    12. Industrial Revolution

Transformation in Transportation交通业, 1700-1800

     English land travel was extremely difficult and costly昂贵,water transportation was much cheaper. ; ---Bristol to Philadelphia---6 pounds.

    ; ---Bristol to 30 mi. inland---6 pounds.

     In 1500, it was much easier to get around环绕France than England (France had built roads for

    military use).

    th In the late 18 century, the English put large amounts of capital资金into building canals运河and

    improving the transportation system.

    ; ---1750-1820, England builds 3k mi of canals.

    Lowers cost of transport.

    Lowers cost of goods.

Betters Bridges and Roads

     Iron Bridge, the birthplace of the Industrial Revolution. Abraham Darby pioneers先锋者the use of cokein ironinstead of charcoal木炭, allows for

    cast iron铸铁.

     World’s first cast iron bridge built in 1781.

     England needs better roads as well.

     Building of turnpikes收费高速公路, which require a toll通行费to travel upon, and people invested

    投资in them to make money.

    ; ---1750: 3.4K mi of turnpikes.

    ; ---1770: 15K mi of turnpikes.

    ; ---1836: 20K mi of turnpikes.

     England’s public roads were built by private funding资金 基金.

     By 1836, England has by far最多the transportation network in the world.

Revolution in Energy, 1650-1800

     Wood had been the main source of energy before 1650. Wood boiled煮沸sea water to make salt, to brewbeer, heat homes取暖, etc and charcoal木炭.

     Before industrialization, wood is renewable可再生. It could be grown fast enough to sustain维持the

    thuse, but by mid-18 century, it is evident显然that wood is in short supply. Production of steeland iron takes huge amounts of trees. To make 378 tons of cast iron铸铁for a

    bridge, it took 4,000 acres英亩 of trees.

     Need new source of energy.


     Without coal, there is no industrial revolution, but there were problems.

     It is possible to make coal from trees, but for 1 ton of coal, you need 1 acre of forest.

     1830, England had only 14m acres under cultivation耕种, but needed much more for railroads,

    iron, etc, had to find a new source of coal.

     By 1870, England is consuming消耗100m tons of coal a year, not enough trees. England did not mine for coal until it was forced to by a timber木材shortage.

Invention of Machine Power

     It is difficult to get coal out of the ground because after digging so far, water table fills up tunnel隧道.

     During the Scientific Revolution, people learned about vacuums真空and suction吸入-hearting water

    can cause a vacuum.

     Thomas Newcomen invented the steam engine蒸汽机in 1715 to remove water from the mines


     It was very slowing, inefficient无效率, and not portable轻便.

Steam Engine

     James Watt worked on steam engines and improved Newcomen’s engine.

    ; ---He created a piston engine活塞发动机.

     Railways had been around for a long time, powered by animals with carts手推车.

     World’s first steam locomotive火车头invented in 1804 in Coldbrookdale, England.

    ; ---Not long before RR travel becomes available for the masses群众,cheaper prices for freight

    meant cheaper prices for goods.

Horizontal Loom水平织布机and the Spinning Wheel手纺车

     Since the middle Ages, people make clothes on loom and wheel at home. Richard Arkwright creates water frame水力织布机, which is several hundred times faster than

    old spinning wheel.

    ; ---Used water power at first, and then by 1780s, it is connected to a steam engine蒸汽机.

     Transforms改造England, making it a huge exporter出口商of textiles纺织品after 1800.

    ; ---England makes world’s textiles纺织原料.

    ; ---Renews更新life in US slavery奴隶with great demand需求for cotton棉花.

Factories 工厂

     First factories appear in England in 1760.

     Water-powered水力, then steam, so now, factories can be located anywhere. All over England, peasants kicked off land, so they went to work in the factories.

     Big textile防治industries as well as steel and iron.

Conclusion 结论

    th By the first decades十年of the 19 century, the industrial Revolution means three things. ; Invention and improvement of the steam engine.

    ; Application of transportation (RR) and to textiles纺织业(factory).

    ; Emergence出现of new modes模式of social organization (factory system). Brings about huge changes in world.
