Donkey-drawn carriages are apparently popular forms of transportation in many countries in Africa. A company known as Water and Wheel has added a new techno-twist to this old concept: solar cells. The cells charge a 12 Volt battery, which in turn can power mobile communications and water filtration systems. In addition to being a huge help to the passengers, the system was also designed with income in mind. In more urban settings, the cart can be used as a kiosk or a small shop, even when the sun goes down. The devices are known as "Happys", which stands for Human and Animal Powered Vehicles.
