How to Use This Calculator
  1. Enter the number of crew members to support.
  2. Input daily O2 consumption and CO2 production rates per person.
  3. Set the plant species and growing area dedicated to bioregenerative food and air recycling.
  4. Review the percentage of oxygen, water, and food needs met by the bioregenerative system.
  5. Supplement with stored consumables for the gap between bioregenerative output and crew requirements.

What each input means

Crew size
Number of crew to feed.
Growing area (m²)
Total crop growing area.
Light hours/day
Hours of grow light per day.
Primary crop (1-3)
1 = Lettuce (fast, low cal), 2 = Wheat (staple), 3 = Soybean (protein).

What each result means

Daily food produced (kg)
Edible food harvested per day.
Calories per person/day
Daily caloric contribution per crew member.
Food self-sufficiency (%)
Percentage of caloric needs met.
O2 produced (kg/day)
Oxygen generated by photosynthesis.
Water needed (L/day)
Daily water consumption by plants.
Area for 100% food (m²)
Growing area needed for full food self-sufficiency.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Crew size = 6, Growing area (m²) = 50, Light hours/day = 16, Primary crop (1-3) = 2 = 4 input(s) provided
  2. Calculate Daily food produced
    Daily food produced
    1 = 1
  3. Calculate Calories per person/day
    Calories per person/day
    567 = 567
  4. Calculate Food self-sufficiency
    Food self-sufficiency
    23 = 23%
