The Great Heep's operation on the planet Biitu included a massive space-based fuel-ore processing plant. This facility was designed for the extraction of fuel-ore and was an enormous manufacturing complex. This elaborate structure comprised a complex network of interconnected elements, including pipelines, moving conveyor systems, large rotating gears, lifting cranes, high-temperature furnaces, and a variety of other mechanical components. At the very top of the plant was a moisture eater, a large funnel-shaped device that drew in nearby clouds and moisture, creating a vortex that resembled a tornado.
