Prototype of Nutsy
FBP Nutsy. The Full Belly Project (FBP), has designed a Universal Nut Sheller (UNS) that are distributing throughout West Africa and Haiti. The UNS shells large amounts of nuts in a fraction of the time that it would take a single person.

Our Engr215 Introduction to Design class from Humboldt State University was divided into seven teams, each consisting of four members. Each team was given one of three assignments:

  • Create a smaller version of the UNS to be marketed in the US in order to fund FBP's efforts abroad.
  • Find a way to make a UNS out of cheaper, lighter and more sustainable materials for the countries of West Africa.
  • Find a way to make molds out of recycled plastic bags for the working parts of the UNS using extremely limited resources in Haiti.

Our team worked on the first of these assignments by redesigning the UNS to be marketable in the United States.

Home biogas system (Philippine BioDigesters)

"It can be built as a : Do-It-Yourself (DIY) project where expert masonry skills are not required" and "by using common and inexpensive materials available anywhere."

Visit the Appropriate technology Portal

A windmill is used to power a water pump which fills a swimming pool.
Appropriate technology (AT) is technology that is designed with special consideration to the context of its use - including environmental, ethical, cultural, social, political, and economical aspects of the community it is intended for. With these goals in mind, AT proponents claim their methods require fewer resources, are easier to maintain, and have less of an impact on the environment compared to techniques from mainstream technology, which they contend is wasteful and environmentally polluting.

The term is usually used to describe simple technologies proponents consider suitable for use in developing nations or less developed rural areas of industrialized nations. This form of "appropriate technology" usually prefers labor-intensive solutions over capital-intensive ones, although labor-saving devices are also used where this does not mean high capital or maintenance cost. In practice, appropriate technology is often something described as using the simplest level of technology that can effectively achieve the intended purpose in a particular location. In industrialized nations, the term appropriate technology takes a different meaning, often referring to engineering that takes special consideration of its social and environmental ramifications.
