Elon Musk will send engineers from SpaceX and Boring Company to Thailand to see if they can help rescue the junior football team trapped in a cave.
The twelve boys and their football coach have been underground since June 23, with the exit passages blocked by water after rainfall.
Monsoon rains are expected at the weekend, which could leave the football team, aged 11-16, and the coach trapped for months.
A Twitter user asked Elon Musk if he could help with the rescue attempts, and he responded with various ideas.
He said that The Boring Company, his tunnel and infrastructure company, had an “advanced ground penetrating radar & is pretty good at digging holes”.
James Yenbamroong, a Thai tech entrepreneur and founder of muSpace Corp, a satellite communications organisation, replied to the tweets saying Mr Musk’s company SpaceX had been in touch and he’d connected them with the Thai government.
Mr Musk then suggested that inflatable tubes could be inserted into the cave to help pump the water out, before announcing that engineers would go to the Tham Luang caves in the Chiang Rai province tomorrow (June 7) to see if they could help.
Rescuers are already trying to pump water out, and Sky News Asia reporter Alex Rossi, who is at the scene, said “around 40% of the water has now receded - about 1.5km - a bit less than a mile into the cave”.
"They are trying to get more of that water out so that those boys can scramble out, walk and perhaps do a little diving,” he added.
A former Thai navy SEAL died in a rescue attempt after running out of oxygen.
Some sections of the cave, including a narrow passage in the middle, are still filled with water from floor to ceiling, meaning the boys currently have no option but to dive through some sections.
Thai navy SEALS were teaching them to dive earlier in the week.
