Has anyone had any experience with "stealing" power from the air? Radiowaves/radiation/etc...
I was thinking of some idea to power a really low power circuit (3.6v, 25nA->90nW) and the name "joule thief" came to my head
When I googled "joule thief effect" I realized it was about to squeeze the last 0.5v-1v from a dead battery, stepping it up to 3 or 5v to power a led or something
What I was thinking of is some sort of coil (+ a rectifier and capacitor) that gathers power enough to generate 90nW. Seems like a small power but I don't really know if its achievable
So I was wondering if anyone has ever experienced with this topic to share his thoughts about it before I try anything (maybe it's just undoable)
