[Farm Removed] A 2 billion unit/day (and growing) S-class Indium farm that refills every 2-3 hours. Come help yourself, more money than I will ever need. Leave a message at the base of the power distribution tower! Enjoy.
Notes
Base is on same planet as portal. Base coords: +27.37, -75.77. System is an affluent blue star, so there's opportunity to get any S class at the space station or trading post. Plenty of protection from nasty storms at base.
