From Principles of appropriate technology

The Full Belly Project Universal Nut Sheller, an example of appropriate technology.

What makes "appropriate technology" is determined by context. Therefore, none of these are absolute - they are simply common features that make a technology "appropriate" to a world where many suffer a lack of basic necessities, a lack of money, and lack of equipment and technological expertise. They are also technologies that have a gentle impact on the earth:

• Small, as in Small is Beautiful. Small often means affordable and adaptable, and puts the control in the hands of the users. Small also means local, which offers benefits in resilience.
• Few moving parts - less to go wrong (similar to the KISS principle, & the Durable, efficient, stoïc-principle ).
• Can be built locally
• Made with locally available materials
• Easily repaired, by local people with locally available equipment.
• Affordable
• Suitably disposable - locally and not polluting in it's disposal or recycling

The source of the technology doesn't matter much - it matters much more that it is appropriate. While the source of a technology sometimes becomes an issue in discussions of technology for international development, technology from anywhere can have uptake and make an impact, as evidenced by the mobile phone.

I love to see projects that make the world a better place manifest. The way a project manifests from inception, brainstorming, researching, creating, testing, iterating, promoting, etc. always fill me with wonder and excitement. There is no one way that it unfolds, but my favorite ways to be part of are those that are collaborative.
