On Twitter, Musk often employs a wry sense of humor, battles with rivals and critics and offers critiques of the media.
On Friday, he offered a creative idea: Insert a tube through the cave network that could then inflate, displacing water and creating an air pocket for rescuers to bring the children through.
Elon Musk's companies could help by trying to locate the boys' precise location using Space Exploration Technologies or Boring Company technology, pumping water or providing heavy-duty battery packs known as Tesla Powerwalls, a spokesman for the billionaire said.
Musk has been following the story of the soccer team, tweeting his thoughts and offering to assist the Thai government in any way he could over the past week.
Some of the kids have also indicated they can not swim and are already weak from not eating. Heavy rains are forecast for this Sunday, and the boys are now being trained in the use of scuba diving gear while the Thai Navy Seals prepare the 5km-long route for their anticipated evacuation.
Chaiyaporn said he would prefer to see the floodwater subside to a much lower level to enable the boys to get out safely, but that chance was relatively low as the rainy season has only started. Divers have been teaching them diving and breathing techniques.
They had gone missing on June 23.
So far, around 1,000 people have got involved in the rescue operations..
Authorities are now pumping water from the cave before forecast rain hits the northern region tomorrow.
Among his tweets about the rescue, he also said: "But let's not submit to the bad mood entirely". They were ultimately found by rescuers 10 days after originally becoming trapped in the cave, and luckily, only "light injuries" have been reported in the group. Suttisak said the Tham Luang cave being totally natural, there is not enough geological data for engineers to work out a solution.
