A Brief Introduction to Active Support

Active support can be employed to build structures that no known material could support via compressive strength. In high te mega structures, this may be a magnetically shielded structural support with warm temperature super conductors inside it. These objects can be arbitrarily strong and large. Most common shapes would include a circle or ellipse, such as an orbital ring, or a straight line,. They form the foundation of many mega structures. See also atlas pillar, lotstrom loop, orbital ring, shell world and space tower.
