Basic Food Production System

We call this a food cell, as in:

  • the cell of a plant that produces food through photosynthesis, as in:
  • a fuel cell, which is a shell that encloses the process of converting hydrogen and oxygen into electricity and water, as in:
  • a membrane that encloses processes that produce protein and fresh vegetables year round, as in:
  • a cell that is missing from the organism that is your neighborhood, as in:
  • our complex system adapting to crises by changing the way human food is produced . . .


In a food cell, green house technology is combined with aquaponics, vermiculture and animal husbandry in a single structure and the byproducts of each process are used as feed stock in the other processes.  It is an integrated system sized to fit in a suburban yard.  Waste is reduced toward zero as a function of how well the processes are integrated.  Cost is reduced toward zero as a function of how much of the input is produced as a byproduct.

Acquaponics System

Basic System Elevation


The system has a "climate battery" to store day time heat in the growing medium.  The water in the fish tanks also serves as thermal mass to keep the cell from freezing on cold nights.


The growing medium is wood chips and manure as in all of our deep mulch gardens.


The growing system grows vegetables year round.  We are still experimenting with enclosures and thermal mass to air space ratios to see if we can grow warm season crops year round.

Basic System Floor Plan


3 intermediate bulk containers are cut down to provide a water tank and bell siphon plant growing tank/ water purification system.


Chicken waste is processed in the worm beds providing worms to feed both fish and chickens.  Worm castings serve as planting medium in the growing beds.


Waste from chicken butchering can be dried and fed to the fish.


The dimensions of this coop are sufficient for about 24 hens depending on how much outdoor space is available.  That would produce enough eggs for about 8 families.  The kitchen scraps produced by the participating families can be an important portion of the food for the chickens.

"This is the best I have been able to do with the general knowledge I possess.  I know that there are people out there a lot smarter than I am.  I challenge you to integrate more species and more functions to produce food with greater integrated efficiency and share what you design with the world."
