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.
Platt's roving frame, c. 1858. Cotton-spinning machinery is machines which process (or spin) prepared cotton roving into workable yarn or thread. [ 1] Such machinery can be dated back centuries. During the 18th and 19th centuries, as part of the Industrial Revolution cotton-spinning machinery was developed to bring mass production to the cotton ...

The Pelton wheel or Pelton Turbine is an impulse -type water turbine invented by American inventor Lester Allan Pelton in the 1870s. [ 1][ 2] The Pelton wheel extracts energy from the impulse of moving water, as opposed to water's dead weight like the traditional overshot water wheel. Many earlier variations of impulse turbines existed, but ...

Dynamo. "Dynamo Electric Machine" (end view, partly section, U.S. patent 284,110) A dynamo is an electrical generator that creates direct current using a commutator. Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based ...
Random number generation is a process by which, often by means of a random number generator ( RNG ), a sequence of numbers or symbols that cannot be reasonably predicted better than by random chance is generated. This means that the particular outcome sequence will contain some patterns detectable in hindsight but impossible to foresee.
The Kaplan turbine was an evolution of the Francis turbine. Its invention allowed efficient power production in low- head applications which was not possible with Francis turbines. The head ranges from 10 to 70 metres (33 to 230 ft) and the output ranges from 5 to 200 MW. Runner diameters are between 2 and 11 metres (6 ft 7 in and 36 ft 1 in).
