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.
A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.
The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.
There were no injuries reported.

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.
However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.
@Tslachan From on of the videos looks like it’s an old Semi (not the refresh version that recently started production) https://t.co/KzwmR2kXow

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.
The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.
The truck’s driver said that the Semi caught fire, but he did not have an explanation.

Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.
A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.
“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”
🚨 Here’s the first look at Tesla’s Emergency Drive Away function in action:
Apparently this driver accidentally enabled it and drove forward; you can see the Supercharger pull with the car.
Tesla said previously this would cost up to $25k if not used properly. https://t.co/B4qQRrsO6B

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.
Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.
Tesla constitutes the following situations as reasonable justifications for activating the feature:
- You face an immediate threat to your life or personal safety.
- You must leave the area immediately.
- Exiting the vehicle is unsafe.
- Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.
After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.

Tesla’s Cybercab battery design could make robotaxis even cheaper
Tesla built the Cybercab’s battery pack with spare room for a future switch to LFP.
Tesla built the Cybercab’s battery pack with empty space inside it on purpose, and the reason points to a cheaper robotaxi down the road.
Robert Sumpf, Tesla’s director of mechanical design engineering for battery modules and packs, said the extra room beside and beneath the Cybercab’s modules was left there so the company can move to lithium iron phosphate cells later. “So, we protected this pack to go to an even lower energy dense chemistry as we scale and need to bring LFP into the platform,” Sumpf said in a Cybercab deep dive with Munro Live.
The Cybercab runs on Tesla’s own 4680 cells with a nickel chemistry today. LFP cells store less energy for their size, so a straight swap would cut range. The reserved space lets Tesla add more LFP cells to make up the difference. In return, Tesla would get cells that cost less, run cooler and survive more charge cycles. LFP became the most used EV battery chemistry in the world last year.
Not all of that room was planned for a chemistry change. Lars Moravy, Tesla’s Vice President of Vehicle Engineering, said part of it exists because “we didn’t need as many batteries as we thought we did.” Tesla told Sandy Munro in early 2025 that it was targeting a Cybercab pack under 50 kWh with close to 300 miles of range.
The pack also breaks from the structural design Tesla used in some Model Y and Cybertruck builds. Instead of potting hundreds of cells into one block, the Cybercab uses four separate, individually sealed modules, so a bad module can be replaced without scrapping the whole pack. Sumpf was blunt about the older approach, giving the Model Y structural battery “a grade D” because it was hard to build and nearly impossible to repair. He estimated a fully structural pack gains about 10% more cell volume, but said “the issue is the service cost.”
That cost matters more for a car that rarely sits parked. Cybercab chief engineer Eric Earley said replacing an entire pack “before half a million miles is a killer on cost,” which is why remanufacturing and serviceability were built into the design from the start.
The same Munro Live tour produced Moravy’s admission that the Cybercab line at Giga Texas is now outpacing Robotaxi deployments, along with a look at the robotaxi’s unorthodox paint process. Tesla is aiming to deliver the first Cybercabs to outside customers by the end of 2026, though Elon Musk has said the vast majority will stay owned by Tesla and run as a transport service.
Sumpf did not give a date for an LFP version, name a cell supplier or say how a chemistry change would affect range. For now, the 4680 cars keep piling up: Texas DMV records from Tuesday list 544 Cybercabs authorized for Tesla’s Robotaxi fleet, more than the 507 Model Ys on the same roster for the first time.
