I saw this cool idea on Guy Kawasaki’s blog. Getting clean water is a big problem in developing countries. Streams are not always clean, carrying the water is hard and the villagers don’t have the resources to run a pump to get at the ground water. PlayPumps is a simple idea of connecting a children’s carousel to a water pump and providing water for a whole village as the children play.
I recently saw an article on a device to create electricty as you walk. My first thought was how daft this contracption would look strapped to my leg. I think that pumping water as you play is definitely cooler. It has me thinking… could we power our neighbourhood from the swingset in the local park?
