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 battery, I strive to maximize electrical potential. When mentoring, I strive to maximize human potential.

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?

The liquid metal battery story is more than an account of inventing technology. It's a blueprint for inventing inventors.

If you want to make something dirt cheap, make it out of dirt–preferably dirt that is locally sourced.
