Barriers To Appropriate Technology Growth In Sustainable Development, Ivana Zelenika, Joshua M. Pearce Oct 2015

Barriers To Appropriate Technology Growth In Sustainable Development, Ivana Zelenika, Joshua M. Pearce

Joshua M. Pearce

Given the urgency of development problems world-wide, as well as the opportunities of open source appropriate technology (OSAT) to help expedite sustainable development goals, a better understanding of the barriers limiting the scaling of OSAT is needed. In this study, key organizations and researchers working in the field of appropriate technology (AT) were interviewed to identify barriers to OSAT. The data was analyzed via pattern coding and content analysis. Results reveal that among the most pressing problems for those working in the field of AT were the need for better communication and collaboration between the agencies and communities to share …

Viability Of Small-Scale Arsenic-Contaminated Water Purification Technologies For Sustainable Development In Pakistan, Fatima Hashmi, Joshua M. Pearce Dec 2010

Viability Of Small-Scale Arsenic-Contaminated Water Purification Technologies For Sustainable Development In Pakistan, Fatima Hashmi, Joshua M. Pearce

Joshua M. Pearce

Drinking arsenic-contaminated water leads to a series of health problems that has limited development for the largely poor rural people of Pakistan who are unable to afford bottled water, centralized treatment plants or expensive water filter systems. This paper reviews the available appropriate technologies for the removal of arsenic from drinking water to assist in just sustainable development in Pakistan. Several technologies were found to be both technically and economically viable, supporting the large-scale deployment of these small-scale, appropriate technologies. The economic viability determined in this study was based on both first costs and operating costs. The cost of implementing …

3-D Printing Of Open Source Appropriate Technologies For Self-Directed Sustainable Development, Joshua M. Pearce, Christine Morris Blair, Kristen J. Laciak, Rob Andrews, Amir Nosrat, Ivana Zelenika-Zovko Nov 2010

3-D Printing Of Open Source Appropriate Technologies For Self-Directed Sustainable Development, Joshua M. Pearce, Christine Morris Blair, Kristen J. Laciak, Rob Andrews, Amir Nosrat, Ivana Zelenika-Zovko

Joshua M. Pearce

The technological evolution of the 3-D printer, widespread internet access and inexpensive computing has made a new means of open design capable of accelerating self-directed sustainable development. This study critically examines how open source 3-D printers, such as the RepRap and Fab@home, enable the use of designs in the public domain to fabricate open source appropriate technology (OSAT), which are easily and economically made from readily available resources by local communities to meet their needs. The current capabilities of open source 3-D printers is reviewed and a new classification scheme is proposed for OSATs that are technically feasible and economically …
