So the idea is that there is a HV machine that requires a lot of energy to run, and it suplicates item, the rarer the item, the more energy it needs. And there are a few methods of duplication...
There is the method that uses energy to trnsform one item into another, then there's one where it takes the original item, splits it up, and recreates the item from collected data! Any item would be duplicatable, and you'd need less energy for converting items. The machine also comes with a grinder that produces electricity. Here'sa the cool part, the grinder requires electricity to run. It outputs 10EU, but need 3 to run. So you can use a causation to loop to have the grinder create energy, then just hook up a wire from the export, to the import.
Thank you for reading my ideas.
