Steam-Energy

Steam power constitutes a crucial power source for industrial society. Water is heated to steam in power plants, and therefore the pressurized steam drives turbines that produce electrical current. The thermal energy of steam is thus converted to energy, which successively is converted into electricity. The steam wont to drive turbogenerators furnishes most of the world’s electrical power . Steam is additionally widely employed in such industrial processes because the manufacture of steel, aluminum, copper, and nickel; the assembly of chemicals; and therefore the refining of petroleum. In the home, steam has long been used for cooking and heating. The practice of lifting loads by mechanical means during building operations goes back at least to Roman times; the Roman architect-engineer Vitruvius in the 1st century BC described lifting platforms that used pulleys and capstans, or windlasses, operated by human, animal, or water power. Steam power constitutes a crucial power source for industrial society. Water is heated to steam in power plants, and therefore the pressurized steam drives turbines that produce electrical current. Steam power was applied to such devices in England by 1800. In the early 19th century a hydraulic lift was introduced, during which the platform was attached to a plunger during a cylinder sunk within the ground below the shaft to a depth equal to the shaft’s height. All these devices employed counterweights to balance the weight of the car, requiring only enough power to raise the load.
