Wind Turbine

Summary
The Wind Turbine makes EU/FE from the wind — no fuel, no sun, just altitude and weather. Build it high and it pays off; build it on the ground and it does almost nothing. It rewards players who climb a tower and don't mind a storm. To run, it needs three things: a Wooden Rotor in its slot, open sky above, and clear space around the blades. The worse the weather, the more power it makes.
Mini-example: one turbine at the top of a tall tower (around y=128) → 4 EU/FE/t on a clear day, 8 EU/FE/t in a thunderstorm. A row of them up high is a free, weather-powered backbone for your base.
Energy
The turbine only produces power — it never takes any in. It holds up to 4000 EU/FE inside and sends it out on an LV line.
| What | Value |
|---|---|
| Internal buffer | 4000 EU/FE |
| Output | up to 32 EU/FE/t (LV) |
| Realistic output | 0–8 EU/FE/t (altitude × weather) |
Energy comes out only from the back face. Connect your cable to the turbine's back wall — the other sides output nothing.
Generation
The higher above sea level and the worse the weather, the more power. The base grows with altitude, and the weather multiplies it.
| Altitude / weather | Output |
|---|---|
| At sea level | 0 (useless on the ground) |
| +1 EU/FE/t per ~16 blocks above sea level | up to 4 EU/FE/t near y=128 |
| …in rain | ×1.5 |
| …in a thunderstorm | ×2 |
| Overall cap | 8 EU/FE/t |
So a turbine near y=128 makes 4 EU/FE/t clear, 6 EU/FE/t in rain, 8 EU/FE/t in a storm — but the moment it's roofed or the blades are blocked, it stops dead. If something's wrong, the screen says so in plain words: "no rotor", "roofed", "blocked", "interference" or "calm". When it's actually generating, the gear indicator lights up.
Blade clearance
The blades spin in the block in front of the turbine and need room around them. Keep these clear: the block in front, one block to each side, and the three blocks directly below (a little pit). If anything solid is there, the turbine shows "blocked" and stops. "Clear" means air, grass, flowers, saplings or snow — anything you could place a block into. Stone, glass, leaves, fences, slabs or the turbine's own support pillar all count as blocked. You don't need to check the air above the blades — a roof is caught separately by the open-sky check.
Placing several turbines
Simple spacing rules so the blades don't collide: Same direction, side by side: leave 1 block of air between them, or both stop. Back to back: can sit right next to each other. Face to face: need at least 2 blocks between them. When two turbines interfere, both stop, no exceptions. A neighbour with no rotor causes no trouble — but the moment you put a rotor in it, a running turbine next door stops too.
Inventory
Two slots:
| Slot | Takes | Count |
|---|---|---|
| Rotor | Wooden Rotor (required — no rotor, no generation) | 1 |
| Chip | evolution chip (solar/lunar) — starts the evolution | 1 |
Interface
The screen shows the energy bar (with exact EU/FE on hover), current output, the working mode, the rotor slot in the centre, the chip slot on the right, evolution progress at the bottom and a status indicator on top.
Block Properties
An ordinary solid block, placed facing the player. Any pickaxe breaks it, and it keeps its charge when broken.
| What | Value |
|---|---|
| Tool | pickaxe |
| Keeps charge on break | yes |
Sound
While the rotor spins, the wind mill softly rustles its sails in the wind — the loop (pattern C, humVolume 0.22, fixed 12-block range). It falls silent in calm weather, under a roof, on a neighbouring rotor's interference, or with no rotor installed.
Recipes
Two crafts at a workbench: Wind Turbine — copper ingots in the corners, planks top and bottom, copper cable on the sides, a wooden gear in the centre. Wooden Rotor (required to run) — planks in the corners, iron ingots top and bottom, copper cable on the sides, a wooden gear in the centre.
Progression
The basic turbine is the neutral tier-1 form. Drop in an evolution chip (the same one solar panels use) and let it run under open sky with a rotor in, and it turns into a stronger version, keeping its stored energy: Solar Evolution Chip → Sky branch: stronger at altitude → Sky Mill. Lunar Evolution Chip → Tempest branch: stronger in bad weather → Tempest Mill. Expect roughly a day and a half (~28 real minutes). Evolution is weather-independent: the chip keeps accruing progress in any weather, as long as there's open sky above the mill, the blades are clear and the rotor is installed — so, unlike the solar panel, the wind mill evolves at night and in the rain alike.
| Tier | Sky branch (altitude) | Tempest branch (storm) |
|---|---|---|
| T1 | Wind Turbine (neutral) | Wind Turbine (neutral) |
| T2 | Sky Mill | Tempest Mill |
