Earlier this week, Musk offered engineers from two of his other companies — SpaceX and The Boring Company — to assist the Thai government. The video shows three people in scuba gear pushing and pulling the tube across a pool.
One video that Musk tweeted shows the submarine being lifted out of the pool and a person popping out of the submarine completly dry.
Another video shows the submarine underwater for 35 seconds
Sam Teller, the spokesperson for the Boring Company, said four company engineerswere "offering support in any way the government deems useful."
Musk first tweeted about the boys trapped in the cave on July 4 after somebody asked him if he would assist. He wrote that he would be "happy to help if there was a way to do so."
I suspect that the Thai govt has this under control, but I’m happy to help if there is a way to do so
Musk then started brainstorming ideas to help via tweet. On Friday, he tweeted that "SpaceX & Boring Co engineers heading to Thailand tomorrow to see if we can be helpful to govt."
In one tweet, he suggested that a tube or series of tubes be sent through the cave network and inflated, creating a tunnel for the team to travel through without needing to scuba dive.
On Saturday, Musk tweeted that he was interested in designing "a tiny, kid-sized submarine" that would be "light enough to be carried by 2 divers, small enough to get through narrow gaps."
In later tweets, Musk said that the submarine he is working on has four handles in the front and four in the rear, along with four air tank connections. He also confirmed that the device could maneuver through the most narrow passages.
Eight members of the soccer team, ages 11 to 16, and their 25-year-old coach remain trapped in the cave. Officials said the rescue could take four days to complete. The team has been trapped in the cave for two weeks.
