建造这样一个设备将意味着,会架设一条在地球同步轨道卫星下方,地球赤道上方的电缆,同时还可以在太空中有效利用这个对重平衡电缆。
The cable from Earth to the satellite would not be a classic lift rope because it would not,itself, move.
从地球连接到卫星的电缆将不会成为一个经典的电梯电缆,因为它本身将不再移动。
But it would perform a similar function of support as robotic cars crawled up and down it,ferrying people and equipment to and from the satellitewhence they could depart into thecosmos.
