There is power plant burning heavy dinosaur muscles (Natural gas or Mazut), heating water and making steam, which turns steam turbines and that's conected to generator producing power. Cooling towers is a part of power plant.
The Tainter gate is used in water control dams and locks worldwide. The Upper Mississippi River basin alone has 321 Tainter gates, and the Columbia River basin has 195. A Tainter gate is also used to divert the flow of water to San Fernando Power Plant on the Los Angeles Aqueduct.[1]
A critical factor in Tainter gate design is the amount of stress transferred from the skinplate through the radial arms and to the trunnion, with calculations pertaining to the resulting friction encountered when raising or lowering the gate. Some older systems have had to be modified to allow for frictional forces which the original design did not anticipate.[3] In 1995, too much stress during an opening resulted in a gate failure at Folsom Dam in northern California.
