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).
 * Can be built locally;
 * Easily repaired, by local people with locally available equipment;
 * Affordable; and
 * Made with locally available materials.

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.
