Not sure if this is a bug or a change but since i didnt see it in the changelog im posting it just in case

The alternator uses 1/16th SU that it should normally use. Even when deleting the config file , the alternator produces 360 FE with 1.024 SU at max speed , while the electric motor produces 16.384 SU with 480 FE at max speed.

I found the bug in the code.

The Alternator is using SU intended for Mechanical Mixer, here:

@Override protected Block getStressConfigKey() { return AllBlocks.MECHANICAL_MIXER.get(); }

Changing the config of the Mechanical Mixer is also affecting the Alternator.

We also face this exploit.

When hooking uo to a motor you can multiply the energy created *16 and build a perpetuum mobile.
