#Luna

The moon is the industrial hub of the solar system.

#Manufacturing

Most of the manufacturing plants are in or near the craters. During the two-week lunar day, high-quality power from ammonia generators and solar cells fill the electrical transmission grid.

The Lunar processing plants receive raw materials from asteroid mines and mill them using electricity distributed on the grid.

Luna’s micro-gravity is ideal for the manufacture of hardware, tools, and computers to sell to the rest of Sol.

Computer cores and crystals purchased from asteroids fabs generated in zero gravity are annealed to secure shells in the 16% gravity of Luna. Drop something on an asteroid, and it bounces then flies way, on Luna, it bounces but is within reach or at least easy to catch.

The finished products, sold and distributed to all of Sols' systems as linkable, functional building blocks for computers, machines, and bio-interfaces.

#Power

While solar cells can be a significant source of electricity, turbines can provide regular and surge power using Ammonia to drive the reaction.

The power generators take advantage of the extreme temperatures between shade and the sun on the surface to drive the turbines.

Inside the cold darkness of the craters, gaseous Ammonia is condensed and re-pumped to the surface, reheated to spin the generators.

The temperature difference between Lunar day (+125'C) and crater shadows (-170'C) push the gas/liquid transformation.

Glass faced, stainless steel tubes rising above crater walls, capture solar insolation to heat Ammonia to a gaseous state (boiling point -34'C).

Solar cells have a few drawbacks that make them less than ideal for the moon: micrometeorites and dust.

The dust problem, addressed by putting the solar cells in a rack, and shake; shimmy; shake at intervals. Micrometeorites are another problem, the only solutions seem to be at the cell-replace or epoxy level.

Closed-loop ammonia turbines are frequently attached to the solar racks, which increases overall power generation.

Where, oh, where can we find Ammonia on the moon?

Humans are good at generating pee, add a little bit of basic chemistry, and voila, you have all the Ammonia needed, in due time.

At Lunar night, manufacturing plants shut down unless they have nuclear backup generators or have the option to buy/trade electricity with other plants on the sunny side.

Cables crisscross Luna to transfer power during each Luna day.

To make up for the lack of air and dull, dull, dull mountain vistas, Luna has virtually unlimited power to process raw materials.
