This is such a great idea.
More than a million South Africans now have safe drinking water thanks to Playpumps - a simple invention that uses the energy generated by children playing on a roundabout to pump groundwater from boreholes.
Playpumps are made from easily available windmill components and a zero-energy water pump and some 700 villages have had Playpumps installed since 1997.
Unlike traditional hand pumps that produce just 150 litres of water an hour to ground level, where it cannot be stored hygienically, Playpumps can pump 1,400 litres of water an hour into a hygienic overhead storage tank.
I came across this when reading a review of the book Design and Landscape for People: New Approaches to Renewal which shows how designers, entrepreneurs and artists are coming together to develop new products with a conscious and with a real purpose.
Great news...
