Well, no. It's working by grabbing energy off power lines. Basically the same thing as a wireless charger (or indeed, a transformer). Would probably work pretty well if you lived close to a 120+ kV transmission line.

Ouroboros in Greek mythology is the serpent (or sometimes a dragon) that lives by eating its own tail.
