Please forgive my ignorance but the quote you used suggests a clock running without electricity. The article never mentioned it running without an energy source.

I have a tenuous grasp of physics so you could definitely be correct. Can someone with more education on this topic answer if photons can act as an electric current in this experiment?

Sure, that makes sense, but it feels like they're implying "energy" when they say "electricity".

in the case of crystals, they vibrate at a fixed frequency and that’s how the clock is driven.
