Windmill
A windmill is a multi-blocks generator used to empower advanced machines. It is composed of one windmill bearing, one or more radial chassis (which have 4 faces coated with slime) connected to the face of the windmill bearing, on which are fixed some wool. When you have finished to place all blocks, then, right-click with an empty hand on the windmill bearing to start the windmill. If you want to stop it to change the wool setup, redo an empty right-click on the block.
