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.

      It’s power over light. You’re gonna lose some of it.

      It’s incredible you can do this at all really.

        $350 and 30% efficient today, $3.50 and 90% efficient* in a decade. Gotta start somewhere.

        Not an actual prediction of future price and performance in case someone starts looking at the second set of numbers. Just saying if it works well enough to be sold to home users, I expect continued development and production lines to have an impact. Also does not account for inflation.
