is the site for collaborative solutions in sustainability
reduction and international development
through the use of sound principles
and appropriate technology
and the sharing of wisdom and project
information. It is a wiki
, a type of website which allows anyone to add, remove, or edit content. Registration is encouraged but not required for contributors.
Appropedia has been described as an "appropriate technology wiki," but it is much broader than that - it is a green wiki, and a wiki for all matters of international development and aid. But most importantly, Appropedia is an open site for stakeholders to come together to find, create and improve scalable and adaptable solutions. For more about our motivation, see Appropedia:Mission.

Parabolic basket and tin can solar cooker
. The objective of this project is to create a solar cooker
out of local invasive species and waste
materials. We want to create a device that can pasteurize water
and be an alternative to the use of fossil fuels for cooking food
. Our criteria for evaluating the appropriateness of technology are: use of local materials, efficiency, durability, ease of use, ease of construction, cost, impact on environment, impact on culture/lifestyle, education or expertise needed for construction.
Overall this was a successful project. We were able to meet our goal of pasteurizing water. The solar basket can pasteurize water in a quart container in about an hour with optimal conditions. If we were to make the solar basket version 2.0, here are some changes we would make: 1. double up the blackberry runners so that the ribs of the basket are stronger; 2. use another material instead of pampas grass because it causes lumps on the basket's surface, maybe something softer; 3. use all large can lids, of the shiniest quality; and 4.construct the rings that hold the parabolic shape out of a less flexible material than the aluminum and wire that we found.
