Here’s everything you need to know about the Boring Company

Elon Musk is best known for Tesla electric cars and SpaceX. But his new tunnel-making venture, aptly named “The Boring Company,” wants to revolutionize the way that Americans travel — not up in powerful space rockets this time, but rather beneath our cities. Here’s everything you need to know.

Why is Elon Musk obsessed with tunnels?

In the words of the Boring Company, “roads must go 3D.” Musk and his company believe that going underground is a better choice than mass air travel. “Going up” in flying cars will create a whole new set of problems including noise, weather concerns, and the safety of pedestrians below them. With tunnels, traffic is pushed underground, limiting noise and preventing the division of communities that a large multilane highway exacerbates.

Construction of these tunnels is all but invisible to those on the surface, and the Boring Company argues that as more capacity is needed, a new tunnel can be built to address it. He likes the idea of tunnels because they’re long-term, they won’t have much impact on current city structures, and (naturally) because it’s a little sci-fi. It also ties in well to Musk’s high-speed, long-distance transit passion (including dreams like the Hyperloop), and the possibility of connecting nearby cities to each other.

The Boring Company was founded to look into ways of making underground tunnel construction more feasible.

So, what is The Boring Company exactly?

Humans have been digging underground tunnels for thousands of years, so at face value Musk’s idea seems a little bit silly. Why would a man who’s spent many years working on next-generation technologies focus on something we already do well? The simple answer is efficiency.

We might be able to construct tunnels better than we have in the past, but that doesn’t mean we do it efficiently or in a cost-effective manner. A great example of this was Boston’s so-called “Big Dig,” which pushed most of the highway systems through downtown Boston into tunnels. Inefficiencies and cost overruns inflated the cost of that project to $22 billion, and it took 15 years to complete. even worse, the end product was of questionable quality, even though it has had a generally positive effect overall.

The Boring Company hopes to prevent construction nightmares like the Big Dig. It’s not reinventing the wheel; what’s different here is they’re using old-fashioned underground digging more efficiently. Specifically, the Boring Company aims to vastly increase the speed at which tunnels can be dug and at a far cheaper rate than is now feasible. It will help dig the tunnels itself, using its own assets — with a bit of high-tech thrown in.

What does The Boring Company do differently?

The Boring Company focused on several areas of tunnel digging to improve the process overall. Some of the advancements include:

  • New TBMs (tunnel boring machines): Current TBMs operate very slowly — about 14 times slower than the movement of s snail, the Boring Company says. It is developing a brand-new TBM that is still slow (only marginally faster than a snail) but will dramatically decrease digging time. The new TBM operates with electricity and with three times the power.
  • New support strategies: Currently, TBMs spent about half their time tunneling, and the other half building supports. The Boring Company wants to develop a way for its TBM to do both at the same time.
  • Smaller tunnels: Tunnels built by the new TBM are only 14 feet wide, half the size of modern one-lane tunnels. As a result, tunneling becomes three to four times cheaper.
  • R&D: No research and development has occurred in tunneling in nearly 50 years. The Boring Company plans to invest significant resources into developing new methods and equipment to further speed up the process.

What current projects is The Boring Company involved in?

Musk and the Boring Company have been doing real tunneling work for the better part of two years now. Construction of a small test tunnel wrapped up in June 2017, however it wasn’t ready for a public demonstration until December 2018. That tunnel is 1.14 miles in length.

The company did have plans to build a second tunnel that ran parallel with the 405 freeway (beneath Sepulveda Boulevard) along Los Angeles’ west side, but it was scrapped after community pushback. Other projects are still underway, including some pretty crazy ones.

The company proposed a loop system in August 2018 that would shuttle Los Angeles Dodger fans and concertgoers from the Los Feliz, East Hollywood, or Rampart Village neighborhoods to Dodger Stadium. The total trip is expected to cost passengers just $1 to ride, and would get them to the stadium in 4 minutes. Currently in the environmental review and permitting stages, no date for construction or opening has been set. Construction is expected to take less than 14 months.

It also was selected by the Chicago Infrastructure Trust to “design, build, finance, operate and maintain” an O’Hare Express loop service. This system will  connect Block 37 in downtown Chicago with O’Hare Airport Terminals 1-3.

Perhaps the biggest and most ambitious project is a proposed tunnel connecting Baltimore with Washington D.C., which would allow individuals to travel between the two cities in about 15 minutes. Construction of the tunnel is expected to take between 12 and 20 months depending on the speed of the TBM. The long-term goal is to build a tunnel between New York City and D.C. The trip is expected to take only 30 minutes.

Many of these projects currently are not much more than proposals, but a few have begun, and Tthe Boring Company is going to be busy for the foreseeable future.

What issues still need to be addressed?

There are a number of issues with digging new transportation tunnels, some that the Boring Company has addressed and some it has not. They include:

  • Earthquakes and vibrations: The Boring Company assures people that its tunnels are too deep for any meaningful vibrations to be felt. It maintains that tunnels don’t really get damaged in earthquakes, and can’t cause them, so it doesn’t consider this an issue.
  • Dirt: The Boring Company has developed technologies that allow it to recycle the dirt from digsinto bricks and paving stones. It even is looking for ways to use these bricks for a portion of the tunnel lining.
  • Emissions: The company uses an electric skate method to transport gas-burning equipment (unfortunately, tunneling equipment needs a lot of power and cannot be fully electric yet). This helps cut down on at least some emissions involved in the process. Presumably, once tunnels are completed, they will be equipped with electric cars and vehicles.
  • Size: Fourteen-foot tunnels are small, and primarily have been used for sewer and stormwater projects in the past. A lot of work is left to be done in developing cars and a transportation equipment that can be used in these smaller tunnels. The company has offered some interesting mock-ups in the past. But would these new tunnels be required to use Boring Company vehicles?

If you live in NYC, D.C., or another city riddled with public transit, you have probably noticed (especially in recent years) that the big problem with subways and similar solutions is maintenance. Tunnels may reliably stay the same, but underground equipment wears out very fast and is very difficult to replace or keep running on a reliable schedule over time. In other words, you can have the best tunnels in the world, but unless the city devotes enough resources to maintenance and updates, they are going to run into a whole lot of problems.

Digital Trends’ Tech For Change CES 2023 Awards
Digital Trends CES 2023 Tech For Change Award Winners Feature

CES is more than just a neon-drenched show-and-tell session for the world’s biggest tech manufacturers. More and more, it’s also a place where companies showcase innovations that could truly make the world a better place — and at CES 2023, this type of tech was on full display. We saw everything from accessibility-minded PS5 controllers to pedal-powered smart desks. But of all the amazing innovations on display this year, these three impressed us the most:

Samsung's Relumino Mode
Across the globe, roughly 300 million people suffer from moderate to severe vision loss, and generally speaking, most TVs don’t take that into account. So in an effort to make television more accessible and enjoyable for those millions of people suffering from impaired vision, Samsung is adding a new picture mode to many of its new TVs.
[CES 2023] Relumino Mode: Innovation for every need | Samsung
Relumino Mode, as it’s called, works by adding a bunch of different visual filters to the picture simultaneously. Outlines of people and objects on screen are highlighted, the contrast and brightness of the overall picture are cranked up, and extra sharpness is applied to everything. The resulting video would likely look strange to people with normal vision, but for folks with low vision, it should look clearer and closer to "normal" than it otherwise would.
Excitingly, since Relumino Mode is ultimately just a clever software trick, this technology could theoretically be pushed out via a software update and installed on millions of existing Samsung TVs -- not just new and recently purchased ones.

AI turned Breaking Bad into an anime — and it’s terrifying
Split image of Breaking Bad anime characters.

These days, it seems like there's nothing AI programs can't do. Thanks to advancements in artificial intelligence, deepfakes have done digital "face-offs" with Hollywood celebrities in films and TV shows, VFX artists can de-age actors almost instantly, and ChatGPT has learned how to write big-budget screenplays in the blink of an eye. Pretty soon, AI will probably decide who wins at the Oscars.

Within the past year, AI has also been used to generate beautiful works of art in seconds, creating a viral new trend and causing a boon for fan artists everywhere. TikTok user @cyborgism recently broke the internet by posting a clip featuring many AI-generated pictures of Breaking Bad. The theme here is that the characters are depicted as anime characters straight out of the 1980s, and the result is concerning to say the least. Depending on your viewpoint, Breaking Bad AI (my unofficial name for it) shows how technology can either threaten the integrity of original works of art or nurture artistic expression.
What if AI created Breaking Bad as a 1980s anime?
Playing over Metro Boomin's rap remix of the famous "I am the one who knocks" monologue, the video features images of the cast that range from shockingly realistic to full-on exaggerated. The clip currently has over 65,000 likes on TikTok alone, and many other users have shared their thoughts on the art. One user wrote, "Regardless of the repercussions on the entertainment industry, I can't wait for AI to be advanced enough to animate the whole show like this."

The fitness world is littered with opportunities to buy tech aimed at enhancing your physical performance. No matter your sport of choice or personal goals, there's a deep rabbit hole you can go down. It'll cost plenty of money, but the gains can be marginal -- and can honestly just be a distraction from what you should actually be focused on. Running is certainly susceptible to this.

A few months ago, I ran my first-ever marathon. It was an incredible accomplishment I had no idea I'd ever be able to reach, and it's now going to be the first of many I run in my lifetime. And despite my deep-rooted history in tech, and the endless opportunities for being baited into gearing myself up with every last product to help me get through the marathon, I went with a rather simple approach.
