A Reddit user over in r/ColonizeMars (u/3015) caught multiple errors in my menu planning sheet. (thread) These affected power, area and volume calculations. I've corrected these errors; the sheet is updated anywhere it is linked.The per-person volume is still about 45 m³. The sheet now tracks 'tray' area and 'floor' area separately, with estimates of floor area required for a set of ceiling heights.Most important is the power requirement for lighting. This increased significantly, from 5.7 kW per person to 22 kW per person.
