Chapter 12: Hi Ho, Hi Ho
The spavator systems were the first step to creating the biomes. These space elevators, often described as the tallest man-made structures on the planet, were critical to the development and construction of the biome ships.
The HUBs were built around the base of each spavator and served several purposes: maintain the spavator; serve as a depot for transport of materials into orbit; house the myriad of fixers that worked to create and maintain the systems; and provide laboratory space for the scientists to develop the tech required for such a massive undertaking.
