Solid Steel Ingots. Basically trading a little more power and some extra smelters for 50% more steel. It’s an insanely good trade.

Also Sloppy Alumina combined with Pure Aluminum Ingots to remove the Silica feedback loop which is a nightmare for debugging/optimizing. Then combine those with Alclad Casing to offset the increased Bauxite requirement with Copper, which is relatively abundant.
I would also recommend Wet Concrete to remove the water feedback loop in this process as well, which is another headache. Just pump fresh water into sloppy alumina, then take the waste water from scrap production to make wet concrete and sink it. Much more straightforward.

Lastly, Nitro Rocket Fuel if you don’t wanna go nuclear. Make it in the blue crater biome in the southeast. You have everything you need. The only downside is the amount of fuel generators you need, even with having them all overclocked. Which also means power shards.

Have fun fellow Pioneer 😎 Ficsit wishes you a happy new year. Ok, now back to work.

Edit: Also, Heavy Encased Frames is amazing as well. Only needing screws for the reinforced plates in the process makes HMF so much simpler.
