I was actually thinking of the space elevator when I wrote that. Hell of a project. Usefull and visibly obvious. Here's an idea: build a pyramid for the base so the elevator comes out the peak ala the Luxor (which used to have that monster spot light projecting out the top but the FAA got pissed). Glad somebody like the question.
Yeah, I like your concept. Of course, to complete the picture, how a bout a dozen of these evenly spaced across the equator. Some of those spots are going to be on water. To the depths!.
But I think the Pyramid builders must have had these already, so I need to think of something else.
