In Minecraft, the Energetic Infuser is powered by Redstone Flux (RF). RF is a power system introduced in Minecraft 1.5 that is used to power various game devices and machines. In order to power the Energetic Infuser, you will need a source of RF energy. This can be generated by placing a redstone torch or lever next to an active power source, such as a furnace or generator. When the redstone device is activated, it will emit RF energy that can be used to power the Energetic Infuser.
