Matt,
Very interesting concept.
Your calculated yield might be on the high side. How much room is required around the racks vertically (lights, cabling, water supply, space for crop)?
38,400lb of vegetables = ~17,395kg.
At 200kcal/kg (lettuce!) that's 1,391 person-days at 2,500kcal/d*
At 400 (brussel sprouts, carrot, onion), 2,782.
At 1,000 (potato), 6,955
As an alternative upper limit, a 20' ISO container full of rice or corn (25,000kg for ease of calculation) could provide about 34,500 person-days food (at 2,500 kcal/d diet).
* 3,000+ kcal/d a better figure for someone doing lots of hard manual labour/labor. 2,500 is recommended value for men who are sedentary or doing light work.
