The Thai soccer team has been stuck in the cave since June 23.
The engineer threw out some measurements about the cave and drills needed, to which Musk answered with a suggestion of a new way to try to drill that involved inflating "air like a bouncy castle". The approach would require much less power than pumping water out of the cave chambers. Rescuers have been working on a variety of plans, including teaching the boys to scuba dive. Thai diver Saman Kunan, 38, died around 1 a.m. local time while placing oxygen takes deep underground as a lack of oxygen becomes and increasing concern for those stranded.
The dive is also dark and risky - it has taken rescuers six hours to reach the team and another five hours to return to the entrance.
Thai Navy SEALs have attended to the group inside the cave, providing them with high-protein drinks and treating minor injuries.
The Thai government confirmed on its Facebook page that Musk's engineers will begin assisting the rescue mission on Saturday, when more heavy rains are expected to complicate the already extremely delicate operation. He began by touting Boring Company's "advanced ground penetrating radar" and suggested that if his tech could help, he could "dropshop fully charged Powerpacks and pumps".
Musk's tunnelling startup the Boring Company could potentially make available its massive drills or excavation expertise, but such an approach could be too unsafe for this mission.
Musk floated the idea of inserting a nylon tube through the underwater passageways for the boys to walk through.
