Opinions on the World of Subterfuge?

I haven't seen it mentioned anywhere so I'd like to bring up some things to stimulate general discussion. I'd like to see peoples opinions on how things work in the world of Subterfuge. To start off, I'll list some questions and ideas that have occurred to me as I've been playing. Please feel free to speak your opinions or voice questions you have about how the world of Subterfuge actually functions.
How fast do the subs actually travel?
The closest outposts are normally about 12 hours away. Are we sending our drillers hundreds of kilometres, or thousands?
Why does the map loop?
Is the game taking place around an entire planet? If thats the case, why isn't there any land.
What even are drillers?
Seriously! Why do they need power? How does it get to them, extension cords?
How do the generators make power?
Are they using thermal vents? Nuclear fusion?
Why do I want Neptunium anyway?
Can I do something with it? Is it valuable? Who would I sell it too?
I hope people are able to debate their opinions on this. I look forward to reading through everything. Hopefully I left some other questions for people to ask.
