Oasisaw. A Swing To Draw Water From A Well Without Electricity

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