Another way of looking at this is that--while it doesn't have to be edible--you have to grow plant matter inside your house at a rate equivalent to what everyone in there consumes as food. Even if you found like an algae or something that converted CO2, light, and water into fat, 2400 kCal would be ~300g per person, per day, or not too short of a normal package of butter. |
