Reinventing the Tuktuk

In large cities across Asia, auto rickshaws (tuktuks) are one of the most important means of transportation. These tuktuks produce considerable CO2 emissions and air pollution, and their drivers are underpaid. Students participating in the Hybrid Auto Rickshaw project sought to cut CO2 emissions by 40%, while improving the economic positions of drivers.
