X Prize For Smallest Self Sustaining Land Area Per Human Inhabitant

Currently you need about 2.5 to 3.5 acres. How small can you go?

Rules are no outside anything other than the original startup. You get a cellphone maybe because a life without the internet isn't worth living, but the program has to be self sustaining. Chickens and their eggs would be a no brainer, they can feed themselves for the most part. Dog would be needed to protect the chickens probably.

The plan would be gauged by something like "nutrition density" or something, and specify the plants, animals, fruits, nuts, berries etc.

Could have one round of modification, but getting too crazy with vertical farming or whatever might not really give you any new info, so basically just using what you gathered pre-technology style. (Except the cellphone and a solar charger.)

Okay, clarification: Bring any technology you want, vertical farming included, but it can only be maintained by what you have on that property, so anything that needs fuel or oil that can't be grown on the property isn't allowed.

I'm allowing robots but think that's probably a bad bet.

       There's not enough definition for this to be useful. By the time you've delineated what "vertical farming kind of stuff" is, there will be too much definition for this to be useful. [+/-]

       Yea, let me get more specific. Stand by…

       Actually, that’s a good point, could you build some kind of high-tech robot that would allow you to live on one city block because it does all the super high tech work? I think I’ll change it to technology that can only be found in the wild. But you get to gather that stuff up by any means necessary and plant it there.   

       Let me think about it, thanks for your patience. This is sort of 1/4th baked, let you know when it's up to half.

       Needs way more preheating [-]

       Nooooooooo! ok.   

       Now just to be clear, this is an idea for a contest to find the best way to do it, not a suggestion HOW to do it right?

       Self-sustaining for how long? Will it be sealed-off from the atmosphere (I'm thinking wind-blown seeds etc) & water (both in & out)?

       It’s be open for rain & sun. Of course the location would have to be accounted for, climate zone & such.
