The fuel cell is essentially
- several large chest filled with redstone dust
- hoppers underneath it to transfer it
- along certain hopperlines there are redstone comparators that detect flowing materials
- the output of the comparators power the circuits inside the ship (interior light, the engines, docking bays, etc.)
- the hopperlines are controlled by several levers, 4 in front of it and 2 (of the engines) in the control room

Thus creating the effect of a powered ship that runs on a fuel cell. Of course when the fuel is up, it's powerless but has emergency lightning system & the imported ones still work (doors and such)

Hope this clears some thing up

Glad you like it :-)

Thanks for the support, there are other amazing entries as well. So time will tell.

Redstone trouble? That was the fun part of this build to make. Thinking of what kind of stuff I wanted into it, make the general frame & start building/creating the most critical parts.

Ah, yes presentation. I spent these days way more time on it, to properly flesh out the stuff I cramped into it. Atlhough I am still learning blender (chunky has some Java-library issues on my PC). At least it seems to pay off. Still wanting to get to the point of making those fancy clean looking 360rotating *gif.


Thanks for the comment :-)
