Answering Elon Musk’s call for help to build Thailand’s cave rescue pod in 24 hours
On the morning of Friday, July 6, Andrew Branagh received a call that would put his company’s 30-year experience in the field to the test. Branagh, who serves as the CEO of Arcata-based Wing Inflatables, had been asked by Elon Musk’s engineering team from SpaceX to construct an inflatable escape pod for the 12 children and their coach who are currently stranded in an air pocket inside the sprawling Tham Luang Nang Non cave complex in Thailand. Knowing that time is of the essence, Branagh and his team got to work.
The stranded members of the Wild Boar Soccer Team have been stranded in the caves since June 23, after a casual excursion into the underground caverns turned into a pitch-black ordeal due to flash floods. The group of 13, comprised of boys aged 11-16 and their 25-year-old coach, were missing until this past Monday, when they were located by two UK divers. The children and their coach have been given food and survival supplies, and on Tuesday, a doctor and a nurse spent the night with them. While the group is safe for now, however, retrieving them is not easy, considering that they are located 2.5 miles away from the entrance to the caves. Parts of the cave systems are also underwater, which would force the children to dive into murky waters during their retrieval.

In a tweet on Friday, Elon Musk posted a brief update on Twitter stating that SpaceX and Boring Co. engineers are headed to Thailand in order to see if they can be helpful to the government’s rescue efforts. That was the same day that Branagh woke up to a text and call from the SpaceX team. Branagh notes that the message was brief, but the request was clear.
“Elon has an idea, or our team does.”
Musk’s initial idea to rescue the trapped children is to use an inflatable tube. Considering Wing’s experience in the field, Branagh and his team went to work refining the idea. The result was a submersible “torpedo,” which could hold a person with an air tank and a breathing apparatus. The torpedo is designed to be towed by its front and back, and be sleek enough to be guided through the cave system’s trickiest sections. Branagh opted to utilize 30% of his company’s workforce for the fast-track effort, reducing his business’ usual output by half. The CEO’s gambit worked, and by 9:30 a.m. on Friday, a prototype was ready. Branagh noted that the first rescue pod, which is 7-feet-long, sealed with velcro, and inflatable with the passenger’s exhaled air, was a finished product. There were no throw-away units or re-dos. There was just not enough time.
By 1:00 p.m., Wing’s rescue pod was tested on the Arcata Community Pool, with a certified dive instructor and two individuals who do not know how to swim. The tests were encouraging, with both test individuals being able to breathe comfortably inside the rescue pod. Branagh had also been speaking with Musk and his engineering staff in a conference call.
“He (Elon) was very direct and clear on supporting getting a solution in place,” Branagh said.
By 5:15 p.m., the first set of Wing Inflatables rescue pods were ready to be transported from Arcata-Eureka airport in Northern CA.
Apart from the inflatable pods that the engineers from SpaceX and The Boring Company transported to Thailand on Friday, Musk and his team at LA are also designing a mini-submarine for the children. In a series of tweets over the weekend, Musk stated that the mini-sub would be small enough to fit through the contours of the cave and its hull will be made of the same material as the oxygen transfer tube of a Falcon rocket, making it extremely durable. The mini-sub would have four handles and hitch points for the front and rear, with two air tanks on both front and rear, allowing up to four tanks to be connected.
Given Chiang Rai airport hours, soonest we could’ve departed US was an hour ago, but cave now closed for diver rescue. Will continue testing in LA in case needed later or for somewhere else in future.

Rescue efforts for the stranded children are already underway as of Sunday. For this rescue attempt, the children would have to dive using scuba gear into the waters with two experienced divers. Divers who will be conducting the retrieval of the soccer team are expected to spend 11 hours inside the caves, six hours heading to the children, and five hours going out. It remains unknown for now if the rescuers will be utilizing the rescue pods delivered by the SpaceX and Boring Co. team. Musk’s mini-sub continues testing in LA, just in case it’s needed for the cave rescue efforts.
Tesla is continuing to push the boundaries of vehicle dynamics, as its latest published patent, US12654505B2, or “Suspension Actuator System for a Vehicle,’ which has finally been pushed through.
The design, which is credited to inventors Brian Lee Doorlag, Avraham Kagan, and Justin Sill, introduces a sophisticated hybrid suspension design that blends active motor-driven control with strategic passive elements to deliver superior ride quality, energy efficiency, and resilience against road imperfections, especially potholes.
Suspension Actuator System for a Vehicle@Tesla‘s US20240383297A1 patent introduces an innovative suspension actuator system that transforms vehicle suspension control through an intelligent combination of active and passive control elements.

At the heart of the system is an active control element powered by an electric motor. This motor drives a belt connected to a ball nut assembly and threaded screw, which adjusts the effective length of the suspension strut in real time.
By extending or retracting, the actuator can lift or lower the wheel more accurately, which can end up countering road disturbances. Sensors, including accelerometers and wheel position monitors, feed data to a suspension control system that processes inputs and commands the motor instantly.
This active component doesn’t work alone. A low-rate air spring mounts in parallel with the actuator. Its primary role is to offset much of the vehicle’s static weight, dramatically reducing the power demand on the motor.
Without this, the active system would constantly fight gravity, draining energy and generating heat. The air spring handles steady-state loads efficiently, allowing the motor to focus on dynamic adjustments.
Complementing this is a series of passive control elements—a spring and an adaptive damper—placed between the actuator and the wheel. This setup filters high-frequency vibrations before they reach the active motor, preventing it from overworking on minor inputs. The adaptive damper, potentially magnetorheological or valve-controlled, further tunes damping electronically for optimal comfort and stability.
How It Differs from Traditional Suspensions
Traditional passive suspensions compromise between comfort and handling, while pure active systems can be power-hungry and complex. Tesla’s hybrid approach resolves this by delegating tasks: the parallel air spring manages weight and low-frequency body motions, the series elements absorb rapid vibrations, and the active actuator tackles larger, lower-frequency events.
The result is a smoother, more isolated cabin experience. High-frequency road noise and harshness diminish, while the vehicle maintains precise control during cornering or acceleration. Energy efficiency improves, too—lower motor loads mean reduced battery drain, potentially extending range in electric vehicles.
How It Mitigates Potholes Specifically
Potholes are a major challenge because they provide a sudden drop to the wheel plunge, jarring the body of the vehicle, risking damage. The patent explicitly addresses this. Upon detecting a pothole (via sensors or predictive mapping), the control system activates
the motor to retract the strut, effectively pulling the wheel upward to minimize downward excursion. The series spring/damper cushions the impact, while the parallel air spring maintains overall support.
This proactive “wheel retraction” prevents sharp jolts, preserving passenger comfort and protecting components. Integrated with Tesla’s road roughness mapping patents, the system could anticipate potholes from fleet data, enabling preemptive adjustments for even smoother navigation.
Future Implications for Tesla Vehicles
This technology builds on Tesla’s existing adaptive dampers and air suspension that is seen in Cybertruck, but advances toward fully active control. It could roll out to future models, including refreshed Cybertrucks or next-gen vehicles, enhancing both daily drivability and off-road capability. By minimizing power use and complexity, it aligns with Tesla’s goals of efficiency and scalability.
In summary, US12654505B2 exemplifies Tesla’s engineering philosophy: intelligent integration over brute force. This hybrid suspension promises quieter, more comfortable rides and robust pothole defense, potentially setting a new standard for automotive comfort. As Tesla iterates, drivers can look forward to roads feeling far less rough.
The Tesla Cybercab got a huge nod of support from a Texas Department of Transportation official, who said the all-electric ride-hailing vehicle is “a tangible example of how quickly our transportation system is evolving.”
The Cybercab was present at the Texas Department of Transportation’s Texas Innovation Invitational, an event held each year that allows innovative companies to showcase advancements in transportation.
Tesla Cybercab specs revealed: range, curb weight, range ratings, and more
Marc Williams, the Texas Department of Transportation’s Executive Director, sat in a Cybercab and shared his thoughts in an extensive post on LinkedIn.
Williams’s comments show how Tesla, with its Cybercab, is leading the charge of passenger travel and how it’s changing so rapidly. He notes the absence of traditional driving controls as a telltale sign that the Cybercab is a catalyst for major automotive change, taking controls from drivers and turning them into full-time passengers.
“Observing this vehicle firsthand–from its design and butterfly doors to the cargo trunk configuration–provides a tangible example of how quickly our transportation system is evolving. Sitting inside the cabin, the complete absence of traditional driver controls underscores a significant shift in mobility and vehicle design. No steering wheel, no accelerator, no brake. Only a single touchscreen monitor.”
Tesla has had a great relationship with the State of Texas, especially with its Robotaxi ambitions. Currently, Texas has Tesla Robotaxi operating in multiple cities: Dallas, Austin, San Antonio, and Houston. The company’s main manufacturing plant is also located just outside Austin, and Tesla moved its headquarters to the state several years ago.

The Cybercab is a purpose-built, fully autonomous, two-passenger Robotaxi vehicle designed specifically for ride-hailing services. Tesla has said for years it would be built without a steering wheel or pedals present, although there is still quite a bit of debate among the community regarding that potential.
Earlier this week, we received official word that the EPA had provided the Cybercab with a Certificate of Conformity, giving Tesla permission to enter the vehicle into the chain of public commerce. It is officially ready for roads.
The big question for Tesla remains: Can it solve self-driving before the steering-wheel-less Cybercab officially enters production?

The Boring Company just doubled its tunneling power in Nashville
The Boring Company’s Prufrock MB2 is commissioned and ready to mine beneath Nashville’s streets.
The Boring Company’s second tunnel boring machine, Prufrock MB2, is officially ready to dig in Nashville. The company confirmed the news on X, posting: “Prufrock-MB2 is ready to mine in Nashville! MB2 commissioning is complete, including the brief 11 rpm rotation shown here. Will MB2 catch up to MB1, who had quite the head start? And Prufrock-MB3 ships in August!”
MB2 arrives with meaningful improvements over its predecessor. Lessons learned from the launch and operation of MB1 have already been applied to MB2 to improve efficiency and prepare the machine for launch.
Traditional tunnel boring machines operate in a stop-and-go cycle, digging roughly five feet, halt, erect precast concrete segments to line the tunnel wall, then resume. That repeated interruption is one of the main reasons conventional tunneling is slow and expensive. Prufrock is designed to install the tunnel liner simultaneously with mining, eliminating the need to stop every five feet. The machine also skips the need for excavated launch pits. Prufrock arrives on a truck, tilts down, and launches into the ground within 24 hours. And when the tunnel is complete, it emerges from the ground and drives to its next launch site on a trailer, eliminating the need for expensive cranes or pit excavation. The machine is also fully electric and runs with zero people in the tunnel during normal operations, controlled remotely from a surface operations center.

It won’t be long before we hear of another major update on The Boring Company’s Music City Loop project – a planned underground transit network beneath Nashville that would move passengers in electric vehicles through a series of tunnels at highway speeds, and bypassing surface traffic entirely. Nashville was selected in part because of its strong rock conditions that suits the Prufrock machines well, and relatively less regulatory hurdles.
Progress has been steady on multiple fronts. All 37 permits and approvals required ahead of tunneling have been obtained, out of 45 total. Key wins include a fully executed TDOT tunnel permit authorizing 25 miles of tunnel, unanimous airport authority approval for a Nashville International Airport station, and the city’s first residential station agreement serving downtown tower residents.
With MB1 already tunneling, MB2 now commissioned, and MB3 shipping in August, Nashville is becoming something of a live proving ground for scaled tunnel boring. The broader ambition is not limited to one city. The Boring Company’s stated goal is to make underground transportation a practical alternative to surface roads across major metro areas. Nashville is one of many cities, including a successful Las Vegas tunnel system, where that idea is being put to the test at real speed.
