The most prevalent hydraulic pump used in maritime situations in ancient Rome was the bilge pump, which functioned to siphon collected water out of a ship's hull (Oleson 1984). The bilge pump was an improvement on the first hydraulic pumps used in antiquity: force pumps.
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.
The 19th-century British system used water-filled pipes to effect changes to the water level in the receiver unit (similar to a transparent water-filled flexible tube used as a level indicator), thus limiting its range to the hydraulic pressure that could be generated at the transmitter's device.

Being so light, an operator can carry the light craft over the shoulder. They are capable of operating in mere inches of water due to the keel-less hull. The early people of Wales used these boats for fishing and light travel and updated models are still in use to this day on the rivers of Scotland and Wales. Early Britons also used the dugout ...
A loutrophoros (Ancient Greek: λουτροφόρος, romanized: loutrophóros, lit. 'loutrophoros'; Greek etymology: λουτρόν/loutron and φέρω/pherō, English translation: "bathwater" and "carry") is a distinctive type of Greek pottery vessel characterized by an elongated neck with two handles.
Island hopping. In the summer of 2022, REGENT tested a quarter-scale prototype of its seaglider — a remotely operated version weighing 400 pounds, with a wingspan of 18 feet. The full-scale ...
Shadoof in Estonia. A shadoof or shaduf, [1] well pole, well sweep, sweep, [2] swape, [3] or simply a lift [4] is a tool that is used to lift water from a well or another water source onto land or into another waterway or basin.
They raise 200,000 litres of water per hour (52,800 US gallons). [10] The wheel takes one minute to complete a revolution, much longer than smaller norias. [10] To drive a wheel bearing such a weight of water, an extraordinarily long weir at a very acute angle was built to concentrate the power of the river on the base of the wheel.
