Abstract-Open source appropriate technology (OSAT) refers to technologies that provide for sustainable development while being designed in the same fashion as free and opensource software. Facilitated by advances in information technology software and hardware, new ways to disseminate information such as wikis and Internetenabled mobile phones, the global development of OSAT has emerged as a reality. This paper shows the sharing of design processes, appropriate tools, and technical information is enables more effective and rapid development of appropriate technologies for both industrialized and nonindustrialized regions. This sharing will require the appropriate technology community to adopt open standards/licenses, document knowledge, and build on previous work. This paper offers solutions in the form of both business models and tools to overcome technical constraints of OSAT development in the forms of the platforms necessary on which to share and build knowledge about appropriate technologies. These solutions are open, easily accessible for those in need, have a low barrier to entry for both users and information creators, and must be vetted in order to utilized as a trustworthy source on critical information needs. Current progress towards implementing these solutions will be reviewed and recommendations will be made to further increase the rate of OSAT development.
