Elon Musk has perhaps the most exciting portfolio of businesses on the planet.
There’s SpaceX with its mission to Mars, and Tesla with its super-fast hi-tech electric cars.
He claims his Hyperloop concept could revolutionise public transport. And even his Boring Company is kind of interesting – it aims to find new ways to dig tunnels.
So which one will end up changing the world most? It is my contention that it will be his battery business.
Doesn’t sound that scintillating does it?
