One issue with modules is, that it's not clearly spelled out.

Going by basic costs, neither modules nor drop tanks are gravitationally tiled, so that aspect is likely installed exterior to the module, and has to be powered there.

On the other hand, life support, if indicated as an aspect of module, would need to be powered on the module.
 
I think I found a bug. I am running a 400T TL13 ship with fusion power plants cranking out 500 Power. No jump drive

Standard TL12 would make for 33.33 tons, and a fuel usage rate of 0.1 tons per ton of power plant =3.33 per week
TL13 so I get to add "reduced size" which reduces the power plants to 30 tons. Reduced size fuel usage is 1.5 times standard, though, so it should become ~4.5 tons per week.

For TL12 I choose 12 weeks of operations, which should be ~40 Tons, it is saying 12.
For TL13 I am also choosing to have 12 weeks of fuel, so it should require ~54 Tons, but the spreadsheet is saying 9.

It is possible I am doing something wrong, but this is what I am getting. [I did edit to fix one math error already]

Ok, I forget where I saw that "Reduced Size" power plants used more fuel. And I read "per month" as "per weeks". I am a bad person.

In the official designs, this is not made clear. Also, some designs that require life support do not have any power plants, implying that they can pull power from the host ship so I would assume it can go either way, add your own power plant if it's a large draw or use the Cutter/host without installing a local power plant if it's not too large.

Arkathan, In the spreadsheet, when designing modules, it shows errors if a drive or power plant is installed with a note saying they are not allowed on modules. But both exist on official designs. Also, not having a computer sometimes throws an error on the summary sheet, I haven't figured out why yet. I'm throwing on a couple of sheets to show what's happening. This happens if making a space worthy design or not.

If you make all of the ship's decking out of Induction Plates for 5,120Cr/ton of ship (minus fuel storage) this would work.

Edit - Robot Handbook page 120
So you'd put the chargers in their feet? Clever. Still, plates on the walls in engineering would be fine in almost all cases.
 
Behind bars, under seats for control stations, the med bay...
If I forget (and I am writing this to remind myself) remind me to add the those plates to the robot crew section.
 
Ok, new item! For the modules, there is a TL6 power module mentioned in the TL12 Power Module so I made one. You get an error on the fuel page because Standard Fuel Tanks are TL7. I don't know why fissionables need tons of fuel per week but can we get a basic or primitive prototype tank so we don't have to error out?

If you use the small craft toggle, it uses a lot less than a ton a week. Still, I don't know why the minimum fuel is hard coded either. Even antimatter power somehow needs hydrogen fuel. I made this for a 30 ton test using your TL6 fission power plant..

Though 4 weeks of antimatter fuel was miniscule.

yes, I have the Small Craft Fuel Rule set to yes by default. That's not the issue. The issue is you see that little 7 in the TL column? If you are building a TL6 module using Fission it throws an error. Not a big deal because I can ignore the error. but it's there. My comment about the fuel size was just my wondering why fissionable are so huge but it had no relevance to my actual question. :)

Yes, but I simply must focus on the smallest detail rather than the big picture. ;)
