分享未来科技，趋势和投资。科技是第一生产力。设想一下，有一天你走进电梯，按下上升按钮就到了外太空，是不是很酷？这就是太空电梯，它将使向游客开放宇宙的梦想成为现实。
目前，将一个重约2、2千克的东西发射到近地轨道就需耗资约5、3万元人民币，但是太空电梯却可以大大降低成本，让普通人可以在太空中旅行。
太空电梯的载人舱能够在数千万米长的电缆上移动，而电缆则靠地球转动产生的离心力来固定。碳纳米管的出现又朝这一梦想的实现前进了一步。爱德华兹已证明利用纳米技术可以做出能够支撑太空电梯的超强力电缆。
他表示：“建造一个200吨的电梯是个合理的设想而且具有商业价值。一个200吨的太空电梯的大小相当于一架大型的商务飞机。太空电梯的大小完全取决于我们的意愿，不受任何物理层面的限制。”
