The World’s Biggest “Battery” Isn’t a Battery

What keeps Physics Girl moving in a week with no new uploads? Energy storage, as it happens. "The World's Biggest “Battery” Isn't a Battery" is part three of Dianna Cowern's renewable energy road trip, in which she talks to scientists and engineers working on the old problem of wind and solar power that does not arrive on schedule. At eight days old it is past half a million views and carrying far more of the channel's momentum than anything else in the catalog.

Behind it sits "My first science video in 3 years!", the return that opened with a photo supposedly taken at night. Six months on, it is close to a million views. That title carries weight: Cowern stepped away for years, and the video marked her coming back to the work. A fifteen-day-old explainer on time crystals, "BREAKING: A New Phase of Matter," has quieted down.

The subscriber count held still. Among science channels of similar size, Physics Girl is third by subscribers, and the busy ones right now are Hank Green and Steve Mould, both running well above their usual pace.
