Wow this is a great addon! Totally installing this after the rest of my addons get updated. Massive EU storage in chests? Sign me up! Makes things a bit more limited with flying in survival since I have to use a different mod to provide flying in smp with no cost, I would prefer to do it with a high EU cost and be able to justify it instead of OP FLYING HAX. I do like the idea of a matching suit though, it would look nicer that way. I do support the use of uranium somehow in this since I have been accumulating it without the use of reactors.
*Random Idea* A fast, EU powered speed boat, with multiple seats would be nice. What could be better than a few friends, some fishing poles, and a six pack of beer right? Or maybe for raiding missions with a team on underwater bases as a more practical application. Even better if it has laser guns, but then we are leaking on to Industrium Conflict territory. Maybe press a customizable button to access the boat's inventory and charge it with items. Not sure how the boat would be crafted,more than likely with many stages to make the cost keep it from being OP, but would provably include a grav engine or two and multiple advanced lappacks. It wouldn't fly but it would be supporting enough weight to provide forward momentum.
If mounted guns were implemented id imagine it as being crafted from a mining laser with some power items and maybe other advanced materials. Then it would either be crafted with the boat for simplicity or have a slot in the boat's inventory for mounting. Then the laser would drain from the boat's main storage for each shot. The boat might also have a small inventory for storing extra power packs or other items.
Also maybe have a block that can be placed to automatically charge it when it is within a few blocks. That way you can feed your power generation to a harbor and have a boat that will charge itself without having to worry about feeding charge items in to it, but it would have to be well hidden on smp. Just some food for thought since the idea of expanding the mod beyond armor in to super tech inspired me. I know the boat would be a monster to code, yet alone design but how about a nice challenge?
EDIT: Broke up the text wall, this is what happens when I get two hours of sleep and try to post somewhere.
