human and self powered pumps
follow this link for an excellent collection of tradition pumps, including the self powering hydraulic ram.
A (not as pretty) modern version that looks pretty amazing. Its the "the Super MoneyMaker Pump—yes, that's the real name—sucks up water from sources as many as 30 feet below the ground, can spray it up to 40 feet high, and can even push it through 1,000 feet of hose to cover a larger section of land. In all, the pump can irrigate two acres of land, and costs only around $100". here
