  2. Hydraulic ram - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_ram

    These ratios assume 100% energy efficiency. Actual water delivered will be further reduced by the energy efficiency factor. In the above example, if the energy efficiency is 70%, the water delivered will be 70% of 20%, i.e. 14%. Assuming a 2-to-1 supply-head-to-delivery-head ratio and 70% efficiency, the delivered water would be 70% of 50%, i.e ...

  3. Atmospheric water generator - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_water_generator

    State-of-the-art AWG for home use. An atmospheric water generator (AWG), is a device that extracts water from humid ambient air, producing potable water. Water vapor in the air can be extracted either by condensation - cooling the air below its dew point, exposing the air to desiccants, using membranes that only pass water vapor, collecting fog, [1] or pressurizing the air.

  4. Solar-powered pump - Wikipedia

    en.wikipedia.org/wiki/Solar-powered_pump

    A windpump replaced by a solar-powered pump at a water hole in the Augrabies Falls National Park. [Notes 1] This solar water pump up to 3.7 kW is useful for farmers.Solar-powered pumps run on electricity generated by photovoltaic (PV) panels or the radiated thermal energy available from collected sunlight as opposed to grid electricity- or diesel-run water pumps. [1]

  5. Water pumping - Wikipedia

    en.wikipedia.org/wiki/Water_pumping

    This is true whether the water is drawn from a fresh source, moved to a needed location, purified, or used for irrigation, washing, or sewage treatment, or for evacuating water from an undesirable location. Regardless of the outcome, the energy required to pump water is an extremely demanding component of water consumption. All other processes ...

  6. Solar desalination - Wikipedia

    en.wikipedia.org/wiki/Solar_desalination

    Solar desalination is a technique that harnesses solar energy to convert saline water into fresh water, making it suitable for human consumption and irrigation. The process can be categorized based on the type of solar energy source utilized.

  7. Water turbine - Wikipedia

    en.wikipedia.org/wiki/Water_turbine

    The runner of the small water turbine. A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work. Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids. Now, they are mostly used for electric power generation.

  8. Roundabout PlayPump - Wikipedia

    en.wikipedia.org/wiki/Roundabout_PlayPump

    The PlayPump water system is a playground merry-go-round attached to a water pump. The spinning motion pumps underground water into a 2,500-liter tank raised seven meters above ground. The water in the tank is easily dispensed by a tap valve. According to the manufacturer the pump can raise up to 1400 liters of water per hour from a depth of 40 ...

  9. Pump as turbine - Wikipedia

    en.wikipedia.org/wiki/Pump_As_Turbine

    A pump as turbine (PAT), also known as a pump in reverse, is an unconventional type of reaction water turbine, which behaves in a similar manner to that of a Francis turbine. The function of a PAT is comparable to that of any turbine , to convert kinetic and pressure energy of the fluid into mechanical energy of the runner.
