We call them "generation ships," but what they are really small cities containing every aspect of a city, from education and emergency services to industry and manufacturing. The only difference is *no raw material," meaning no logging, mining, original farming, etc. Basically not one atom of new resource throughout the trip. It's all recycled. | |
