I read power ledger and see no reason for it to become an industry game changer, it looks like it knows only the surface of the industry. Capturing (or storing and reselling) solar energy has been properly done in Europe and even in some parts of South America for a very long time now. In some countries, already there is abundance of energy and people are getting virtually free energy plus some income from selling.
So how is this technology now a game changer when the game has already changed because of it?
Branson for Australia maybe but Elon Musk for something old? Hype and rumours no doubt.
