The Kelvin water dropper, invented by Scottish scientist William Thomson (Lord Kelvin) in 1867, [1] is a type of electrostatic generator. Kelvin referred to the device as his water-dropping condenser. The apparatus is variously called the Kelvin hydroelectric generator, the Kelvin electrostatic generator, or Lord Kelvin's thunderstorm.
The plant, the Cabin Creek Generating station, is a pumped storage hydroelectric generator that opened in 1967. It is located about 6 miles from Georgetown, accessed by the high mountain road of Guanella Pass. It sits at an elevation of greater than 10,000 feet above sea level.
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 total generating capacity of this two-dam complex is 25,215 MW. The Itaipu on the Brazil–Paraguay border has 20 generator units with overall 14,000 MW of installed capacity. However, the maximum number of generating units allowed to operate simultaneously cannot exceed 18 (12,600 MW).
Low-head hydro power refers to the development of hydroelectric power where the head is typically less than 20 metres, although precise definitions vary. [1] Head is the vertical height measured between the hydro intake water level and the water level at the point of discharge.
It is a very simple machine that is still produced today for use in small hydro sites. Segner worked with Euler on some of the early mathematical theories of turbine design. In the 18th century, a Dr. Robert Barker invented a similar reaction hydraulic turbine that became popular as a lecture-hall demonstration. [ 3 ]

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. In 1819 the French engineer Claude Louis Marie Henri Navier (1785–1836) suggested using the Archimedean ...
