| Edit: I hope to be wrong.

| That sentence right there is worth the read...

| an easy task.

| They say 4 people need 11 tons of food for a 1100 day mission.
| That's 2.5 kg per person per day. It looks like this includes
| water. Water can (and is) recycled in space missions. A lot of
| food in space is dehydrated (you can buy astronaut ice cream at
| any science museum, and it's not that bad). You may get away
| with only 0.5 kg of solid food per person per day.
|
| If they did the same type of generous estimates elsewhere, then
| maybe 100 tons would suffice, instead of 300. And 100 tons is
| how much the Statship is supposed to be able to carry.

| Not to be alarmist but unless you are exaggerating, no mentally
| or physically healthy human being needs that much sleep.

| I wasnt kidding about the duration but other than this

| That said, thanks for pointing it out - it didnt occur to me
| that it could be a symptom of something.
