Create: Solarpunk

A NeoForge mod for Minecraft 1.21.1 that adds solar energy generation, thermal storage, biofuel production, and an optional global warming system to the Create ecosystem.

Requirements

• Minecraft 1.21.1
• NeoForge 21.1.228+
• Create 6.0.4+
• GeckoLib 4.7.2+

Optional: JEI (adds recipe categories for the Solar Heater and Fermentation Vat)

Features

Solar Heat Chain

• Salt - a new material found as underground deposits in desert, badlands, and savanna biomes; the core fuel of the solar heat chain
• Solar Heater - concentrates sunlight to melt salt into molten salt or evaporate water into salt crystals; requires a clear view of the sky
• Solar Power Tower - large multiblock structure (1×1 up to 3×3 footprint, up to 20 blocks tall) that concentrates reflected sunlight to produce molten salt at scale; pair with Solar Mirrors for maximum efficiency
• Solar Mirror - a heliostat that reflects sunlight toward a Solar Power Tower; place directly against the tower's side faces; can be mounted on floors, walls, and ceilings
• Heat Battery - stores thermal energy from molten salt and heats Create boilers

Electricity

• Andesite Solar Panel - generates Create rotational force (SU) from sunlight
• Brass Solar Panel - generates Forge Energy (FE) from sunlight
• Kinetic Battery - stores rotational energy (SU) for later use

Biofuel Chain

• Biomass - crafted from organic matter
• Biomass Pellet - a compacted form of biomass; burns slower in the Gasifier but produces twice the Biochar per piece
• Biomass Gasifier - processes raw biomass or pellets using rotational force; produces Biochar as a byproduct
• Fermentation Vat - multiblock structure (minimum 2×2 footprint, stackable vertically) that converts biomass into liquid biofuel using water; larger footprints process more batches per cycle
• Biofuel Engine - burns biofuel to generate rotational force (SU)
• Biochar - byproduct of the Gasifier; acts as a bonemeal substitute or mixes with water to make Fertilizer
• Fertilizer - liquid made from Biochar and water; used in the Kinetic Sprinkler for forced instant crop growth
• Kinetic Sprinkler - hydrates farmland and accelerates crop growth in a 5×5 area; pipe in water to boost growth or Fertilizer for instant growth every cycle

Geothermal

• Geyser Vent - spawns naturally in desert, badlands, and savanna biomes
• Geyser Cap - harnesses geothermal energy from a Geyser Vent and converts it into rotational force; passive, works day and night in any weather

Global Warming (optional)

An opt-in pollution system, disabled by default and toggled in the config.

• Pollution sources - campfires, furnaces, blast furnaces, smokers, blaze burners, steam engines, biofuel engines, and biomass gasifiers emit smoke and accumulate pollution in nearby chunks
• Block decay - polluted chunks decay progressively: grass withers to Dead Grass, dirt crumbles to Ruined Dirt, then Ash; plants and leaves are cleared; biomes convert to a dead wasteland at high pollution levels
• Biofilter - a brass-tier machine that draws rotational power and scrubs pollution from surrounding chunks, reversing the decay over time; goggles show the current pollution level and filter rate
• All pollution rates, thresholds, decay speeds, and the target dead biome are configurable; see the wiki for full details

Quick Start

1. Find salt underground in arid biomes (desert, badlands, savanna) or craft it
2. Place a Solar Heater with a clear view of the sky
3. Right-click salt into the heater's input slot - it converts to molten salt during daytime
4. Pipe the molten salt into a Heat Battery
5. Place the Heat Battery adjacent to a Create boiler to heat it

For high-volume molten salt production, build a Solar Power Tower and surround its sides with Solar Mirrors.

Solar Power Tower Guide

The tower is a multiblock built by stacking tower blocks and using the Solar Power Tower item to place multiple in a row (like fluid tanks). It operates only in direct sunlight and stops during rain or thunderstorms.

Mirror efficiency follows a triangle curve: efficiency rises linearly from 0 mirrors to the optimal count (100%), then falls back to 0% at twice the optimal. Over-mirroring shuts the tower down.

Minimum size: the tower requires at least a 3×3 footprint to produce anything.
