It’s a closed system, self-powered desktop scanner.
The scanner is plugged into your computer as normal, by USB.
You feed your paper into the scanner, which is also a shredder. The paper is shredded and falls through the desk, where it lands in a compost heap, which is fills with mulch and worm. The worms digest the paper and, as you know, release methane. The methane is burned, a turbine turned, and a battery charged… into which is plugged the scanner.
The scanned data proceeds to the computer.
This is good so long as you only need to scan whatever you have once. And you don’t mind having a bucket of worms under your desk.
