Sky Mill
alaindustrial:high_altitude_wind_mill
Summary
The Sky Mill is the second tier of the sky branch (T2), an evolution of the basic Wind Turbine. It produces EU/FE from the wind with open sky above, but its base grows with altitude twice as fast (its ridge takes 8 blocks per step instead of 16) and caps at 12 EU/FE/tick. Weather affects it less than the other turbines (rain ×1.25, thunder ×1.5) — this is the steady-income turbine, not the peaky one. It is obtained only through evolution of the basic turbine with a Solar Evolution Chip; it has no crafting recipe.
Energy
The turbine only produces power and never accepts incoming energy. An 8000 EU/FE buffer, LV-tier output. Energy is emitted from the back face only — same as T1, so the cable on the back wall keeps working after evolution. The other 5 faces are inert.
| Field | Value |
|---|---|
| Role | producer with buffer |
| Buffer (EU/FE) | 8000 |
| Max input | n/a (does not accept energy) |
| Max output (EU/FE/tick) | 32 (LV) |
| EU/FE/tick | 0–12 (base 0–8 on the altitude curve, peaking under the clouds × weak weather multiplier, capped at 12) |
Generation
As with T1, but doubled payoff from altitude: the wind curve's ridge is reached at 8 blocks per step above sea level (instead of 16), up to 8 EU/FE/tick, and weather multiplies it only weakly: rain ×1.25, thunder ×1.5, capped at 12 EU/FE/tick. At y ≈ 128 the Sky Mill outputs 4 EU/FE/tick — twice what the basic mill makes at the same height, but only half of its own full base; the full 8 EU/FE/tick comes only in the y 188–192 band, under a clear sky — more than any other turbine in fair weather.
| Field | Value |
|---|---|
| Source | wind: altitude above sea level + open sky + weather |
| Working condition | rotor installed AND open sky above the block AND blade area is clear AND buffer not full |
| Dimensions | minecraft:overworld |
| EU/FE/tick (base) | on the wind curve; maximum 8 at y 188–192, 0 above y=248 |
| Modifiers | weather: clear ×1, rain ×1.25, thunder ×1.5; result capped at 12 EU/FE/tick |
Altitude, sky and weather are recalculated roughly once every two seconds; between recalculations the rate stays the same.
Blade clearance and rotor interference are exactly the same as on T1: the rotor needs a clear 2×2 square in front of the turbine, and overlapping blades with a neighbouring turbine stops both. Full rules and the diagram are in the T1 spec.
Interface
Type: container — energy bar (tooltip on hover), the central rotor slot and status indicator in the same positions as the basic turbine. While the turbine runs, the status row shows the current output in EU/FE/tick; while it is stopped, the reason. No chip slot and no evolution progress (T2 is a leaf — it doesn't evolve further).

Recipes
The Sky Mill isn't craftable. The only way to get it is to grow it from a basic turbine: insert a Solar Evolution Chip and let it work under open sky with a rotor installed. The stored energy carries over on evolution.
Crafting: none. The block is not available from a crafting table. Evolution (the only way to obtain it): a basic Wind Turbine + rotor installed + a sun alignment chip + accumulated open-sky time → turns into the Sky Mill, keeping the energy it had stored.
