Steam Turbine

Added the Steam Turbine multiblock. Build a 7x7 shell of Turbine Casing (or Turbine Casing Glass) around a column of Turbine Rotors, then fill each interior layer with Turbine Blades in a plus pattern - two blades per arm, four arms. Pipe steam in from any side face and rotational power exits from the top of the rotor column.

Blade type determines efficiency: Andesite Blades are cheaper but waste more steam, Brass Blades squeeze the most power out of every bucket. Mixing types is fine - efficiency scales smoothly. Taller turbines consume more steam and produce more SU, with condensate water draining from the bottom.

Steam

Added Steam as a new fluid. It is the fuel source for the Steam Turbine and can be bucketed and piped like any other fluid.

Solar Power Tower Steam Mode

The Solar Power Tower can now produce Steam in addition to Molten Salt. Right-click the tower with a Wrench to toggle between the two modes. Switching clears the stored fluid, so you cannot accumulate both at once. Steam can be piped directly to a Steam Turbine, making the tower a self-contained solar-to-power chain without needing a Heat Battery and boiler.

Turbine Casing Crafting

Turbine Casing is crafted by right-clicking a Block of Industrial Iron with a Zinc Ingot, or by running it through a Deployer holding zinc. Right-click a Turbine Casing with Glass to get the glass variant. Both work in-world and in a Deployer contraption.

Solar Mirror

The Solar Mirror has a new model and texture, replacing the old glass-and-stone design with a single dedicated texture.

Bug Fixes

• Fixed milling crops, leaves, and saplings in the Millstone producing nothing. The recipes were missing a processing time, so the mill would spin forever without completing.

Balance

• Solar Power Tower (Salt Mode): Molten Salt output has been substantially reduced. The previous rate was tuned for steam production and left the salt chain with far more capacity than a Heat Battery setup could ever use. A max-size tower now produces enough to run 9 Heat Batteries continuously.
• Fermentation Vat: Now requires a minimum height of 4 blocks to operate in addition to the existing 2x2 footprint requirement. This is configurable.
