These technical briefs focus on ways to transport goods and people in a relatively low cost way. This is important to people in the developing world living in remote areas. Technologies include cycle trailers, improved bicycles for load carrying, and aerial ropeways.
Technical briefs are documents produced by Practical Action which are freely available to people in the developing world. They provide detailed technical information on a variety of subjects ranging from how to make jams and pickles to how to build a flood-proof house or an aerial ropeway.
As excellent secondary sources of information students can use technical briefs for research and to analyse and evaluate raw data. They are therefore excellent support materials for the new science national curriculum.
