Open-source appropriate technologies


Open source appropriate technology (OSAT) is appropriate technology designed in the same fashion as free and open-source software. OSAT refers to, on the one hand, technology designed with special consideration to the environmental, ethical, cultural, social, political, and economic aspects of the community it is intended for. On the other hand, OSAT is developed in the open and licensed in such a way as to allow their designs to be used, modified and distributed freely.

Open source is a development method for appropriate technology that harnesses the power of distributed peer review and transparency of process. Appropedia is an example of open-source appropriate technology. There anyone can both learn how to make and use AT free of concerns about patents. At the same time anyone can also add to the collective open-source knowledge base by contributing ideas, observations, experimental data, deployment logs, etc. It has been claimed that the potential for open-source-appropriate technology to drive applied sustainability is enormous. The built in continuous peer-review can result in better quality, higher reliability, and more flexibility than conventional design/patenting of technologies. The free nature of the knowledge also obviously provides lower costs, particularly for those technologies that do not benefit to a large degree from scale of manufacture. Finally, OSAT also enables the end to predatory intellectual property lock-in. This is particularly important in the context of technology focused on relieving suffering and saving lives in the developing world.

The "open-source" model can act as a driver of sustainable development. There are (at least) three good reasons:

for solutions, many researchers, companies, and academics do work on products meant to assist sustainable development. Vinay Gupta has suggested that those developers agree to three principles:

The ethics of information sharing in this context has been explored in depth.

Appropriate technology is designed to promote decentralized, labor-intensive, energy-efficient and environmentally sound businesses. Carroll Pursell says that the movement declined from 1965 to 1985, due to an inability to counter advocates of agribusiness, large private utilities, and multinational construction companies. Recently (2011), several barriers to OSAT deployment have been identified:
