Could maybe be made low enough power that it can power itself via ambient light (like an old school calculator) or radio waves.

- BobaFloutist 2y agoThat would be cool, but I haven't actually seen it in anything other than an old school calculator so I assume the limitations are pretty significant.
- wiml 2y agoI've seen energy-harvesting remote light switches for sale — they supposedly get enough energy from the physical act of flipping the toggle to send a few radio packets. I haven't used one in the real world though.
