P13411: High Temperature Waste Pasteurizer

Systems Design

Table of Contents

Website should document your journey through MSD, so include work-in-progress as well as latest results. Use pdf's for display whenever possible so that information is easily viewable without the need to download files and open applications. (Your EDGE file repository should still contain original files).

Sample categories are listed below, but feel free to change or add nodes to better correspond to your project and your Guide’s expectations.


Capetown Project at WPI - This is a large scale human waste pasteurizer that was tested by Worcester Polytechnic Institute in 1997.

CooKit Solar Cooker - This is a low cost solar cooker that is already used in developing countries. This is the approximate size of the conceptual design.

Concept Development (generation, improvement, selection)

Morph Chart-PDF

Pugh Chart-PDF

Our group went through several stages in determining the concept we were going to choose. In the first phase, brainstorming, we created a Morph Chart listing all of the possible solutions to the needs we had to meet for our client. We then created six concepts, from cheap and durable to expensive and powerful, and ranked them in Pugh Charts against two separate datums, the Capetown Project and an average DIY solar cooker. The final phase took the top three designs from our Pugh Chart and meshed them together to form the concept we have agreed upon above.
