This is super neat. By modulating the timing of the data being sent to a websocket, (which is basically a /dev/null data sink) it implements a covert air-gaped side-channel data transmission mechanism.

That's the part that's blowing my mind. Energy harvesting is cool and tricky to get right, but it's not magic.

Sending data by modulating the data flow itself, is spooky. Absolute madness. I love it and I'm a little scared.
