Re: Village in a box

6 kg per person per day food
365.25 days per year

15,000 kg per ha per year food

Implies 6.84 people per hectare

6.84 billion people

Implies 1 billion ha are needed.

10 million square km.

That's a disk 3,600 km in diameter.

The great Saharan Desert covers 9 million sq km.

Low cost is important. And low labor inputs. Is it
possible to increase food output per labor hour input?

Enclosing space can be done cheaply. Thin films of
PET or similar plastic, fabricated with desirable optical
properties can cover square meters for pennies.

Getting fresh water from the Atlantic, Indian and
Meditteranean at low cost is a challenge. But low
cost solar makes it doable. Atomizing water and
delivering it with mist rather than hydroponics
reduces water usage.. but there is a minimum
each plant and animal species needs.

Better politically organized, are;

Australia is 7.5 million km2
China is 9.6 million km2

Creating 4 food production units 1800 km in diameter
using inflatable enclosed agriculture and intensive
techniques, powered by beamed energy from space

is an alternative to the 37 million villages envisioned at
the outset.
