Examples of steam power in the following topics:

  • The Spread of Steam Power

  • Industrial Societies: The Birth of the Machine

    • Examples of the technological innovation of the Industrial Revolution include the invention of steam and coal engines.
    • The First Industrial Revolution, which began in the 18th century, merged into the Second Industrial Revolution around 1850, when technological and economic progress gained momentum with the development of steam-powered ships, railways, and later in the 19th century with the internal combustion engine and electrical power generation.
    • The introduction of steam power fuelled primarily by coal, wider utilization of water wheels, and powered machinery—mainly in textile manufacturing —underpinned the dramatic increases in production capacity.
    • The Savery Engine, invented in 1698, was one of the first steam engines available commercially.
  • The Industrial Revolution

    • By the turn of the century, Evans also had developed one of the first high-pressure steam engines and began establishing a network of machine workshops to manufacture and repair these popular inventions.
    • Reliance on horse power for machinery in the United States soon gave way to water power; this resulted in a concentration of industrialization developing in New England and the rest of the northeastern United States, where fast-moving rivers were located.
    • Steam power fueled by coal, wide utilization of water wheels, and powered machinery became common features of the manufacturing industry.
    • This is the original steam engine design patented by Oliver Evans.
  • Are solar voltaics right for your business?

    • If your organization can afford to buy several years of its power in advance while awaiting payback, and if your business is situated in a location that receives adequate sunlight then, yes, solar power may be right for business.
    • Note that energy from the sun can also heat water (and buildings) as well as drive steam turbines.
    • For example, calculations for concentrated solar power, which uses mirrors to concentrate sunlight onto a fluid-filled container to produce steam that drives a turbine, is cost-equivalent to oil priced at $50 per barrel (before payback) – or as low as $20 per barrel (before payback) when the technology is scaled up.

  • Productivity Gains from Technology

    • Railroads evolved from mine carts and the first steam engines were designed specifically for pumping water from mines.
    • Railroads evolved from mine carts and the first steam engines were designed specifically for pumping water from mines.
    • Railroads evolved from mine carts and the first steam engines were designed specifically for pumping water from mines.
    • Replacing human and animal power with water and wind power, steam, electricity and internal combustion, and greatly increasing the use of energy;
  • The Second Industrial Revolution

    • In the same period new systems were introduced, most significantly electrical power and telephones.
    • Railroads also benefited from cheap coal for their steam locomotives.
    • By 1870 the work done by steam engines exceeded that done by animal and human power.
    • Improvements in steam efficiency, like triple-expansion steam engines, allowed ships to carry much more freight than coal, resulting in greatly increased volumes of international trade.
  • Early Steam Engines

  • Electric Generators

    • Possible sources of mechanical energy include: a reciprocating or turbine steam engine , water falling through a turbine or waterwheel, an internal combustion engine, a wind turbine, a hand crank, compressed air, or any other source of mechanical energy.
    • Generators supply almost all of the power for the electric power grids which provide most of the world's electric power.
  • What is Power?

    • In physics, power is the rate of doing work.
    • The unit of power is the joule per second (J/s), known as the watt (in honor of James Watt, the eighteenth-century developer of the steam engine).
    • Power implies that energy is transferred, perhaps changing form.
    • A coal-fired power plant may produce 1,000 megawatts; 1 megawatt (MW) is 106 W of electric power.
    • Tremendous amounts of electric power are generated by coal-fired power plants such as this one in China, but an even larger amount of power goes into heat transfer to the surroundings.
  • Preparing for change

    • Having employees become part-owners in the change process by asking for their input is a powerful way to win them over.
    • The solutions they came up with – on their own included identifying and fixing steam leaks, reducing electricity consumption, super-insulating industrial furnaces and introducing real-time monitoring (immediate feedback from mechanical processes).
