1 more thought. Actually 2.
1st off. For anyone who has read any Larry Niven with the Ringworlds you would know that SE4 ringworlds are not realsitic at all. They should be built about 1 AU out
The Astronomical Unit is the average distance between the Sun and Earth. Its value is 149,597,870 km (about 93 million miles). and should be a ring. IF you do the math you will get at 1 per sq mile (earth is at 104) and 3/4 water with ring 200 miles wide 29,203,000,000. A sphere world will be 27,146,000,000,000,000 with the same 3/4 and 1 sq/mile. 27 QUADRILLION PEOPLE. RANGE CHECK ERROR. But think of the production bonuses (once you programed it that high of course). Something should be done to fix the 32/64 billion problem.
2nd thing. Damn, took so long to do the first i forgot the second ill get back to that.
