Human-powered transport is the transport of person(s) and/or goods using human muscle power. Like animal-powered transport, human-powered transport has existed since time immemorial in the form of walking, running and swimming. Modern technology has allowed machines to enhance human-power. Although motorization has increased speed and load capacity, many forms of human-powered transport remain popular for reasons of lower cost, leisure, physical exercise and environmentalism. Human-powered transport is sometimes the only type available (especially in underdeveloped or inaccessible regions), and is considered an ideal form of sustainable transportation. In the 1989 Race Across America, one team (Team Strawberry) used an experimental device that consisted of a rear wheel hub, a sensor and a handlebar mounted processor. The device measured each cyclist's power output in watts. In lab experiments an average "in-shape" cyclist can produce about 3 watts/kg for more than an hour (e.g.,... less
