I mean yeah obviously thermodynamics aren't being violated, I think the base idea is that the background noise you're harvesting from was going to be lost as inverse square law losses anyway. Large amounts of sensors would ultimately be as a whole coupled to antennae broadcasting on those frequencies, damping them, and causing the gain circuits to automatically increase output power.
