Comment on Physicists Build Circuit That Generates Clean, Limitless Power from Grapheneparent

This does sound promising. Is it possible to run this process in reverse a la a heat pump to create an AC with no moving parts? Or is this purely a one way process?

I'd say Joule heating is the reverse of this process: https://en.wikipedia.org/wiki/Joule_heating#Microscopic_desc...

Peltier coolers are probably in line with what you're suggesting, but they're not super efficient.

I was hoping for an alternative to those. They are neat but with such low efficiency they aren’t super useful.
