Sorry but this is taking a while. Three pages on my post now and I haven't gone back to fiddle with quality :)

As for the Energon issue, which admittedly, I haven't fully read over so excuse me if I'm reiterating the words of someone else... If you're going via the old cartoon, various natural resources can be made into energon. It never made much sense to me how they squished the oil into energon but the principle could be somewhat similar. Maybe they have a means of making Energon or perhaps the Energon exists on several worlds in the Star Wars universe and nobody's realized their value.
