Compact Early Game Smelter for Eff1 Electric Furnaces and Eff1 transition

This is intended for the eff1 transition on hard worlds with aliens turned up.

So the idea is you max your pollution cloud with the stone furnaces, using as much natural absorption as possible before hitting nests you can’t kill easily.

Then when you unlock eff1 modules you can spread them into your refineries and miners, cutting net pollution in half for the base.

Then you can re double net pollution by doubling miners and adding steel furnaces to those smelting lines.

Then you can eff1 module your chem plants, assembly 2, and your furnaces. When this is done, net pollution has just about been halved again.

Then you can re double net pollution once more by doubling miners and doubling the eff1 electric furnaces.

Once this is done, pollution will be slightly more than what you started - but only because of boilers. So switch to clean power (nuclear preferred) and your eff1 transition will be complete, with 4x production inside a smaller pollution cloud.

This smelting line is the companion I made to follow these calculations, built with the style of the recent smelting lines that have been posted. I’ve actually been making these for a bit now hehe, so I figured I’d share, given the recent interest in re inventing the wheel on early smelting lines.

The odd middle belt strips off coal so that robots don’t have to, and you can add more ore in once you double the length of the line. Notice the circuits on the belts in the electric line, preventing coal from entering the furnace line.

Beacon the electric furnaces. If you don't use beacons, stay with steels on solid fuel. Pollution does not matter for this transition, by the point in game, when this is a thing you can easily increase your safe zone with artillery.
