This is a primitive technology mod, designed to be as close to the vanilla feel as possible. Instead of any kind of electric, magical or biological power, its machines work with mechanical power, produced by turning waterwheels, windmill sails and hand-cranks.
Currently, the mod adds simple vanilla ore doubling via the Grinder, wood doubling via the Sawmill and useful food recipes via the Mill. More information is available on the wiki.
This mod is still in beta. The core concepts will not change, but the recipes and machines well may. Because of this, I welcome any feedback and criticism here or in the issue tracker. Thank you!
