太空电梯 – 3 层

24-04-2024 15:00

自 19 世纪以来,太空电梯的想法就一直存在;然而,我们仍在继续依赖久经考验的方法进入太空。

火箭进入太空需要使用大量燃料,而且必须携带燃料才能升空,因此,前往月球或火星需要花费数百万美元。有了太空电梯,成本可以降低到每公斤美元。

太空电梯的基本概念是通过配重拉动电缆。由于配重被地球自转向外抛出,而底座则被重力压住,因此电梯可以保持垂直。早期的想法是建造一条从地球升入太空的缆线,但承受如此巨大重量所需的材料并不存在。物理学家提出了一种解决方案–碳纳米管,一种比其他材料更坚固的超级材料。但是,估计有数百万个物体环绕地球运行,它们可能会对电梯造成严重破坏。

可以采取哪些潜在的解决方案或预防措施来应对空间碎片给碳纳米管空间电梯带来的潜在风险?
