Better with mods adds mechanicle power which is wired through axles to make different blocks work.
For a progression-heavy modpack it would be nice if there was a block to convert this mechanical energy to RF/FE.
The recipe for such an generator does not really matter, but i think it should include soulforged steel which is kindof the highend material in Better with mods.
Also on the other hand creating a motor that creates mechanical energy from an RF/FE source.
The mod could be named "better with electricity".
targetted minecraft version should be 1.12 (maybe 1.10+)
