I love this. I think of it as a 4-hour uninterruptible power supply for 20,000 homes. Not mentioned in the article but it’s also a way to “time shift” power consumption from other sources. Not unlike Tesla’s powerwall, which is primarily intended to make solar more practical, and yet also serves as a kind of UPS as well. Oh, and this came in cheaper, and earlier than expected. 🙂

If it ever happens an economic rechargeable battery (like we have in cars) that doesn’t wear out, will be one of the greatest inventions of man. It will serve the rich and the poor of the world.
Totally agree – battery technology has the potential to really be a game changer.
