In this paper the results are presented of a environmental benchmarking study of 4 portable radios, 2 of these radios are powered by an alternative system, the others are powered by batteries. The study shows that there is considerable room for the improvement of both electronics and (human powered) alternative energy systems. It also shows an interesting environmental trade off between the use of batteries and alternative energy sources. The analysis of these four radios is a first result in a research project at DUT on the subject of ‘human powered energy systems in consumer products’. Ongoing research on this subject will focus on the analysis of physical constraints of the human body, new systems for converting human power into electricity, possibilities for the application of these systems in consumer products and assessment of the environmental consequences.
