Background+Information+and+Problem

Transportation is crucial important for the society. Goods and service can be transported to the market. People need transportation tools to travel long distance tour. For most area, it is very normal that government provide public transportation system. But transportation is a big problem for some Africa countries. They are most developing countries and were colonies during WWII time. Their economy growth is very slow. Governments of these countries can not afford the basic transportation construction, especially for the rural remote areas. Here is a diagram of GDP per capita for Africa countries in year 2007.

So we focus on designing a low-cost transportation tool—solar energy-motivated tricycle, which utilize the local natural solar energy without gasoline refill or other costly energies. It is a feasible solution for improve the local transportation.
