The Boring Co. Chicago tunnel project under discussion with DOT officials

Published

on

The Boring Company’s plans of building a high-speed underground transit system connecting downtown Chicago and O’Hare airport has taken a step forward, with Chicago Mayor Rahm Emanuel meeting with senior Department of Transportation officials on Monday. The meeting, which lasted for an hour, was held at the DOT headquarters in Washington.

“Mayor Emanuel provided DOT officials with an update on the Chicago Loop project. Chicago reaffirmed that there will be no federal funds involved. All parties agreed to work together and stay in close communication,” a DOT spokesman confirmed with Reuters on Thursday.

The Chicago Mayor met with several senior DOT officials, including Federal Railroad Administrator Ron Batory and Undersecretary of Transportation for Policy Derek Kan. The discussions reportedly covered several topics, such as the specific type of environmental review the high-speed underground tunnels would require, which transportation agency will oversee the project, and if the department would tap a specific person to oversee the approval of the tunnels’ permits.

The Chicago-O’Hare transit system is the Boring Company’s first high-profile undertaking. According to Tesla and SpaceX CEO Elon Musk, the Chicago tunnel, which will be more than 17 miles long, would cost roughly $1 billion to construct. The entire project will be privately funded, with no subsidies from taxpayers. As noted by Elon Musk in a press conference in Chicago, the initial digging on both sides of the planned tunnel could start in as early as three to four months. Musk expects the tunnel to be operational in 18-24 months after the initial digging.

The high-speed underground transit line is an opportunity for the Boring Company to flex its creative muscles and prove to the market that it is a serious player in the transportation industry. Prior to winning the contract in Chicago, the tunneling startup has only been involved in the construction of a test tunnel under the SpaceX headquarters in Hawthorne, CA, as well as a proposed proof-of-concept tunnel that is expected to run across Culver City in CA. With the Chicago-O’Hare project, however, the tunneling startup can ultimately prove that Elon Musk’s concept of an underground transit line is feasible and effective.

Based on the details that have been released about the project thus far, the Boring Co.’s Chicago initiative is set to showcase some impressive technology. The pods that will be used for the tunnels, for example, will be designed and manufactured by Tesla, a company that Musk heads. Each pod is capable of transporting up to 16 passengers at a time at speeds of up to 150 mph, thanks to an eight-wheel design that would be fitted on the sides of the vehicle. Travel time from downtown Chicago to O’Hare airport through the Boring Company’s tunnels is estimated to take around 12 minutes, far shorter than the 30-45 minutes the trip usually takes through conventional modes of transportation.

The Boring Company might be considered as a side project or hobby of Elon Musk, but the potential of the tunneling startup is substantial. Berenberg analyst Alexander Haissl, for one, noted that if the company does finish the Chicago-O’Hare tunnel, it could raise the Boring Company’s valuation to as much as $16 billion.

Tesla teases new market entrance with confusing and cryptic message

Tesla teased its entrance into a new market with a confusing and what appeared to be cryptic message on the social media platform X.

The company has been teasing its entrance into several markets, including Africa, which would be a first, and South America, where it only operates in Chile.

In September, Tesla started creating active job postings for the Colombian market, hinting it would expand its presence in South America and launch in a new country for the first time in two years.

Tesla job postings seem to show next surprise market entry

The jobs were related to various roles, including Associate Sales Manager, Advisors in Sales and Delivery, and Service Technicians. These are all roles that would indicate Tesla is planning to launch a wide-scale effort to sell, manage, and repair vehicles in the market.

Last night, Tesla posted its latest hint, a cryptic video that seems to show the outline of Colombia, teasing its closer than ever to market entry:

This would be the next expansion into a continent where it does not have much of a presence for Tesla. Currently, there are only two Supercharger locations on the entire continent, and they’re both in Chile.

Tesla will obviously need to expand upon this crucial part of the ownership experience to enable a more confident consumer base in South America as a whole. However, it is not impossible, as many other EV charging infrastructures are available, and home charging is always a suitable option for those who have access to it.

Surprisingly, Tesla seems to be more concerned about these middle-market countries as opposed to the larger markets in South America, but that could be by design.

If Tesla were to launch in Brazil initially, it may not be able to handle the uptick in demand, and infrastructure expansion could be more difficult. Brazil may be on its list in the upcoming years, but not as of right now.

Tesla expands crucial Supercharging feature for easier access

It is a useful tool, especially during hours of congestion. However, it has not been super effective for those who drive non-Tesla EVs, as other OEMs use UI platforms like Google’s Android Auto or Apple’s iOS.

Tesla has expanded a crucial Supercharging feature that helps owners identify stall availability at nearby locations.

Tesla said on Tuesday night that its “Live Availability” feature, which shows EV owners how many stalls are available at a Supercharger station, to Google Maps, a third-party app:

Already offering it in its own vehicles, the Live Availability feature that Teslas have is a helpful feature that helps you choose an appropriate station with plugs that are immediately available.

A number on an icon where the Supercharger is located lets EV drivers know how many stalls are available.

It is a useful tool, especially during hours of congestion. However, it has not been super effective for those who drive non-Tesla EVs, as other OEMs use UI platforms like Google’s Android Auto or Apple’s iOS.

Essentially, when those drivers needed to charge at a Supercharger that enables non-Tesla EVs to plug in, there was a bit more of a gamble. There was no guarantee that a plug would be available, and with no way to see how many are open, it was a risk.

Tesla adding this feature allows people to have a more convenient and easier-to-use experience if they are in a non-Tesla EV. With the already expansive Supercharger Network being available to so many EV owners, there is more congestion than ever.

This new feature makes the entire experience better for all owners, especially as there is more transparency regarding the availability of plugs at Supercharger stalls.

It will be interesting to see if Tesla is able to expand on this new move, as Apple Maps compatibility is an obvious goal of the company’s in the future, we could imagine. In fact, this is one of the first times an Android Auto feature is available to those owners before it became an option for iOS users.

Apple owners tend to get priority with new features within the Tesla App itself.

Elon Musk’s Boring Co goes extra hard in Nashville with first rock-crushing TBM

The Boring Company’s machine for the project is now in final testing.

The Boring Company is gearing up to tackle one of its toughest projects yet, a new tunnel system beneath Nashville’s notoriously tough limestone terrain. Unlike the soft-soil conditions of Las Vegas and Austin, the Music City Loop will require a “hard-rock” boring machine capable of drilling through dense, erosion-resistant bedrock. 

The Boring Company’s machine for the project is now in final testing.

A boring hard-rock tunneling machine

The Boring Company revealed on X that its new hard-rock TBM can generate up to 4 million pounds of grip force and 1.5 million pounds of maximum thrust load. It also features a 15-filter dust removal system designed to keep operations clean and efficient during excavation even in places where hard rock is present.

Previous Boring Co. projects, including its Loop tunnels in Las Vegas, Austin, and Bastrop, were dug primarily through soft soils. Nashville’s geology, however, poses a different challenge. Boring Company CEO and President Steve Davis mentioned this challenge during the project’s announcement in late July.

“It’s a tough place to tunnel, Nashville. If we were optimizing for the easiest places to tunnel, it would not be here. You have extremely hard rock, like way harder than it should be. It’s an engineering problem that’s fairly easy and straightforward to solve,” Davis said.

Nashville’s limestone terrain

Experts have stated that the city’s subsurface conditions make it one of the more complex tunneling environments in the U.S. The Outer Nashville Basin is composed of cherty Mississippian-age limestone, a strong yet soluble rock that can dissolve over time, creating underground voids and caves, as noted in a report from The Tennessean.

Jakob Walter, the founder and principal engineer of Haushepherd, shared his thoughts on these challenges. “Limestone is generally a stable sedimentary bedrock material with strength parameters that are favorable for tunneling. Limestone is however fairly soluble when compared to other rack materials, and can dissolve over long periods of time when exposed to water. 

“Unexpected encounters with these features while tunneling can result in significant construction delays and potential instability of the excavation. In urban locations, structures at the ground surface should also be constantly monitored with robotic total stations or similar surveying equipment to identify any early signs of movement or distress,” he said.
