The Boring Company shares quick glimpse at Prufrock III in new photo

Published

on

The Boring Company recently shared a new image on its official Twitter account, showing its custom-designed tunnel boring machine (TBM), Prufrock II. The image is quite interesting as it not only showed Prufrock II — it also provided a small glimpse at its successor, Prufrock III. 

The Boring Company gave credit to its employees in its tweet, noting that the TBC team did a great job advancing rapid retrieval and continuous mining activities. “Prufrock II returns home after completing another Bastrop tunnel! Great job by TBC team in advancing rapid retrieval and continuous mining. And a subtle cameo by Prufrock III,” the tunneling startup wrote. 

At least based on Prufrock III’s small cameo in the Boring Company’s photo, it appears that the third-generation custom tunneling machine might be ready for deployment soon. The eventual launch and performance of Prufrock III are extremely interesting, considering the company’s ambitious targets for the machine.

The Boring Company formally described Prufrock during its 2018 information session. At the time, the tunneling startup noted that Prufrock would be a fully Boring Company-designed TBM. Musk noted then that Prufrock would be about 10-15x faster than current tunnel boring machines in the market. This is partly due to the startup’s all-electric approach, which makes it easier to construct cleaner tunnels. 

Prufrock’s official page on the Boring Company’s website shows that the tunnel boring machine is designed for quick projects, with the TBM designed to start tunneling within 48 hours of arrival on a digging site. It also has very lofty goals in terms of performance, with its medium-term goal exceeding “1/10 of human walking speed, which is 7 miles per day.”

That’s a pretty insane target for a tunnel boring machine. After all, a Robbins open-type TBM used in the Katoomba Carrier tunnel set several world records, posting a best day of 172.4 m (565.6 ft), a best week of 702.8 m (2,305.7 ft), and a best monthly average of 1,189 m (39,000 ft) during its operations. Such a machine would be considered very slow compared to Prufrock’s target speed. 

So far, The Boring Company appears to have deployed at least one Prufrock machine to one of its commercial projects. On February 2022, the tunneling startup shared a short video of Prufrock-1 arriving at Resorts World on the Las Vegas Strip. Considering the growing scope of the Vegas Loop, The Boring Company’s Prufrock II and Prufrock III machines may very well end up helping their predecessor build out Sin City’s Loop system.

Blue Origin announces Super-Heavy New Glenn 9×4 to Rival SpaceX Starship

The announcement followed the company’s successful NG-2 launch on November 13.

Blue Origin has revealed plans to develop New Glenn 9×4, a “super heavy” rocket designed to deliver 70 metric tons to low-Earth orbit and directly compete with SpaceX’s Starship. 

The announcement followed the company’s successful NG-2 launch on November 13, which deployed NASA’s ESCAPADE (Escape and Plasma Acceleration Dynamics Explorers) Mars mission and landed the first stage.

Upgraded engines and reusability

As noted in a Universe Today report, Blue Origin will roll out upgraded BE-4 engines producing 640,000 lbf each, up from 550,000 lbf, starting with NG-3. This should boost the New Glenn rocket’s total first-stage thrust to 4.5 million pounds. Upper-stage BE-3U engines are expected to improve from 320,000 lbf to 400,000 lbf over the next few flights as well.

“These enhancements will immediately benefit customers already manifested on New Glenn to fly to destinations including low-Earth orbit, the Moon, and beyond. Additional vehicle upgrades include a reusable fairing to support increased flight rates, an updated lower-cost tank design, and a higher-performing and reusable thermal protection system to improve turnaround time,” Blue Origin noted. 

New Glenn “Super Heavy” 9×4

The super-heavy New Glenn 9×4, with nine BE-4s on the booster, four BE-3Us on the upper stage, will feature an 8.7-meter payload fairing. Blue Origin expects New Glenn 9×4 to be capable of transporting 70 metric tons to LEO, 14 tons to GSO, and 20 tons to trans-lunar injection, as noted by the company in a blog post. This is very impressive, as New Glenn 9×4’s capacity exceeds Falcon Heavy, SpaceX’s largest rocket available to consumers today. Falcon Heavy is capable of carrying up to 64 metric tons to low Earth orbit in a fully expendable configuration.

That being said, SpaceX’s Starship’s capacity is extremely impressive. As per SpaceX, Starship is designed to be capable of carrying up to 100-150 metric tonnes to orbit in its fully reusable configuration. At its expendable configuration, Starship’s capacity enters unheard-of territory, with SpaceX stating that the vehicle could transport 250 metric tonnes of cargo.

Tesla FSD approved for testing in Nacka, Sweden, though municipality note reveals aggravating detail

Nacka, Sweden, a municipality just a few miles from Stockholm, has given its approval for FSD tests.

Tesla has secured approval for FSD testing in an urban environment in Sweden. As per recent reports from the Tesla community, Nacka, Sweden, a municipality just a few miles from Stockholm, has given its approval for FSD tests. 

A look at the municipality’s note regarding FSD’s approval, however, reveals something quite aggravating. 

FSD testing approval secured

As per Tesla watcher and longtime shareholder Alexander Kristensen, Nacka is governed by the Moderate Party. The shareholder also shared the municipality’s protocol notes regarding approval for FSD’s tests. 

“It is good that Nacka can be a place for test-driving self-driving cars. This is future technology that can both facilitate mobility and make transportation cheaper and more environmentally friendly,” the note read. 

The update was received positively by the Tesla community on social media, as it suggests that the electric vehicle maker is making some legitimate headway in releasing FSD into the region. Sweden has been particularly challenging as well, so securing approval in Nacka is a notable milestone for the company’s efforts.

Aggravating details

A look at the notes from Nacka shows that FSD’s proposed tests still met some opposition from some officials. But while some critics might typically point to safety issues as their reasons for rejecting FSD, those who opposed the system in Nacka openly cited Tesla’s conflict with trade union IF Metall in their arguments. Fortunately, Nacka officials ultimately decided in Tesla’s favor as the company’s issues with the country’s unions are a completely different matter.

“The left-wing opposition (S, Nackalistan, MP and V) voted no to this, referring to the fact that the applicant company Tesla is involved in a labor market conflict and does not want to sign a collective agreement. We believe that this is not an acceptable reason for the municipality to use its authority to interfere in a labor law conflict.

“Signing a collective agreement is not an obligation, and the company has not committed any crime. The municipality should contribute to technological development and progress, not work against the future,” the note read.

Norway’s annual roundup of the best car purchases featured Tesla’s two main sellers this year, with the Model 3 and Model Y securing top positions in their respective segments. 

Despite growing competition from European and Korean brands, both models stood out for their balance of price, performance, and everyday usability. The verdict comes as electric vehicle adoption remained above 95% of new vehicle sales in the country.

Tesla Model 3 strengthens its value position

Among compact EVs, the Tesla Model 3 maintained its position as the best overall buy thanks to its strong blend of performance, efficiency, and updated features. Reviewers noted that every trim offered compelling value, especially with the all-electric sedan’s improved cabin ergonomics and the return of the turn-signal stalk, which was one of the few previous complaints among drivers. 

The Model 3’s mix of long-range capability, low operating costs, and responsive handling has continued to set the benchmark for compact EVs in Norway. While competitors from Hyundai, Volkswagen, and Peugeot have narrowed the gap, Tesla’s price-to-capability ratio has remained difficult to beat in this segment, Motor.no reported.

“The Model 3 clearly offers the best value for money in the compact class, no matter which version you choose. Now it also gets the turn signal lever back. This eliminates one of the few flaws in a driving environment that many believe is the best on the market,” the publication wrote.

Tesla Model Y claims its crown

The Tesla Model Y emerged as Norway’s top family-car purchase this year. The latest refresh introduced improvements in ride quality, styling, and interior materials, allowing the Model Y to deliver a more premium driving experience without a substantial price increase. 

Reviewers praised its spacious cabin, strong safety profile, and practical range, all of which reinforced its appeal for families needing an all-purpose electric crossover. The Model Y remains especially notable given its continued popularity in Norway even as Tesla faces declining sales in other global markets.

“The Model Y is back as the winner in the family class. The upgrade in the new year was even more extensive than expected. It is a slightly more elegant and significantly more comfortable Model Y that solidifies its position as Norway’s best car purchase in the most important class,” the Norwegian motoring publication noted.
