I played a lot of Factorio recently.
I wasn't able to get a good video, so here's a bunch of pictures instead. Starting with the map:
First up, the solar power plant:
The solar plant powers the whole factory. The panels on the left generate power during the day. Accumulators, on the right, store excess power so we can keep running at night.
The older coal power plant is still hooked up as a backup source:
Coal and water are fed in at the bottom. Boilers use coal to boil the water, and the resulting steam is used to drive the steam engines.
Most of the time it's just inactive, though.
Iron, copper, and coal are mined from the ground and delivered to the factory via trains. We'll look at coal as an example.
The coal mine:
The coal train is loaded:
Here's the main train station:
This is where iron, copper, and coal are delivered. The research facility is on the left. Production is on the right.
In theory, we would need stone to be delivered here as well. The stone mine is close enough, though, that I never needed a train for it.
Before we look at production and research, we'll have a look at the oil refinery as well:
Crude oil is delivered via train on the left. Crude oil is processed into heavy oil, light oil, and petroleum gas, which are used elsewhere in the factory.
There's a lot of careful handling here to make sure we never have any shortages. Excess heavy oil is cracked into light oil, and excess light oil is cracked into petroleum gas. If heavy oil is low, then crude oil is routed through a different set of oil refineries that produce more of it. I found that this setup works quite well.
Here's a small part of the production facility:
The basic idea here is to have isolated factories that take in raw materials, from the bottom, and send products out the top. Here's where assembling machines are produced, for example:
All of the processing needed to make assembling machines happens here. Iron and copper are smelted in furnaces. Copper plates are used to make copper wires, which are used to make circuit boards, which are used to make the first tier of assembling machines... and so on.
These isolated factories are composable, as well. The above factory, for example, contains four copies of a smaller factory that produces circuit boards.
This approach worked pretty well for me, but has a large footprint and can be pretty wasteful. There's a lot of open ground that we're not utilizing, and at any given moment, ~90% of the factory is inactive. On the plus side, being able to break complicated pipelines down into smaller pieces helped me keep things simple.
A couple pictures of the routing for raw materials:
And here's the factory for one of the more complicated products, Speed Module 3:
Finally, here's the robo warehouse:
All finished products are exported to the robo warehouse. Logisitic robots pick up delivered products from provider chests on the outskirts, and store them in long-term storage chests that surround the roboport.
The robo warehouse is connected to production via circuit network, which is used to enable/disable production as needed. Assembling machines, for example, are only produced when we have <50 in storage.
Let's skip over for a look at the research facility:
Same idea here. Isolated factories produce different types of research from raw materials.
The main difference is that finished products are exported to a long, circular belt for delivery to the research labs:
Finally, here's where I made the rocket:
Launching a rocket into space is the end-game goal, and pretty hard to achieve. Researching the rocket silo took me 4 hours. The rocket silo itself was easy enough to build, but it took me another 5 hours to make the rocket once I had the machinery in place. That's a lot of machinery too.
There is more you can do beyond launching the rocket - space research gives you access to endless research - but I'm taking a break for now.
Had a lot of fun though.- ava
