Digital manufacturing is also allowing us to do this more effectively. In this case, it's actually creating the theoretical limit of strength for a material. 数字化制造也可以帮助我们进行更有效的回收再利用。这个例子说明了一种材料的理论极限强度。 you cannot get any stronger for the amount of material than this shape. So it's a basic simple block, 你不可能找到比这强度更...
What do we do with them? This process is able not just to recycle them, but to recycle them infinitely. 那我们能做些什么呢？我们不仅应该让水瓶可以回收再利用，而且应该让这个过程无限进行下去。 Why is that interesting? Because when we think about reusing and recycling, 为什么这点很有意思呢？因为像那些能重复利用和回收再利用的东西， metals, glass, things like that, can be recycle...
If there's a building down the block which is being demolished, are there materials there that the new building being built here can use? 如果不远处有一栋楼正在被拆毁，拆下来的这些材料中有没有一些是这边的新建筑物可以使用的？ Can we use that, the ability to understand that all the materials available in that building are still usable?

you can isolate it, and it works very much like carbon fiber. 你可以对它进行分离，它的性质跟碳纤维非常相似。 So, take that from a tree, form it into fibers, and then those fibers can strengthen things, such as airplanes, buildings, cars. 从树木中提取纤维素，接着再制成纤维，然后这些纤维能用来加固东西，例如飞机、建筑物、汽车。 The advantage of this, though, is it's not jus...
