From today's featured article

Bill Mollison talking about the future.
Permaculture is a design system for creating sustainable human environments. The word itself is a contraction not only of permanent and agriculture but also of permanent culture, as cultures cannot survive for long without a sustainable agricultural base and landuse ethic.

Bill MollisonW, Introduction to Permaculture

This is what it looks like when finished.
Welding wood. This is a technique to join wood using scrap tin, such as that from a used can. Needed materials include:

1. Two sticks of wood to be joined.

  • Make sure the wood is in good condition where the connection is to be made. It should be clean, no bits of bark or loose paint, and no knots, as they are too hard for nails.

2. Two pieces of thin tin.

  • For the first bond, use a knife for cutting the tin from a small can for example.
  • Length and width equal to the stick diameter. (more steps follow)

Appropriate technology (AT) is technology that is designed with special consideration to the context of its use - including environmental, ethical, cultural, social, political, and economical aspects of the community it is intended for. With these goals in mind, AT proponents claim their methods require fewer resources, are easier to maintain, and have less of an impact on the environment compared to techniques from mainstream technology, which they contend is wasteful and environmentally polluting.

The term is usually used to describe simple technologies proponents consider suitable for use in developing nations or less developed rural areas of industrialized nations. This form of "appropriate technology" usually prefers labor-intensive solutions over capital-intensive ones, although labor-saving devices are also used where this does not mean high capital or maintenance cost. In practice, appropriate technology is often something described as using the simplest level of technology that can effectively achieve the intended purpose in a particular location. In industrialized nations, the term appropriate technology takes a different meaning, often referring to engineering that takes special consideration of its social and environmental ramifications.
