The Boring Company to sell LEGO-like bricks made from tunneling rock

Elon Musk recently announced the next merchandise offered by the Boring Company — life-sized interlocking bricks that could be used to construct “sculptures and buildings.”

According to Musk, the blocks, which would be coming from its tunneling projects, would be rated for California seismic loads, making them strong and durable. The bricks will also be lightweight and feature a precise surface finish, making them easy to assemble.

“New Boring Company merch coming soon. Lifesize LEGO-like interlocking bricks made from tunneling rock that you can use to create sculptures & buildings. Rated for California seismic loads, so super strong, but bored in the middle, like an aircraft wing spar, so not heavy.”

Musk added several new details about the Boring Company’s interlocking bricks in succeeding tweets, stating that the first “kit” that the company would release would be the Ancient Egypt series, comprised of the pyramids, the Sphinx, the Temple of Horus, and other notable landmarks in the country. Exhibiting his humor, Musk noted that the Boring Company bricks are guaranteed to be flamethrower-proof.

While The Boring Co.’s interlocking bricks seem like a fun, weekend project for those who love working with their hands, Musk also confirmed that the blocks could easily be used for more humanitarian purposes such as the construction of low-cost houses. This was addressed by one of his followers, @LeonsArcade, who asked Musk if the bricks could be used for this purpose.  

“Yeah, the boring bricks are interlocking with a precise surface finish, so two people could build the outer walls of a small house in a day or so,” Musk responded.

While the Boring Company’s bricks might seem like a novel item like the startup’s previous offerings — the flamethrower and the hat — the product has actually been teased by the tunneling startup for a long time, as could be seen in the company’s FAQ on its official website.

According to The Boring Co., the recycling of dirt excavated from its tunnels would be one of its key projects, seeing as the bricks could be used for both the tunnel linings themselves, or in structures such as houses. As noted by the tunneling startup, earth bricks from its tunneling projects would help the company reduce its environmental impact and tunneling costs, since concrete production accounts for 4.5% of the world’s greenhouse gas emissions.

“The Boring Company is investigating technologies that will recycle the earth into useful bricks to be used to build structures.  This is not a new concept, as buildings have been constructed from Earth for thousands of years including, according to recent evidence, the Pyramids.  These bricks can potentially be used as a portion of the tunnel lining itself, which is typically built from concrete.”

As we noted in a previous report, The Boring Company has raised $10 million from the sale of its flamethrowers (later named to Not A Flamethrower). The fiery product, which was offered for $500, was manufactured for a limited 20,000-unit run. The (Not A) Flamethrower sold very well, with 4,000 units being sold within 24 hours of its release. The tunneling startup has also made progress in its bid for the Chicago-O’Hare new transportation system, with the Boring Company being one of two finalists for the project.

SpaceX is set to launch Starship tonight, provided the weather cooperates and everything with the ship goes smoothly.

This is SpaceX’s third attempt to launch Starship for its tenth test flight, with Sunday’s and Monday’s attempts both being scrapped due to a leak and unfavorable weather conditions on the respective days.

Tesla one-ups Waymo once again with latest Robotaxi expansion in Austin

Tesla’s new Robotaxi geofence measures roughly 171 square miles of Austin’s downtown and suburbs. This is more than double the size of Waymo’s geofence, which measures 90 square miles.

Tesla’s expansion of the Robotaxi geofence on Tuesday morning was a one-up on Waymo once again, as the automaker’s service area growth helps eclipse its rival in an intense back-and-forth.

A lot of conversation has been made about Tesla’s rivalry with Waymo in terms of the capabilities of its driverless ride-sharing service in Austin, Texas.

The two companies have sparred with one another, answering each other’s expansion, and continuing to compete, all to the benefit of consumers in the region.

Tesla expanded the geofence of Robotaxi once again this morning, and it is another growth that catapults it past Waymo’s service area in Austin — this time by a considerable margin.

Tesla’s new Robotaxi geofence measures roughly 171 square miles of Austin’s downtown and suburbs. This is more than double the size of Waymo’s geofence, which measures 90 square miles.

On July 14, Tesla officially overtook Waymo in terms of service area in Austin. But just a few days later, Waymo had responded with a bold statement, expanding from 37 square miles to 90 square miles.

Sarfraz Maredia, Global Head of Autonomous Mobility & Delivery at Uber, said the move “unlock[ed] another key milestone in Austin as our operating territory with Waymo expands from 37 to 90 square miles, which means that even more riders can experience Waymo’s fully autonomous vehicles through the Uber app.”

Tesla did not respond immediately, but it took its time with validation vehicle testing in the Austin suburbs, as we reported yesterday:

Tesla looks to expand Robotaxi geofence once again with testing in new area

Today’s expansion is perhaps the biggest step Tesla has taken in its efforts to continue to grow its Robotaxi platform. This is not only because the company has significantly expanded the size of the geofence, but also because it has ventured into suburban areas and even included Gigafactory Texas in its service area.

Waymo could come up with another timely response as it did when Tesla expanded in late July. We’ll wait to see what it comes up with, as this awesome competition between the two companies is accelerating innovation.

Tesla Robotaxi geofence expansion enters Plaid Mode and includes a surprise

Now, on August 26, the Robotaxi geofence has expanded once again, and is estimated to be about 130 square miles.

Tesla has expanded its Robotaxi geofence in Austin for the third time since its launch in late June, and the company added a big surprise with this new service area.

After launching on June 22, Tesla’s driverless Robotaxi service has been expanded three times. Its initial launch was about 20 square miles in size. The first expansion occurred on July 14 and was roughly 42 miles large, more than double the initial geofence size.

The second expansion occurred on August 3 and brought the total service area to roughly 80 square miles.

Now, on August 26, the Robotaxi geofence has expanded once again, and is estimated to be about 170 square miles.

The expansion of the Robotaxi geofence seemed to show the company’s focus on getting the service to the areas East and West of downtown was an utmost priority.

We reported on the Bee Cave region of the Austin suburbs being a place where Robotaxi validation vehicles were spotted testing in recent days.

Bee Cave is included in the new geofence.

However, that is not the biggest addition to the geofence, and it’s not even close. Tesla added a major area to the new geofence, one that fans of the company will absolutely love: Tesla Gigafactory Texas.

The big question that remains is whether Tesla is expanding the size of its fleet of Robotaxi vehicles in Austin. There have been many questions about the expansions of the fleet and not necessarily the geofence, and while the latter is certainly considered progress, Tesla will need to enable more Robotaxi into the vehicle population to handle the additional rides.

Tesla has been planning to do so, but is still prioritizing safety and does not want to rush any part of the Robotaxi process.

Tesla is also looking to expand to new cities altogether. It is currently moving toward a Robotaxi launch in Florida, Arizona, and Nevada, and has also opened up job postings for Robotaxi operators in New York.
