Attached: 1 image Wow. Did you know this? There exist *power over fiber* components that can provide 3v 180mA from 1.5W of 800nm infrared light coming through a standard multimode optical fiber. These are very expensive, but also very cool! https://www.farnell.com/datasheets/2785190.pdf

This Mastodon post hit #1 on Hacker News today, I think people around here would be interested.

Then you look at the $350 price point and walk away.

    Maybe not miles. Even in Fiber Optics, there is a degree of attenuation / power loss as the cable absorbs some light and emits it as heat. But you might get a good enough distance before enough energy dissipates.
