  2. Archimedes' screw - Wikipedia

    en.wikipedia.org/wiki/Archimedes'_screw

    The screw pump is the oldest positive displacement pump. [1] The first records of a water screw, or screw pump, date back to Hellenistic Egypt before the 3rd century BC. [1] [3] The Egyptian screw, used to lift water from the Nile, was composed of tubes wound round a cylinder; as the entire unit rotates, water is lifted within the spiral tube to the higher elevation.

    A screw turbine at a small hydro power plant in Goryn, Poland. The Archimedean screw is an ancient invention, attributed to Archimedes of Syracuse (287–212 BC.), and commonly used to raise water from a watercourse for irrigation purposes.

  4. Mapledurham Watermill - Wikipedia

    en.wikipedia.org/wiki/Mapledurham_Watermill

    In 2011, work started on the installation of a new Archimedes' screw turbine on the river side of the watermill in order to generate electricity. This was built to provide power to Mapledurham House, and replaced a turbine installed in the 1920s that was no longer functional. At the time the turbine was inaugurated in 2012, it was the most ...

    en.wikipedia.org/wiki/Linton_Lock_Hydro

    The screw was installed in 2011 with a capacity to generate 101 kW. [13] A second scheme was proposed soon afterwards and gained approval in 2016 with construction starting in that same year. This scheme involves the world's largest Archimedes Screw used in hydroelectric generation [7] [14] and is situated immediately to the south of the 2012 ...

    The screw pump is commonly attributed to Archimedes on the occasion of his visit to Egypt, but this tradition may reflect only that the apparatus was unknown to the Greeks before Hellenistic times and introduced in his lifetime by unknown Greek engineers.

  7. Reverse overshot water wheel - Wikipedia

    en.wikipedia.org/wiki/Reverse_overshot_water_wheel

    Roman screw used to dewater mines in Spain. Another device which was used widely was the Archimedean screw, and examples of such drainage machines have also been found in many old mines. Depictions show the screws being powered by a human treading on the outer casing to turn the entire apparatus as one piece.

  8. Worm drive - Wikipedia

    en.wikipedia.org/wiki/Worm_drive

    The tightening screw's worm thread engages with the slots on the clamp band. Occasionally a worm drive is designed to run in reverse, resulting in the worm shaft turning much faster than the input. Examples of this may be seen in some hand-cranked centrifuges, blacksmithing forge blower, or the wind governor in a musical box.

  9. Tjasker - Wikipedia

    en.wikipedia.org/wiki/Tjasker

    The tjasker (West Frisian: jasker, German: Fluttermühle) is a small type of windmill used solely for drainage purposes. It is distinctive for its simple construction, featuring only a single inclined shaft that carries the sails on one end and an Archimedes' screw on the other, in this way avoiding the need for any gearing.
