Lithium produced for Tesla’s batteries is less polluting than 31 cups of coffee: researcher
There are many criticisms of electric vehicles like Teslas, and one of them involves the notion that EVs require massive amounts of water to produce the lithium in their batteries. This idea, according to Dr. Maximilian Fichtner, who serves as the Director at the Helmholtz Institute for Electrochemical Energy Storage in Germany, is not accurate at all.
In a recent conversation with Tagesspiegel Background, the battery researcher stated that the production of electric car batteries is not as extreme as what EV critics would suggest. To produce the lithium needed for a 64 kWh battery pack, for example, Fichtner stated that about 3840 liters of water are evaporated according to usual calculation methods. This is roughly comparable to the production of 250 grams of beef, 30 cups of coffee, or half a pair of jeans, according to the researcher.
Explaining further, Fichtner stated that even before electric cars like Teslas became popular, lithium was already being used in large quantities in many industrial and chemical processes. Lithium-ion batteries are also widely used in mobile devices, which are universally accepted today. “I’m always surprised that the public never talks about lithium in laptops or mobile phones – but suddenly it’s a problem with the e-car,” the battery researcher said.
But the water consumption involved in the production of lithium for electric car batteries is just the tip of the iceberg. Fichtner estimates that a 64 kWh pack is likely in the middle of various variants of the Tesla Model 3 sedan, whose long-range versions can easily go beyond 450 km (280 miles) of range per charge. If one were to infer that an electric car battery pack can remain optimal with 2,000 full charging cycles, this could equate to a total distance of about 900,000 km. And that’s with estimates on existing battery technology.
With this in mind, it appears that Tesla’s lithium-ion batteries are actually less polluting than otherwise everyday items such as steak or the aforementioned 30 cups of coffee, since they have the potential to remain in service for a very long time. About 2,000 charging cycles, after all, would likely equate to years of average EV use.
Companies like Tesla are hard at work in improving their battery cells. This much is hinted at by Tesla executives such as CEO Elon Musk and President of Automotive Jerome Guillen, both of whom have noted that Tesla’s batteries are always evolving. Fichtner expects electric car batteries to have an average lifespan of 3,000 cycles by 2025, which would make EV batteries even more environmentally-friendly.
In his recent conversation with the publication, the researcher discussed one of the most sensitive topics surrounding battery production: cobalt. Cobalt has developed a very negative reputation due to the abhorrent conditions in cobalt mines in areas such as Congo. Fortunately, many automakers have since pledged to source the cobalt used in their EVs from areas that meet stringent standards. Tesla does this and more, with the electric car maker attempting to develop cobalt-free batteries in the near future.
For now, electric car makers are in a game of cobalt reduction, and in this sense, Tesla has a notable lead. The batteries used in Volkswagen’s well-received ID.3 hatchback, for example, contain about 12-14% cobalt. The Tesla Model 3, on the other hand, only contains about 2.9% cobalt as of 2018. Fichtner predicts that if things go well, cobalt-free batteries could enter the market as early as 2025.
Maximilian Fichtner received his Ph.D. in Chemistry/Surface Science with distinction and the Hermann Billing Award for his thesis in 1992. He currently serves as the professor for Solid State Chemistry at the Ulm University and Executive Director of the Helmholtz Institute Ulm for Electrochemical Energy Storage (HIU). He has also worked in collaboration with the German ministries of Economy and Research and Education, and has served as the Chair of the 1st International Symposium on Magnesium Batteries in 2016.

Elon Musk’s xAI wins permit for power plant supporting AI data centers
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
Mississippi regulators have approved a permit allowing Elon Musk’s artificial intelligence company xAI to construct a natural gas power plant in Southaven. The facility is expected to support the company’s expanding AI infrastructure tied to its Colossus data center operations near Memphis.
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
According to the report, regulators “voted to approve the permit” of xAI subsidiary MZX Tech LLC to construct a power plant featuring 41 natural gas-burning turbines “after careful consideration of all public comments and community concerns.”
The Mississippi Department of Environmental Quality stated that the permit followed a regulatory review process that included public comments and community input. Jaricus Whitlock, air division chief for the MDEQ, stated that the project met all applicable environmental standards.
“The proposed PSD permit in front of the board today not only meets all state and federal permitting regulations, but goes above and beyond what is required by law. MDEQ and the EPA agree that not a single person around our facilities will be exposed to unhealthy levels of air pollution,” Whitlock stated.
The planned facility will help provide electricity for xAI’s AI computing infrastructure in the Memphis region.
The Southaven project forms part of xAI’s efforts to scale computing capacity for its artificial intelligence systems.
The company currently operates two major data centers in Memphis, known as Colossus 1 and Colossus 2, which provide computing power for xAI’s Grok AI models. xAI is also planning to build another large data center in Southaven called Macrohardrr, which would be located in a warehouse previously used by GXO Logistics.
Large-scale AI training requires substantial computing power and electricity, prompting technology companies to develop dedicated energy infrastructure for their data centers.
SpaceX President Gwynne Shotwell previously stated that xAI plans to develop 1.2 gigawatts of power capacity for its Memphis-area AI supercomputer site as part of the federal government’s Ratepayer Protection Pledge. The commitment was announced during an event with United States President Donald Trump.
“As part of today’s commitment, we will take extensive additional steps to continue to reduce the costs of electricity for our neighbors. xAI will therefore commit to develop 1.2 GW of power as our supercomputer’s primary power source. That will be for every additional data center as well. We will expand what is already the largest global Megapack power installation in the world,” Shotwell said.
“The installation will provide enough backup power to power the city of Memphis, and more than sufficient energy to power the town of Southaven, Mississippi where the data center resides. We will build new substations and invest in electrical infrastructure to provide stability to the area’s grid.”

Tesla China teases Optimus robot’s human-looking next-gen hands
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
A new teaser shared by Tesla’s China team appears to show a pair of unusually human-like hands for Optimus.
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
As could be seen in the teaser image, the new version of Optimus’ hands features proportions and finger structures that look strikingly similar to those of a human hand. Their appearance suggests that they might have dexterity approaching that of a human hand.
If the image reflects a new generation of Optimus’ hands, it could indicate Tesla is continuing to refine one of the most critical components of its humanoid robot.
Hands are widely viewed as one of the most difficult engineering challenges in robotics. For Optimus to perform complex real-world work, from manufacturing tasks to household activities, its hands would need to be the best in the industry.
Elon Musk has repeatedly described Optimus as Tesla’s most important long-term product. In posts on social media platform X, Musk has stated that Optimus could eventually become the first real-world Von Neumann machine.
In theory, a Von Neumann machine is a self-replicating system capable of building copies of itself using available materials. The concept was originally proposed by mathematician John von Neumann in the mid-20th century.
“Optimus will be the first Von Neumann machine, capable of building civilization by itself on any viable planet,” Musk wrote in a post on X.
If Optimus is expected to carry out complex work autonomously in the future, high levels of dexterity will likely be essential. This makes the development of advanced robotic hands a key step towards Musk’s long-term expectations for the product.

Tesla Cybercab ramps Robotaxi public street testing as vehicle enters mass production queue
Recent sightings on public roads and growing fleet activity at Giga Texas signal Tesla’s accelerating push toward the Cybercab’s commercial launch.
Tesla Cybercab is being spotted with increasing frequency both on public roads and across the grounds of Gigafactory Texas, suggesting that the company’s road testing and validation program is ramping meaningfully ahead of mass production.
A total of 25 Cybercab units were recently observed across three separate locations at Giga Texas by drone observer Joe Tegtmeyer — with 14 metallic gold units parked in a tight formation outside the factory exit, nine more at the crash testing facility undergoing structural and safety validations, and two additional units at the west end-of-line area for final checks.
The activity on public roads is just as telling. The Cybercab was spotted testing on public roads for the first time last October, near Tesla’s Engineering Headquarters in Los Altos, California, marking a significant development in the vehicle’s progression toward commercial readiness. As expected at that early stage, a safety driver was present in the seat.
Since then, sightings have only become more frequent. Community observers on X have posted fresh footage of Cybercabs navigating public streets in Silicon Valley, with each new clip adding to a growing body of evidence that Tesla’s validation efforts are well underway. The production backdrop supports the momentum. Tesla’s production line at Giga Texas moved into a higher volume early in March, representing what observers are calling the largest single-day grouping of Cybercabs seen to date.

Tesla ramps Cybercab test manufacturing ahead of mass production
Musk has also stated that Tesla is aiming for at least 2 million Cybercab units per year across more than one factory, with a potential ceiling of 4 million annually.
With testing activity on public roads accelerating and factory output visibly increasing week over week, the coming months at Giga Texas are set to be pivotal in determining how quickly Tesla can bring the Cybercab from validation to volume.
