Appropriate Technology Engineering 305 class
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.
