Suggestion: The Electolyser animation needs more framez.
The one frame animation currently is a little sad!

Good work overall on the reskin.

I'm willing to explore using the accumulator electric arcing as an animation for the electrolyser. No guarantees I'd implement it, however. Depends how easy it is to do and how good it looks.

Any other sort of animation is beyond my abilities, I don't have the 3D model.

Thanks. I wonder if the recent lightweight particles like "spark-particle" might work?

Other (possibly) easy options are LEDs and/or steam?

From a code implementation standpoint ripping the accumulator may be easiest, lel. All the ways I'm familiar with making smoke/particles for assembly-machine prototypes involves the energy source.
