Daily food produced (kg)
1
Calories per person/day567
Food self-sufficiency (%)23%
O2 produced (kg/day)0.6
Water needed (L/day)250
Area for 100% food (m²)221
O2Per Person (%)10%
How to Use This Calculator
- Enter the number of crew members to support.
- Input daily O2 consumption and CO2 production rates per person.
- Set the plant species and growing area dedicated to bioregenerative food and air recycling.
- Review the percentage of oxygen, water, and food needs met by the bioregenerative system.
- Supplement with stored consumables for the gap between bioregenerative output and crew requirements.
How the result changes with Growing area (m²)
| Growing area (m²) | Daily food produced (kg) |
|---|---|
| 101 | 2.02 |
| 351 | 7.02 |
| 650 | 13 |
| 900 | 18 |
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
- Identify Input Parameters4 parametersCrew size = 6, Growing area (m²) = 50, Light hours/day = 16, Primary crop (1-3) = 2 = 4 input(s) provided
- Calculate Daily food producedDaily food produced1 = 1
- Calculate Calories per person/dayCalories per person/day567 = 567
- Calculate Food self-sufficiencyFood self-sufficiency23 = 23%
