Elon Musk's extended ventures; electric cars, space travel, transportation infrastructure to even establishing a colony on Mars. Now he wants to help the battery-powered home industry.
During an earning’s call (disappointing), Mr Musk said his battery 'Gigafactory' division is going to unveil a Tesla ‘home battery’ and he will start going into production by the summer 2015! Probably based on his cars' power packs, they could be used in homes/small businesses, especially those equipped with wind or solar, renwewable power-generating sources. Utilities may embrace his storage system too. Industry rumors of a new gen (pure lithium or sodium metal) 'super battery' in the works.
