Carbon Nanotubes and Mini Fusion Power Guide

If your factories are starting to choke on Carbon Nanotubes or your grid keeps falling behind expansion, you need a plan that does more than just “make more stuff.” The fix is to choose the right Carbon Nanotubes route early, keep the crystal line from turning into a logistics mess, and then use Mini Fusion Power Station setups as a compact power core wherever your grid needs to stay alive. Do that in the right order, and you’ll solve both a materials bottleneck and a power bottleneck before they snowball.

Decide which Carbon Nanotubes route you should build first

Start by asking one question: do you have access to Spiniform stalagmite crystals yet? If you do, build around them first. That route is the cleanest way to get Carbon Nanotubes online because it bypasses the graphene bottleneck entirely. The normal route works, but it depends on graphene, which in turn depends on how well you are handling crude oil processing. If oil is still tight, pushing Carbon Nanotubes through graphene can create waste and stall other production lines.

Use the oil-based recipe only when you already have a stable graphene supply and want to lean on infrastructure you’ve already built. Otherwise, go hunting for Spiniform stalagmite crystals on ocean planets and plan your expansion around them. These crystals are often submerged, so do not forget to place foundations under the veins before you mine them. That small setup step matters, because you cannot scale what you cannot actually reach.

Here is the quick reference for the core pieces of this subsystem:

Set up Carbon Nanotubes so they do not become a logistics headache

Do not treat Carbon Nanotubes like a niche intermediate. They are a key ingredient for Frame material, Particle broadband, and Proliferator Mk.III, so demand can spike across multiple late-game chains at once. That means your supply needs to be stable before you start scaling the rest of the factory around them.

If you have Spiniform stalagmite crystals, convert them as soon as practical. They are only used for Carbon Nanotubes, so there is no reason to leave them sitting in storage unless you have a very short-term reason to do so. Turning them into Carbon Nanotubes reduces logistic demand to one-third and improves storage efficiency: six stacks of crystals become one stack of Carbon Nanotubes. That is a huge win for hauling, buffer space, and your own inventory management.

This matters even more once the rest of the factory starts pulling on the same materials. If you let raw crystals pile up, you are carrying around bulky stock that could already be in its finished form. Convert first, distribute later.

Solve the bottleneck before you try to scale Carbon Nanotubes hard

Do not build your long-term plan around natural Carbon Nanotube harvesting. You can get small amounts from certain plants, especially larger trees on Mariterra, Prairiea, Crimsonis, and Tropicana, but that is a stopgap only. Even clearing an entire planet usually gives you enough for just one or two items. That is useful when you are stranded, but it is nowhere near enough for real production.

When you want scale, build around a mineable Spiniform source or a mature graphene line. If you are still relying on the early oil route, keep a close eye on balance: crude oil processing can become wasteful fast if you overcommit before the rest of the chain is ready. And remember that the crystal route is not as cheap as the normal route, since the Spiniform stalagmite crystal requirement increased from 2 to 6 in version 0.9.26.12891, so you should size your mining and Chemical Plant count around that higher input cost.

The practical takeaway is simple: use plant drops only as emergency scaffolding, then move to a real supply line as soon as you can. The earlier you do that, the less time you spend fighting shortages later.

Build a Mini Fusion Power Station as your compact late-game power core

Once your production starts stretching your grid, switch to Mini Fusion Power Station for dense, reliable power. It burns Deuteron Fuel Rods, and at full load it consumes one rod every 40 seconds while producing about 15 MW. It takes the same basic footprint as the Thermal Power Plant, while giving much higher output. If you need strong power in a small space, this is one of the best options you have.

The other reason to like it is that it responds to demand. When your grid load is low, it burns less fuel. That makes it much more forgiving than a setup that must run full time whether you need it or not. Use that behavior to your advantage: place Mini Fusion Power Station where your power demand swings, and let it throttle itself instead of wasting fuel.

This is especially valuable for late-game industrial zones where you want compact coverage without covering half the planet in generators. It also works anywhere, because it does not depend on wind or solar conditions.

Feed fusion power without letting the fuel chain stall your expansion

Do not treat fusion power as a simple generator upgrade. Treat it as a logistics project. The real bottleneck is the Deuteron Fuel Rod chain, not the building itself. That chain needs deuterium, iron, copper, titanium, stone, crude oil, and water, and it also depends on super-magnetic rings and titanium alloy. That is a lot of moving parts.

Titanium is the first thing to plan around. Your starting planet does not contain titanium veins, so if you want Mini Fusion Power Station at scale, you need interstellar import lines or expansion to a world that actually has it. Do not wait until the grid is already strained to solve that. Build the rod line early enough that the fuel system is ready before the power crisis hits.

If you want a practical benchmark, remember that even hydrogen from X-ray Cracking can carry a factory quite a long way when the fuel line is built early. The point is not to use fusion as a last-second miracle. The point is to make sure the fuel chain is already alive when the rest of the factory starts demanding it.

Use fusion power as a temporary bootstrap tool, then move it where it matters most

Keep at least one portable fusion setup ready for expansion work. Carry a Mini Fusion Power Station and Deuteron Fuel Rods with you so you can quickly power a newly placed Interstellar Logistics Station, recharge Wireless Power Towers, or refill your mech when a new world is still dark and undeveloped. That lets you bootstrap an outpost immediately instead of waiting for the local grid to mature.

Once that temporary setup has done its job, pick it up and move it somewhere else. Mini Fusion Power Station is compact, weather-independent, and useful anywhere, so it is worth treating as a movable asset rather than a fixed monument. If you connect power facilities directly with a Sorter, you can also transfer fuel automatically between them, which makes small fusion clusters much easier to resupply without babysitting.

Use this pattern: bootstrap new territory, stabilize the local logistics, then relocate the fusion core to the next problem area. That keeps your best power tools active where they matter most and prevents them from sitting idle in a place that no longer needs them.
