If this posts correctly, you can see the three launchers there. This is a coolant factory farm with 18 Factories. I pull p1 materials from the extractor planets and fill up the POCO with the respective p1 mats (water and electrolytes) to the bottom launchers there on the ice planet. The top one receives all the outputs. If I had used only one launcher, I would have to submit a expedited transfer twice for every time I had to refill the launchers. Once from the silo that would receive the Coolant and after that was exported, the other p1 to another silo to maximize how long I can leave it and go. Or just limit myself to a single launcher from which all the factories pull from, forcing me to return here in half a day at best. These layouts are catered to MY playstyle and schedule. They are intended to be the least troublesome so that I minimize how often I have to do pickups/transfers and deliveries. Using three helps me land on the planet and finish the pull and refill and be done as quickly as I land and align to my next planet or station. It’s quick enough to do everything while in warp in a moderately sized system, 40au being the farthest warp, 5 of them being within 15au of each other. Aside from the regular push and pull every day and a half (sometimes I don’t even have to move the ship, but simply sign on or do this all at the undock). Timed, it takes only 10 minutes per character. I migrate the finished product every week and a half, when it can fill an entire epithal’s PI specialized hold full of p3 and p4. That’s more than a generous extra income for relatively low maintenance setups.
