Space Cities Using solar ovens, a few mold forms, an assembly crew, sand-casting, and needed light-weight components from earth (later, we make these ourselves) we mass produce the SpaceCar and build our cities.   SpaceCars are used for storage, cargo, private transportation, and linked together to build restaurants, factories, repair stations, farms, hospitals, schools........
