We offer decentralized unpowered water lifting, using devices that are installed below a water source, such as a spring. The most promising of the water lifting devices of impulse type is a hydraulic ram. If the hydraulic ram is equipped with a suction tube, it is possible to increase the height difference between the source and the lowest point to the most possible value. If the hydraulic ram is equipped with a torque converter it allows: 1) to adapt optimal operating mode of a hydraulic ram to particular geodesic conditions; 2) to create in advance large-scale hydraulic rams and torque converters and to unitize them for each urgent order 3) in the second circuit, i.e. in the torque converter, any medium may be used as the working fluid: water, oil, coolant, air and so on., that helps produce energy and then transform it into useful function at maximum efficiency (≈ 90%) due to the minimal number of the energy conversion forms.
