About this Mod
Powah! (Rearchitected)
This is the 1.18+ port of Powah!, originally made by owmii for Forge 1.14-1.16. The license is LGPL and owmii has been MIA since 2021, so I decided to pick up the mod. Available on Forge and Fabric in 1.18-1.20. NeoForge-exclusive from 1.21.

Requires Cloth Config and GuideME!
To generate energy, Powah! adds Furnators, Magmators, Solar Panels, Thermo Generators, and of course the Reactor multiblocks!
Powah! also adds the classic Energy Cables and Energy Cells, but also cool and unique mechanics such as the upgradable Ender Network, Player Transmitters, the Energizing crafting system, and a bunch of cool gadgets and items such as the Charged Snowball!
For a good explanation of the mod's content, please have a look at the Manual.
