I can't get enough of concepts like this seesaw water pump, which leverages enjoyable activities to produce essential utilities. Jinhyuk Kim's brilliant idea for the OasiSaw was to combine a pump for deep subterranean wells with an old favorite piece of playground equipment. It leverages the standard mechanics of the teeter totter for an efficient resource-reaping system.
Proposed especially for poorer communities, often without fresh water that's easily accessible, this seesaw water-collecting contraption can be positioned wherever there's aqua underfoot. A pipe extending beneath the surface of the earth can be pressurized with this clever technology, drawing liquid up with spurts of force from children swaying back and forth. An hour on the OasiSaw could supply and filter ample clean water for a number of thirsty locals.
