Guizmag.com (http://www.gizmag.com/) is an interesting daily collection of science, technology, and medical articles. I have been saving them for 4 or 5 years (https://www.prismnet.com/~hcexres/beer4/gizmag_notes.html). Listed here are several categories of interest to me, which I hope will give you some ideas for the final report.
These include things like simple, inexpensive devices to purify water, to provide electricity, to enable shelter contruction with local materials, and more. Maybe you can imagine a United Nations agency commissioning you to do a bit of research and write a report on 2 or 3 of these devices. Maybe a nonprofit agency is looking to promote some these devices and commissions you to research and write.
Imagine that WWOOF (http://wwoofinternational.org/) wants to know more about small inexpensive houses using green architecture that they can build for their clients. A report would research and describe 3 or 4 of these which would give WOOFERS and their clients a detailed overview of structures to choose from.
Imagine a national chain gardening store is interested in featuring 3 or 4 of these technologies, offering kits for sales in its stores, and signing up contractors to help in the comnstruction of these things if needed. Research and prepare a report that provides a descriptive overview of these items.
