Apr 18, 2019 at 9:13 comment added Ruadhan I kinda like this idea, imagining a cyberpunk city where there's just so much excess EM around that people are using it as a supplementary energy supply :P
Apr 16, 2019 at 14:07 comment added Aubreal I don't think you know just how small the received power is. For example, my phone is currently receiving -52dBm of power from my router through my wifi connection. This translates to 0.0000000063 Watts. This is actually quite a high amount for a wifi signal, I'm fairly close to the router. For a sense of scale, a typical quartz wristwatch runs off roughly 0.0002 Watts of power, and that's one of the lowest-power everyday items most people have. Harvesting power from electromagnetic signals meant for telecommunications is futile.

Apr 16, 2019 at 13:30 comment added Aubreal The power received by antennas for the purpose of telecommunication is incredibly small. This won't work.
