Hydroponics (supplemental): This is high intensity soilless gardening. This is primarily used to suppliment 'normal', 'meager', or 'emergency' rations on a long term basis. Luxury liners and yachts may use hydroponics to supply predictable quality, quantity, and varriaty of vegitables for the 'excellent' meals. The minimum size listed is the minimum size to produce a continous supply of a limited variaty of vegitables, this will produce vegitables for 2 meals per day per person. This system requires 20kgs of nutrients/person/year as it does not include a complete waste recycle system. This system MUST be used with another source of food.

Hydroponics (full LS):  This is the same as Hydroponics (supplemental) with added waste recycle and upscaled to provide a limited vegitarian diet. This system requires 5kgs of nutrients/person/year to replace losses.

Type V-a: An algae farm which produces a powder that is nutritionally ballanced. This system includes the following components: waste processing plant, atmospheric CO2 removal system, 3 clear tubing systems for single-celled algae production, 1 clear tubing system for "flavor" algae production, filters, chlorophyll removal system, drier, an algae tank, and a storage room. Each of the 3 algae lines can produce sustanence level quanties, and the 3 combined produce sufficient quanties for the average working adult. This system requires 1kg of nutrients/person/year to replace losses.

Type V-b: This is the combination of Type V-a and hydroponics. This system requires 2kgs of nutrients/person/year to replace losses.

Type V-c: This is 2 type V-b systems, one specialized for providing food for animals, with cages for small animals and enlarged algae tank for fish. This system requires 4kgs of nutrients/person/year to replace losses.

Type V-d: This is a Type V-c system, 5 Type V-b systems specialized for providing food for large animals, with room for large animals. This system requires 10kgs of nutrients/person/year to replace losses.

Type V-e: This is 2 type V-b systems and a carniculture plant and nutrient processing equipment. The carniculture plant is vats with cloned musle tissue to reduce waste production (bone, skin, hair, etc.). This system requires 4kgs of nutrients/person/year to replace losses (system sealing and recycling better than earlier models).

With all systems, the larger the system (the more people it supports) the larger the varriaty of foods produced.

Although the systems (except hydroponics) are supossedly closed systems, some components will be lost from the loop (or converted to a non-reusable form, i.e. N2) thus requiring replacement. Also any weight gain by the people supported and any known system losses must be calculated as lost nutrients.  Very well closed systems, such as generation ships, reduce the nutrient losses by half.  At TL 11+, nutrient losses of Types V-a through V-d are reduced by half.  All systems listed include storage space for ten years replacement nutrients. Additional nutrients can be stored at 2000kgs/m³.

Example: A TL 8 generation ship built for 1000 colonists for a 1000 year trip using a Type V-b life support system would require 35.7 Dtons (500m³) for replacement nutrients.  The LS system would require 1428.6 Dtons (20000m³), mass 10000 tons, use 20MW power, and cost 25MCr.
