The two billionaires connected over Twitter after the head of Tesla’s battery division told ABC the company could solve South Australia’s power problems within 100 days.

Lyndon Rive floated the extraordinary possibility on Thursday: that Telsa could save South Australia’s electricity network by providing 100-300 megawatt hours of batteries within 100 days, to prop up the grid.

But Mr Musk upped the ante after Mr Cannon-Brookes tweeted him to ask “how serious are you about this bet?”, offering to get the money and political support for the plan.

The Telsa founder responded on Friday: “Telsa will get the system installed and working 100 days from contract signature or it is free. That serious enough for you?”

The matter appears to have escalated from there, with Mr Musk tweeting that he had spoken with the South Australian Premier Jay Weatherill and Prime Minister Malcolm Turnbull over the weekend.

Mr Cannon-Brookes called Mr Musk a “legend” and tweeted “you’re on mate. Give me 7 days to sort out politics & funding”. He also asked for a quote for approximately 100MW at “mates rates”.

Mr Musk quoted a price of US$250kWh at the pack level for 100MWh plus systems, about half the original price Mr Rive suggested of US$400-600. That price would have cost about US$50 million (A$66m) for a 100MWh system, making it around A$33 million for Mr Musk’s quote.

Later Mr Cannon-Brookes appeared to suggest he had enough financial support to build as many as 10 of the 100 megawatt hour battery farms.

The Twitter exchange has also seen other companies get in on the act and South Australia appears to be flooded with similar offers.

Zen Energy, based in Adelaide, has also stated it is ready to build a 100 megawatt hour battery farm in South Australia at a cost of $100 million, and which could be online by next summer, according to the Australian Financial Review.

Lyon Solar and Carnegie Energy have also indicated they could help.

Mr Cannon-Brookes tweeted he was “excited to see what comes this week” and he was not the only one.

Prominent Australians as diverse as Father Bob Maguire, The Bachelor presenter Osher Gunsberg and Greens senator Sarah Hanson-Young praised the entrepreneurs for their efforts.

While others marvelled at their speedy response.

Mr Musk thanked Mr Cannon-Brookes and the many other Aussies supporting the plan, saying it could only happen with government support.
