“Troubled Waters” – PlayPump
The PlayPump system first gained significant attention in 2005. The concept involves devices similar to merry-go-rounds, which are installed near schools in Southern Africa. The spinning of the device powers a pump, which brings fresh water up from the ground. Excess water can be stored in an overhead tank. Furthermore, the system pays for itself in advertising. In 2006 the United States pledged $10 million to support the project.
