I'm having difficulty wrapping my mind around the magnitude of the forces involved. Wouldn't sending a climber up to the top ultimate result in that much force being "pulled" on the tether at the bottom? The entire tether would be under extreme stress, although maybe it's insignificant compared to the weight of the tether itself...
