Guidice got instructions from O'Neill on how to depict the interiors of colonies. “He wanted it to be very rural farmland kind of thing. Not really high density. But most likely it would not be like that.”
How did O'Neill and other space colony proponents think to justify the immense cost of building these colonies?
“It became a stepping stone—people who lived there would be free of the earth’s gravity and would be free to travel and do other things, like asteroid mining. They would go out on a large mission and capture an asteroid and mine all the valuable ores out of it. [They'd] then shoot them through a linear accelerator that would decay the orbit and would bring this mass of material closer and closer to the Sun until it got to the orbit of the Earth. They would then unload, reverse the process to stabilize the orbit, and take all the material, using it to built whatever was required, or returning it to the Earth as an economic commodity.”
