The microfactory is a set of tools and machines that can be reasonably acquired or built from abundant materials with the goal of enabling humanity to transcend scarcity and poverty.

A factory has inputs and outputs. The decision of which tools and machines comprise the microfactory is a function of the available inputs and the expected outputs, including the requirement of self-replication.

These are my personal notes and are not intended to be a representation of current or future projects of OSE.

Inputs

Criteria for selecting inputs for the microfactory:

• abundant: it should be easy to acquire useful amounts of the material for free or at insignificant cost
• safe: acquiring, handling and processing the material should not be inherently dangerous; common mistakes should be reasonably forgiving
• appropriate: see https://en.wikipedia.org/wiki/Appropriate_technology

The following materials have been selected as inputs for the stated criteria:

Wood

• renewable material that is abundant and free if harvested from your own property
• wood has been used by humans for thousands of years and can be safely worked with primitive tools
• many existing methods, tools and knowledge on working this material

Plastic

• PET soda bottles and HDPE milk jugs are everywhere
• used for storing food, is expected to be safe
• it's only in the last decade that this material has become appropriate for a home based microfactory. methods, tools and knowledge is still at early stages
  • https://preciousplastic.com/

Aluminum

• soda cans are everywhere, aluminum scraps are also abundant
• much lower melting temperature than steel, home made foundries for aluminum are popular
• requires access to User:Lex_Berezhny/Factory to create steel tools strong enough to manipulate aluminum

Glass

• glass is found everywhere
• can be worked with limited tools

Outputs

Self-Replication

Using the Microfactory and with some access to a User:Lex_Berezhny/Factory Factory or to a marketplace where steel components can be purchased it should be possible to produce another duplicate Microfactory.

Electronics

• laptop, tablet, phone, etc

Dryer

• traditional tumble drying
• automated hang drier

Folding Machine
