Certainly atoms in solids can vibrate, and increasingly so with heat, but they're fixed in position relative to each other. Except for ions in electrolytic capacitors and batteries, PoW is not moving atoms in electronic circuits.
As I said it was more of a quibble than anything..I was probably just looking for an argument.

That being said, maybe my understanding of physics is not correct.
https://en.wikipedia.org/wiki/Absolute_zeroThe fundamental particles of nature have minimum vibrational motion, retaining only quantum mechanical, zero-point energy-induced particle motion.
