OasiSaw.  A swing to draw water from a well without electricity

OasiSaw is an innovative system that uses the energy generated by a swing to extract groundwater. The iconic seesaw design harnesses the energy generated during play to power the pump, a pump that incorporates a carbon nanotube water filter. Playing produces clean, potable water for communities without access to electricity.
