I don't know my version or loader
This mod adds a single block, the Alternator, which converts kinetic energy (as RPMs) from Create to Forge Energy in a quadratic curve.
If you're familiar with the alternator from Create Additions (this borrows some code from it), it's like that, but the math that determines output and the configuration options are quite different. This alternator does not require 32 RPMs (it works at all speeds). This alternator also has a different model and a shaft running all the way through it (although it doesn't currently render due to a bug).
You can use this Desmos graphing calculator to view the energy generation curve. If you want to configure it, the 8 is "generator_divisor", and the 1 is "generator_multiplier" from the config file.
