Chemfuel is a resource used to craft explosive weapons and ammunition as well as fuel the chemfuel powered generators and pod launchers. If chemfuel catches fire, it will spark briefly before exploding in a fireball.
In spite of the description, it is in no way necessary for neither the construction nor fueling of your ship.
There are several different ways to obtain chemfuel:
- Make chemfuel from wood: Turns 70 wood logs, worth 84 into 35 chemfuel, worth 80.5. Takes 2,000 ticks (33.33 secs) of work, scaling with the General Labor Speed of the crafter.
- Make chemfuel from raw food: Turns 3.5 nutrition worth of food ingredients into 35 chemfuel, worth 80.5. Takes 2,500 ticks (41.67 secs) of work, scaling with the General Labor Speed of the crafter.
Chemfuel is produced when a animal handler milks a tamed, adult boomalope of either gender. The base amount produced is 11 but the amount scales with Animal Gather Yield of the handler. Handlers will milk boomalopes when they are ready, producing chemfuel which will then be left on the ground. Boomalopes can be milked at a base frequence of once every day, however frequence is also affected by the saturation of the animal. Chemfuel production is halved when the animal is hungry, reduced to one third when it is urgently hungry, and completely stopped when the animal is starving.
An infinite chemreactor generates 75 chemfuel every 600,000 ticks (10 in-game days) as long as it is powered by 300W. When it is done producing chemfuel, it will drop a stack of 75 onto an empty adjacent tile.
This process requires no work or input from any pawns.
It can also be purchased from traders.
Mostly used in crafting, however when damaged beyond 1/3rd of its health, it will spark and emit a hissing sound and will explode after between 70 ticks (1.17 secs) and 150 ticks (2.5 secs), dealing 10 Flame damage in a radius around itself. The radius depends on the quantity in the stack, with a single unit of chemfuel covering a 1.1 tile radius, and expanding this radius proportional to the square root of the stack size times 0.037 up to a maximum radius of 3.45 tiles at a full stack of 150. This explosion leaves Chemfuel puddles which will then ignite and burn.
Chemfuel is used to refuel the following:
- Chemfuel generators
- Pod launchers
- Rocketswarm launchers
- Smokepop packs
- Firefoam pop packs
- Jump packs
- Locust armor
- Phoenix armor
It is also an ingredient in the following crafting recipes:
|Foam turret||140||Building - Security|
|Rocketswarm launcher||180||Building - Security|
|High-explosive shell||15||Crafted Resources - Mortar shell|
|Incendiary shell||20||Crafted Resources - Mortar shell|
|Tox shell||10||Crafted Resources - Mortar shell|
|Frag grenades||80||Equipment - Weapons|
|Molotov cocktails||80||Equipment - Weapons|
|Firefoam pop pack||30||Gear - Utility|
|Smokepop pack||40||Gear - Utility|
|Gas mask||20||Gear - Clothing|
|Tox pack||35||Gear - Utility|
|Locust armor||100||Gear - Armor|
|Phoenix armor||40||Gear - Armor|
|Jump pack||100||Gear - Utility|
Due to its volatile nature, it should be stored safely away from flammables and electric circuits, in small compartments which contain small stock so an explosion won't destroy your entire stock. This should not be stored with mortar shells. Be careful, as a pawn may decide to let out their stress by beating up a chemfuel container until it explodes. But with a little creativity, careful placement of chemfuel stockpiles can be used as components in base defense.
Methods of acquiring
An infinite chemreactor is entirely free fuel, taking 0 work or items, only power. One chemreactor can fully load a chemfuel generator, providing both 700 W of extra power and some fuel to spare. However, they are exclusively a quest reward. In addition, the production per day is somewhat slow. These factors inherently limit its viability as a colony's sole source of chemfuel.
Boomalopes can graze on grass for free, and feeding them haygrass or corn still gives more chemfuel per nutrition than a refinery. So long as Animals skill > 4, milking a boomalope itself takes less work than a refinery. Of course, this comes at the usual explosive risk, and boomalopes may not always be available.
Refineries are the most consistently available way of obtaining chemfuel, but require the most work. Even a wood-fueled biofuel refinery and chemfuel generator is both more wood- and work- efficient than a wood-fired generator - don't shy away from using one.
- If you have to grow things yourself, growing corn is much less work (per chemfuel) than growing trees. You can also use insect meat / human meat / hay-created kibble in a refinery with no penalty.
- If your biome has many trees, then harvesting wood can be a viable alternative to converting organics.
- Beta 19 - Chemfuel can no longer be acquired by deep drilling.
