I suppose "noise" requires a more precise definition here – I assume they don't mean a thermal background. Or otherwise I'm left wondering how this squares with the Second Law of Thermodynamics: You start with high entropy (thermal noise) and end up with low entropy (a charged battery)?
- iancmceachern 3y agoIt's like when your windows vibrate when you turn up the bass. The energy comes from the amplifier, it's being put into the ether by the woofer, and then the window pane collects it. Energy is neither created nor destroyed. The thing is, we don't have general purpose "windows" in this EM world, until now.
- codethief 3y agoYes, exactly, you are talking about a coherent bass tone (sine/cosine) for which the window happens to be resonant. This energy can be extracted of course. Thermal noise is not a tone, though.
- iancmceachern 3y agoYes, but EMI noise is (Its called frequency). Which is the mechanism by which the the Sony module in question operates. It's weird for yoi to bring up thermal "noise". What you are referring to is thermal decay, entropy. Yes, you can harness this too, but it's a different mechanism and not really pertinent here.
