Harnessing the energy of youth !
Frans Johansson has a brief blog entry about PlayPumps, which harnesses the energy of kids at play to create and store potable water:
Clean water. It is the key for public health and for fighting infectious disease. The question for some parts of the world with few resources is how to get it out of the ground. PlayPumps is a non-profit that has connected the sounds of playground laughter with groundwater to change villages in Sub-Saharan Africa.
Johansson makes a nice point about this being an "intersectional innovation" - numerous times I've watched my daughter with a bunch of other kids at a playground and said "if there was only some way I could bottle all that energy"?
