Bernard Kiwia: Tanzania's bicycle mechanic turned inventor
It is often said that African entrepreneurs are solution seekers and none more so than Bernard Kiwia.
While spending most of his time repairing bicycles, he had an idea about how he could use pedal power to create products to help make improvements to the lives of people in his community.
Now a social entrepreneur, he has created products such as solar water heaters and drip irrigation kits. Africa Business Report visited him in Arusha, Tanzania, to talk about his innovative designs.
