Fallout – Does the Nuka-Cola bottler actually generate nuka cola

INTERIM ANSWER:

I have been working on this problem since I started playing the game, and have come to an odd conclusion: "room types" might include having a full room (3 units) of each type.

I have tracked my Vault's progress on this spreadsheet, and have clearly indicated:

• The 19 types of rooms, and their 3 subtypes
  • e.g., the 3 levels for Diner are: Diner, Restaurant, Cafeteria.
• The number of each rooms I currently have in my vault.
• If 1 or more are present, a 1 gets placed in the "Present" column.
• This column is summed and divided by 57 (3 room types times 19 rooms), and presented as a percentage.

I honestly thought that once I had one of each of the room types, the achievement would unlock. However, this was not the case. At my current loadout, Game Center reports that I am only 40% complete for the achievement.

This has me thinking that not only do we require 1 of each room type, but they all must be of size 3 (many of my level 3 rooms are only size 1). I have now started tracking the sizes of my rooms. My next step is to get a size 3, level 3 of each room type and see how that affects the percentage.

Just got a loading screen tip in the game (the wording may not be exactly the same, but the general meaning should):

Dwellers run on food and water. Rooms run on Power.

This is certainly an official source, although not a very in-depth explanation. From this, one could draw the conclusion that rooms consume power regardless of occupancy, and only dwellers use water, even if this isn't explicitly stated.

To further investigate the details (unless some other source is available), I suppose someone will have to do some science.

Edit: It appears the good folks over at /r/foshelter/ have done quite a bit of science.

Some key points relating to the resource consumption (not absolute facts, but probably close to the truth):

• Food/Water consumption is 21/hour per dweller in the vault (so explorers don't count). This means a L3 full-size Nuka-Cola plant can supply 100 people with food and water.
• Power consumption is a bit more complex, and isn't fully explored yet, but it seems to change with the level of rooms. Still unclear if elevators and other things consume power. For now though, don't build more/larger rooms than you need if power is an issue.

There are a lot of other interesting points made in the thread linked above, so I really recommend checking it out. More detailed information is available here. If they keep the work up, this may be the go-to resource for data on the game.
