Power Advantage Mod generally is a helping tool that adds a simple API for adding power systems (such as steam power) to Minecraft. By itself, Power Advantage adds some handy item conveyor machines (which don’t need power) that help you sort items and can transfer items upwards (unlike hoppers) and some machines for collecting, storing, and dispensing water/lava/liquids.
