Windmill (Immersive Engineering)

The Windmill is a block added by Immersive Engineering. It is used to generate Redstone Flux (RF) when connected to a Kinetic Dynamo.

Building another Windmill of any type in close proximity (up to 7 blocks in front of it) will reduce its speed.

Windmills (0.12-76 and earlier)
The amount of energy produced depends on the altitude the Windmill is placed and if it is raining or not.

The power output can be improved by crafting an Improved Windmill.

Windmills (0.12-77 and later)
The amount of energy produced no longer depends on the altitude of the Windmill but rain and thunder still increase power production.

The power output can be improved by right clicking the hub with Windmill Sail. You need 8 to improve it to maximum power.
