# What's the minimal space/mass required to feed a human indefinitely with advanced technology?

I know there are similar questions on here already, yet this is different because I don't care about traditional farming in this question.

Environment

This meant for food production on interplanetary and interstellar vessels, space stations and remote outposts. Assume that:

• energy is not an issue

• fertilizers and materials are not an issue due to recycling and mining

• all variables are under control and optimized (CO2, temperature, humidity, ...)

• automation makes labor intensity irrelevant

Given the availability of genetic engineering, vertical farming, bioreactors (for synthetic meat), insects, mushrooms, aquaculture, ... What is the minimum space(1) required to provide a healthy and diverse diet to one person?

(1) Any answer should give the space estimate in $$m^3$$, $$m^2$$ requirement only if relevant, and in addition to this a mass requirement in $$kg$$.

• "bioreactors" meaning what exactly? I can think of several different pieces of technology, real and imagined, that have been called that. – Ash Jul 24 '19 at 12:31

• @user535733 The only tyranny enforcing this kind of food production is that of the rocket equation. – TheDyingOfLight Jul 24 '19 at 15:00
