World’s first industrial electric excavator has a 300 kWh battery pack that triples Tesla’s P100D
Pon Equipment based in Gjelleråsen, Norway has converted an industrial diesel-powered excavator to operate on batteries alone, the first of its kind. According to the company’s CEO, Erik Sollerud, the machine uses a 300 kWh battery pack that’s three times the capacity of Tesla’s 100 kWh battery that’s found in its flagship Model S and Model X vehicle. After an eight month development process, the first of eight excavators is ready for delivery to Norway’s largest construction company, Veidekke. As a company motivated by the impact of emissions on the environment, Pon Equipment is helping pave the way for an era of emissions-free construction equipment around the world.
The base model used for the electric conversion is the Cat® 323 Hydraulic Excavator, a 28-ton machine built by American construction and mining equipment manufacturer Caterpillar. As perhaps can be expected, swapping the original 1 ton C7.1 ACERT industrial engine for 3.4 tons of batteries came with several challenges. The team at Pan first had to find batteries that could withstand the rigors of construction work, ultimately opting for the types used in boats and submarines. The torque was also problematic and had to be scaled back to behave more like a diesel. In an electric car, high torque gives rapid acceleration, but in an excavator, it will wear out the hydraulics and other systems from the stress.
A full charge on the Caterpillar 323F Z-line (zero emission) – Pan’s revised name for the modified machine – will keep it running for 5-7 hours. For reference, a 63 amp charger will give one hour of work per one hour of charging, and another option available is to keep the machine connected to power during the entirety of operation, all details provided by Sollerud as reported by Ole Henrik Johansen of Norwegian tech website Tek.no. The machine includes a built-in 400V charger.

Also, a feature of the excavator’s electric power source is the noise or rather lack of it. During operation, only a low hum and hydraulic pump actions are heard from the 323F Z-line itself, and a swapped out fuel gauge for a battery monitor is the only obvious difference inside the machine’s cabin. While the carbon emissions are negated with the removal of the diesel engine, it appears a reduction in noise pollution is a happy bonus. Each machine is estimated to cost about $650,000.
Caterpillar was supportive of Pon’s modification project, working with the company throughout the process – the industrial equipment manufacturer reportedly has an interest in developing a line of electrically powered machines. Pon has also made it clear that their goal was never to replace the Cat® 323, just create a carbon-neutral option. In a press conference on Monday, Sollerud explained, “We do not want to invent a new excavator. Cat® 323F is one of the world’s best excavators. We only want it in an emissions-free version, with the same performance as the diesel-powered.” Until Caterpillar and companies like it finalize and release its battery-powered fleet into the market, Pon Equipment will hold the title of the first and only producer of clean energy construction excavators.

The Boring Company clears final Nashville hurdle: Music City loop is full speed ahead
The Boring Company has cleared its final Nashville hurdles, putting the Music City Loop on track for 2026.
The Boring Company has cleared one of its most significant regulatory milestones yet, securing a key easement from the Music City Center in Nashville just days ago, the latest in a series of approvals that have pushed the Music City Loop project firmly into construction reality.
On March 24, 2026, the Convention Center Authority voted to grant The Boring Company access to an easement along the west side of the Music City Center property, allowing tunneling beneath the privately owned venue. The move follows a unanimous 7-0 vote by the Metro Nashville Airport Authority on February 18, and a joint state and federal approval from the Tennessee Department of Transportation and the Federal Highway Administration on February 25. Together, these green lights have cleared the path for a roughly 10-mile underground tunnel connecting downtown Nashville to Nashville International Airport, with potential extensions into midtown along West End Avenue.
Music City Loop could highlight The Boring Company’s real disruption
Nashville was selected by The Boring Company largely because of its rapid population growth and the strain that growth has placed on surface infrastructure. Traffic has become a persistent problem for residents, convention visitors, and airport travelers alike. The Music City Loop promises an approximately 8-minute underground transit time between downtown and the Nashville International Airport (BNA), removing thousands of vehicles from surface roads daily while operating as a fully electric, zero-emissions system at no cost to taxpayers.
The project fits squarely within a broader vision Musk has championed for years. In responding to a breakdown of the Loop’s construction costs, Musk posted on X: “Tunnels are so underrated.” The comment reflected a longstanding belief that underground transit represents one of the most cost-effective and scalable infrastructure solutions available. The Boring Company has claimed it can build 13 miles of twin tunnels in Nashville for between $240 million and $300 million total, a fraction of what comparable projects cost elsewhere in the country.

The Las Vegas Loop, The Boring Company’s first operational system, has served as a proof of concept. During the CONEXPO trade show in March 2026, the Vegas Loop transported approximately 82,000 passengers over five days at the Las Vegas Convention Center, demonstrating the system’s capacity during large-scale events. Nashville draws millions of convention visitors and tourists each year, and local business leaders have pointed to that same capacity as a major draw for supporting the project.
The Music City Loop was first announced in July 2025. Construction began within hours of the February 25 state approval, with The Boring Company’s Prufrock tunneling machine already in the ground the same evening. The first operational segment is targeted for late 2026, with the full route expected to be complete by 2029. The project represents one of the largest privately funded infrastructure efforts currently underway in the United States.

Elon Musk’s $10 Trillion robot: Inside Tesla’s push to mass produce Optimus
Tesla’s surging Optimus job listings reveal a company sprinting from prototype to one million robot production.
Tesla is accelerating its push to bring the Optimus humanoid robot to high volume production, and its recent job listings tells the story as clearly as any earnings call.
With well over 100 Optimus related job openings now posted across its U.S. facilities, Tesla is signaling a critical pivot for the program, moving it from a captivating tech demo to a serious manufacturing endeavor. Roles span the full spectrum of the product lifecycle, from Robotics Software Engineers and Manufacturing Engineers to Mechanical Integration Engineers and AI Engineers focused on world modeling and video generation. One active listing for a Software Engineer on the Optimus team asks candidates to build scalable and reliable data pipelines for Optimus manufacturing lines and develop automation tools that accelerate analysis and visualization for mass manufacturing.
Tesla is racing toward a one million unit annual production target. The clearest signal yet that Tesla is treating Optimus as its primary business came on January 28, 2026, during the company’s Q4 2025 earnings call. Musk announced that Tesla is ending production of the Model S and Model X, and will repurpose those lines at its Fremont, California factory to build Optimus humanoid robots.
A production intent prototype of Optimus Version 3 is planned to be ready in early 2026, after which Tesla intends to build a one million unit production line with a targeted production start by the end of 2026. To support that ramp, Tesla broke ground on a massive new Optimus manufacturing facility at Gigafactory Texas in late 2025, with ambitions to eventually reach 10 million units per year.
Tesla Giga Texas to feature massive Optimus V4 production line
The business case for scaling this aggressively is rooted in labor economics. Musk has stated that “Optimus has the potential to be the biggest product of all time,” reasoning that if Tesla can produce capable humanoid robots at scale and reasonable cost, every task currently performed by human labor becomes a potential application. In a separate statement, Musk framed Optimus’s long term importance even more bluntly, saying it could surpass Tesla’s vehicle business in scale with the potential to generate $10 trillion in revenue.
The industries Tesla is targeting first are those most burdened by repetitive physical labor. Early applications include manufacturing assembly, material handling and quality inspection, as well as logistics tasks like loading, unloading, sorting, and transporting goods in warehouses and distribution centers. Longer term, Tesla’s vision is for Optimus to penetrate household, medical, and logistics scenarios at the scale of a smartphone rollout.

Elon Musk’s Boring Co. Tunnel Vision Challenge ends with a surprise for Louisiana, Maryland and Dallas
The Boring Company stunned three cities today, awarding New Orleans, Baltimore, and Dallas free underground Loop tunnels.
Elon Musk’s The Boring Company (TBC) announced today that it is building free underground Loop tunnels in three American cities: New Orleans, Louisiana; Baltimore, Maryland; and Dallas, Texas. The company had promised one winner when it launched the Tunnel Vision Challenge in January. After receiving 487 submissions, it selected three, committing to fund and construct all of them pending a feasibility review, entirely at its own expense. For a company that has faced years of skepticism over the gap between its promises and its delivered projects, choosing to expand its commitment rather than narrow it is a notable shift in both scale and accountability.
All three projects will now enter a rigorous, fully funded diligence phase that includes meetings with elected officials, regulators, community and business leaders, geotechnical borings, and a complete investigation of subsurface utilities and infrastructure. TBC confirmed that all costs associated with this diligence process are 100% funded by the company. If all three projects pass feasibility, all three get built. If only one clears the bar, that one gets built. The company’s willingness to fund the due diligence regardless of outcome removes one of the most common early-stage barriers that kills promising infrastructure proposals before they leave a spreadsheet.
Beyond the three winners, TBC announced it will continue working with two additional entrants it found compelling enough to pursue independently: the Hendersonville Utility Tunnel in Hendersonville, Tennessee, and the Morgan’s Wonderland Tunnel in San Antonio, Texas, which would notably serve one of the nation’s premier theme parks built specifically for guests with special needs.
The challenge also coincides with TBC’s most active construction period to date. The company recently began drilling on the Music City Loop near the Tennessee State Capitol in Nashville, and in February it broke ground on a Loop in Dubai. Musk has long argued that the fundamental problem with urban infrastructure is cost and bureaucratic inertia, not engineering. “The key to solving traffic is making going 3D either up or down,” he said in 2018, a conviction now reflected in a company structure built to absorb the financial risk that typically stalls public projects for years.

The Tunnel Vision Challenge’s most underappreciated element may be what it produced beyond three winners. Submissions came from individuals, companies, and governments across states including Alaska, Arkansas, Colorado, Kansas, Louisiana, Maryland, New York, and Texas, as well as from international entrants. Musk captured the underlying logic years ago when he said, “Traffic is driving me nuts. I’m going to build a tunnel boring machine and just start digging.” Today, three American cities are counting on exactly that.
Tunnel Vision Challenge results!
We’ve been overwhelmed with the amazing submissions…so we are announcing three winners!
The Thrilling Three are:
– NOLA Loop (New Orleans, LA)
– Ravens Loop (Baltimore, MD)
– University Hills Loop (Dallas, TX)What happens next? TBC and the… https://t.co/cY2ULftfiK
