million, with delivery expected roughly one year after design work and preparatory activities are completed. The full Dubai Loop network is projected to cost approximately $545 million and would take around three years to implement.
Capacity targets and next steps
Mattar Al Tayer shared his excitement about the project, stating that the Loop system will be a qualitative addition to the city’s transportation system. “The project represents a qualitative addition to Dubai’s transport ecosystem, as it enhances integration between different mobility modes and provides flexible and efficient first- and last-mile solutions.
“Studies have demonstrated the project’s efficiency in terms of capacity and operating costs, with the pilot route expected to serve around 13,000 passengers per day, while the full route is projected to have a total capacity of approximately 30,000 passengers per day,” he said.
Steve Davis, president of The Boring Company, highlighted that the partnership aims to deliver safe and efficient tunneling solutions aligned with Dubai’s long-term mobility strategy.
“We are proud to partner with the Roads and Transport Authority, one of the world’s leading entities in adopting innovative solutions in the transport sector. Through this partnership, we look forward to delivering advanced, safe, and highly efficient tunnelling solutions that support Dubai’s vision for sustainable and future mobility,” Davis stated.
Tesla executive Sendil Palani confirmed in a post on social media platform X that Full Self-Driving, despite being the most robust driver assistance program in the United States, still isn’t garnering any interest from lagging competitors.
Tesla has said on several occasions in the past that it has had discussions with a competing carmaker to license its Full Self-Driving suite. While it never confirmed which company it was, many pointed toward Ford as the one Tesla was holding dialogue with.
At the time, Ford CEO Jim Farley and Tesla CEO Elon Musk had a very cordial relationship.
Despite Tesla’s confirmation, which occurred during both the Q2 2023 and Q1 2024 Earnings Calls, no deal was ever reached. Whichever “major OEM” Tesla had talked to did not see the benefit. Even now, Tesla has not found that dance partner, despite leading every company in the U.S. in self-driving efforts by a considerable margin.

Palani seemed to confirm that Tesla still has not found any company that is remotely interested in licensing FSD, as he said on X that “despite our best efforts to share the technology,” the company has found that it “has not been proven to be easy.”

The question came just after one Tesla fan on X asked whether Tesla would continue manufacturing vehicles.
Because Tesla continues to expand its lineup of Model Y, it has plans to build the Cybercab, and there is still an immediate need for passenger vehicles, there is no question that the company plans to continue scaling its production.
However, Palani’s response is interesting, especially considering that it was in response to the question of whether Tesla would keep building cars.
Perhaps if Tesla could license Full Self-Driving to enough companies for the right price, it could simply sell the suite to car companies that are building vehicles, eliminating the need for Tesla to build its own.
While it seems like a reach because of Tesla’s considerable fan base, which is one of the most loyal in the automotive industry, the company could eventually bail on manufacturing and gain an incredible valuation by simply unlocking self-driving for other manufacturers.
The big question regarding why Tesla can’t find another company to license FSD is simply, “Why?”
Do they think they can solve it themselves? Do they not find FSD as valuable or effective? Many of these same companies didn’t bat an eye when Tesla started developing EVs, only to find themselves years behind. This could be a continuing trend.
Tesla executive Lars Moravy appeared today in front of the U.S. Senate Commerce Committee to highlight the importance of modernizing autonomy standards by establishing a federal framework that would reward innovation and keep the country on pace with foreign rivals.
Moravy, who is Tesla’s Vice President of Vehicle Engineering, strongly advocated for Congress to enact a national framework for autonomous vehicle development and deployment, replacing the current patchwork of state-by-state rules.
These rules have slowed progress and kept companies fighting tooth-and-nail with local legislators to operate self-driving projects in controlled areas.

Moravy said the new federal framework was essential for the U.S. to “maintain its position in global technological development and grow its advanced manufacturing capabilities.
He also said in a warning to the committee that outdated regulations and approval processes would “inhibit the industry’s ability to innovate,” which could potentially lead to falling behind China.
Being part of the company leading the charge in terms of autonomous vehicle development in the U.S., Moravy highlighted Tesla’s prowess through the development of the Full Self-Driving platform. Tesla vehicles with FSD engaged average 5.1 million miles before a major collision, which outpaces that of the human driver average of roughly 699,000 miles.
Moravy also highlighted the widely cited NHTSA statistic that states that roughly 94 percent of crashes stem from human error, positioning autonomous vehicles as a path to dramatically reduce fatalities and injuries.

Skeptics sometimes point to cybersecurity concerns within self-driving vehicles, which was something that was highlighted during the Senate Commerce Committee hearing, but Moravy said, “No one has ever been able to take over control of our vehicles.”
This level of security is thanks to a core-embedded central layer, which is inaccessible from external connections. Additionally, Tesla utilizes a dual cryptographic signature from two separate individuals, keeping security high.
Moravy also dove into Tesla’s commitment to inclusive mobility by stating, “We are committed with our future products and Robotaxis to provide accessible transportation to everyone.” This has been a major point of optimism for AVs because it could help the disabled, physically incapable, the elderly, and the blind have consistent transportation.
Overall, Moravy’s testimony blended urgency about geopolitical competition, especially China, with concrete safety statistics and a vision of the advantages autonomy could bring for everyone, not only in the U.S., but around the world, as well.
