There are already superconducting circuits that are used in quantum computers and other high end applications, but they're not ubiquitous. So we could get electricity into a battery if you had a superconducting battery and it would cycle forever. And again, this will lead to infinite energy storage in batteries. I'm really excited to have Ray Dali. We've got a few other guests that were not going to announce that will be last minute fun surprises for everyone.
