“Not only can today’s technologies cut elevators’ energy use, but they also can return energy to the building grid.”
Breaking is broken, from lifts to electric trains, cars to pushbikes, applying breaks is simply swapping useful energy for bad useless energy, ie entropy. So it goes!
Not new, a but cool idea.
Loving these magnetic elevators- that can go sideways too like a tube.
