“recycles the energy it creates from friction while braking” gives the impression that regenerative braking involves friction. Friction is the wasteful way to brake and the elevator companies avoid it through regenerative braking, which is way cooler than conventional braking by friction.

Good to know there is some good work going on out there in the midst of this historic and contentious energy transition. I want a pimped out elevator!
