When I was building the "soup" that fueled the creation of
Rome's Revolution, I put a lot of thought into alternative technologies to make the Vuduri our equals or superior, technologically yet different.
One of the things I researched is called Plant Transmutation. It has been proposed that certain plants can "manufacture" elements they need by way of Low Energy Nuclear Reactions which is similar to cold fusion. Some people have claimed that plants could form proteins which would bring certain molecules within sufficient proximity that they would spontaneously fuse to form higher order elements.
To my knowledge, no one has produced a widely accepted experiment documenting such abilities. Even the anecdotal evidence seemed so weak, I decided to abandon it. Instead, I just gave the Vuduri a thing called the molecular sequencer which could build anything essentially one atom at a time. I didn't bother worrying about whether they had the correct elements in the first place. It was whiz-bang enough to just let it go.
I imbued MINIMCOM the ability to phase-delay transport of atoms and transmute them and that is probably enough. He's already way too proud of himself.
