No, no, no, these crystals still need energy to move. They talk about "all you have to do is shine a light on it", yes, that adds energy.
Cool results, but yet another failure of science communication.
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?
in the case of crystals, they vibrate at a fixed frequency and that’s how the clock is driven.
Sure, that makes sense, but it feels like they're implying "energy" when they say "electricity".
