A pico hydro system made by the Sustainable Vision project from Baylor University [1]. Pico hydro is a term used for hydroelectric power generation of under 5 kW. These generators have proven to be useful in small, remote communities that require only a small amount of electricity – for example, to power one or two fluorescent light bulbs and a TV or radio in 50 or so homes.

The coil pump, if fitted with a suitable rotating seal, can deliver water to a greater height, typically 5-10m, above their discharge opening. [2] Despite the emergence of new pumps that operate on other principles, the coil pump remains an important tool as some of it other benefits are that they can be built and repaired easily at a very low ...
Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface water (e.g., irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (e.g., potable water pumping ...
The bucket and rope system is not compatible with the use of a cover slab, which can prevent pollution of groundwater. In addition, unwashed hands can contaminate the bucket and rope. Hand pumps avoid these issues and are therefore preferable. [1] However, villagers did not stop using traditional means of gathering water during this project.
Toward the end of the 19th century, interest waned as electricity and electric pumps became widely available. Priestly's Hydraulic Ram, built in 1890 in Idaho, was a "marvelous" invention, apparently independent, which lifted water 110 feet (34 m) to provide irrigation. The ram survives and is listed on the U.S. National Register of Historic ...
A small, electrically powered pump A large, electrically driven pump for waterworks near the Hengsteysee, Germany. A pump is a device that moves fluids (liquids or gases), or sometimes slurries, [1] by mechanical action, typically converted from electrical energy into hydraulic or pneumatic energy.
