Is “harvesting” small amounts of electricity a fools errand?

Serious question from a beginner in electronics. For reasons I do not fully understand, I have become fixated on the idea of collecting small amounts of electricity from “interesting” sources. I don’t mean “free energy”, instead, I mean things like extracting a few mV from being so close to a AM radio tower using two...

rarely,

Fantastic, thanks! I’ll take a look

rarely,

I guess the difference for me would be how long it stores that energy for, but the difference is probably semantic and easily changed with a few capacitors.

Oh yeah, I hear you on LLMs. Technically, ChatGPT has not “heard” of anything. It’s generally something I use as a jumping-off point when I’m desperate and don’t know what search query to use.

Does passive RFID harvest its power? I don’t know much about RFID (I’ll probably head over to wikipedia after this comment) but I figured that it was a circuit that, when given a bit of energy from a reader, sends back an RF signal with an encoded ID and that in the absence of that powered reader, the RFID device wouldn’t be transmitting anything.

Oh yeah, i’ve seen that before! I’ll need to try to make one of these as well. Looks like a fun experiment!
