I don't think you are asking the origins of the idea.

As that has already been covered. People were attempting theft on this.

 

Rather how it was built. More or less, that is it Mr Musk.

 

It's not something too complicated. But it relies on first principles.

 

Structural stability, when height increases. Which is the basics

of any architecture. I merely had thought of machines to drop

the cubes, and stabilize it however way possible.

 

 

 

 

And if it works, (there is no reason why it wouldn't)

 

 

then the world has access to materials in outer space,

by sending materials from Earth as tools (in volume).

 

So simple as it is, i've done quite a good work on this.
