Play Pump-innovation from S Africa
At the end of another school day in Acornhoek – a rural community in the semi-arid eastern part of South Africa – children shriek with laughter as they whirl each other around on a colorful merry-go-round. Women carry home buckets of water. But there is more to this scene than meets the eye. Forty meters under ground, each turn of the merry-go-round powers a pump. At 16 rotations per minute, it pumps water effortlessly to a 2,500-liter storage tank, supplying the needs of the entire community at the turn of a tap. Read the fascinating story.
