There is a pause, and then Corlan steps in to fill it. "A ringworld," he explains, "is a good way to get the most out of a system. You go to a star system, preferably one that's devoid of inigenous life, and you grind everything in that system, apart from its sun, down into raw materials. You strip the planets of their atmospheres, extract all of the ores and minerals, everything. And then you pulverise what's left."
"Then you use it all to build a new world - a ring around the sun, far enough out that the temperature is right for life. You spin it, to make gravity, and provide some rigidity. For Northstar, it's a ring about 275 million kilometres in diameter, with a habitable surface area equal to about three million typical planets. They're still building it, at the moment, but they've started covering the surface with soil and planning to plant vegetation."
"But you can't mine there." Jockram interrupts, "Any more than you could dig a hole and mine for gold under the floor here on Profit Margin."
"No, but the whole surface is usable. How much food could three million agricultaral worlds produce, with no deserts or ice caps to contend with?"
Keryn considers that for a moment, then says, "It would always be daytime. Not that it would bother me. I lived underground, and the lights in public areas were always on."
"No. There is a second ring, inside the first one, which has alternating solid sections and gaps, so it casts shadows to simulate a day and night cycle."
"That... would work."
