Priority: H
Make:
Commutator part uses IC2 rotantinal power to rotete shaft.
200 KU > Mechanical Multiblock > 300 RF
this makes the Mechanical Multiblock to best way to produce RF from IC2 Nucleer Reactor.
Becuse:
200 KU > IC2 Kinetic Generator > 50 EU > Galacticraft Cable (Converts EU>RF) > 210 RF

Priority: L
Add a restraining part. When pulling redstone signal slows down the shaft quickly.

Priority: L
Add a steam catcher part to rotete the shaft most efficiant way, ejects IC2 water vapor.

Priority: L
Add another Commutator part to IE's kinetic power. two way.
