One-week habitation of two humans in an airtight facility with two goats and 23 crops – Analysis of carbon, oxygen, and water circulation

Agriculture for Space: People and Places Paving the Way

“…Some areas used natural sunlight with supplemental electric lighting, while others only used electric lamps, such as high pressure sodium (Tako et al, 2010). Two-person crews lived inside the facility for 1-week, 2-week, or 4-week tests, eating foods grown inside the facility (Masuda et al, 2005;Tako et al, 2008Tako et al, , 2010. Rice, soybean and peanut were some of the major crops used for these studies (Fig.…”

“…CEEF was part of the Institute for Environmental Sciences (IES) developed to track radio isotopes through closed ecosystems. When not in use for their primary studies, the facilities could be utilized for studies of controlled environment agriculture and human life support (Nitta et al, 2000;Tako et al, 2001Tako et al, , 2008Tako, 2010). CEEF researchers designed complete diets from crops grown in 150 m 2 of the plant cultivation modules (Masuda et al, 2005;Tako et al, 2010.).…”

“…In addition to the humans, two miniature goats were enclosed in the system and were fed inedible parts (leaves and stems) of the crops (Tako et al, 2008(Tako et al, , 2010 [174,175]. Findings from CEEF documented diff erences in assimilation or photosynthetic quotients (CO 2 ixed/O 2 produced) of carbohydrate crops like rice (AQ = 0.95) and fat/protein producing crops like soybean (AQ = 0.87) (Tako et al, 2010) 175].…”
