The idea is that the cable would be one long crystal, not sections. You&#x27;d have to continuously extrude the crystal from orbit to the ground or something. You can&#x27;t bolt in new pieces. Whatever the solution will be, cheap is not one of the answers. Just the maintenance on it would be a world-wide effort. And for what? Cheap orbital travel? The real hard part is to find a reason to leave Earth that the oceans and Antarctica don&#x27;t already fulfill. The only one I can think of is orbital foundries or other processes that need 0g. Living space we have a lot of, though cold, Antarctica has air, something Mars and Venus do not.
