An elevator indeed. But there's a cost involved in elevating goods to the top of a tall building. My question was, is that cost smaller than the cost of having drones with elevation capabilities take of from the ground?
- datameta 6y agoPresumably the predominant portion of the energy used to raise an elevator is for the mass of the elevator itself
- saagarjha 6y agoUsually elevators are counterweighted fairly significantly.
- datameta 6y agoAs you say it is actually using very little energy in overcoming the inertia of the system to go up as the counterweight outweighs an empty elevator, and the weight of a drone is insignificant in this regard. However when coming back down the system must raise the heavy counterweight which is only partially balanced by the empty elevator.
