With a giant battery, we'd be able to address the problem of intermittency that prevents wind and solar from contributing to the grid in the same way that coal and gas and nuclear do today.

In a wristwatch, imagine the battery is in the strap and there's a medical sensor in there connected to the internet. If someone is monitoring that, they could phone up if the user has forgotten to take some medication. This could save hundreds of dollars in medical fees later. What's missing? It's a stable battery.
