Energia infantil
Na África do Sul, uma idéia engenhosa para converter a energia gasta pelas crianças brincando em qualidade de vida para a população em geral. Um gira-gira conectado à um poço artesiando bombeia água para um reservatório enquanto as crianças brincam.

"The children push the merry-go-round again and again. As they run, a device in the ground beneath them begins to turn. With every rotation of the merry-go-round, water is pumped out of a well, up through a pipe, and into a tank high above the playground.
"A few feet away from all the fun, students in uniform turn on a tap. Clean, cold drinking water pours out. This is Motshegofadiwa Primary School, 15 miles north of Pretoria. It’s in a town called Stinkwater; locals say there’s a good reason for that name. The water around here used to smell. School Principal Peter Banyana says the water supply was also erratic before the Play-Pump arrived... Now Banyana says the children can pump enough water for everyone. There are 500 Play-Pumps around South Africa, most of them installed at schools like this one, where students live in poverty and resources are few."
