Via the full Twitter thread, Musk discussed potential options for the endeavor, speaking of inserting a 1m diameter nylon tube "through the cave network" in an attempt to "inflate with air like a bouncy castle".
Last year, after a devastating hurricane hit Puerto Rico, the government there asked Mr Musk for help. Over the years, he has also used social media to respond to global disasters.
Musk is also offering rescuers technology from his tunnel construction company including equipment used for location tracking, water pumping and powering batteries.
However, the dive is complex - with one Navy SEAL dying during the rescue efforts - and numerous boys do not know how to swim.
The tech entrepreneur has taken to Twitter suggesting an underwater air tube which could be created for the children to crawl through.

He said the Tham Luang challenge is unique - unlike any other rescue effort around the world - especially in terms of the number of young people trapped inside a complicated cave network.
12 boys and their coach have been trapped in one of the caves in the Tham Luang complex in northern Thailand for 13 days now.
The attempted rescue from the Tham Luang cave complex has proven hard and deadly. "If Elon says it will work hopefully it will", said Bell.
