5.5 Technology in the Industrial Age Notes
Iron Production in the Industrial Age
Mass Production of Iron:
- Coal was essential for powering steam engines and the mass production of iron.
- Improved processes in the 1700s and early 1800s increased iron outputs.
- Introduction of coke enabled larger furnaces for iron production.
Types of Iron:
- Cast Iron: Strong but brittle, challenging to shape.
- Wrought Iron: Patented by Henry Cort in 1794; less strong but more manageable for manufacturing.
The Second Industrial Revolution
Key Players: The United States, Great Britain, and Germany were central to this phase, occurring late 19th to early 20th century.
Innovations:
- Transition from earlier developments (textiles, steam power, iron) to advancements in steel, chemicals, machinery, and electronics.
Steel Production
- Bessemer Process (1856):
- Introduced mass production of steel, an iron-carbon alloy.
- Process involved blasting molten metal with air to remove impurities.
- Enhanced steel's strength and versatility, pivotal for industrial society.
Oil and Kerosene
- Commercial Oil Wells: Emerged mid-1800s tapping vast energy resources.
- Primary Products:
- Initially focused on kerosene for lighting and heating.
- Development in 1847 to extract kerosene led to the rise of the internal combustion engine, affecting automobiles and aviation (early 1900s).
Electrification
- Public Power Stations:
- First in 1882, London; electrification led to street lighting and electric transportation.
- Communication Technologies:
- Telephone: Patented by Alexander Graham Bell in 1876; improved by Edison's voice transmitter design in 1886.
- Radio: Developed through experiments by Gugliemo Marconi; first signal sent across the Atlantic in 1901.
Global Trade and Migration
Communication & Transport Innovations:
- Railroads, steamships, and the telegraph facilitated exploration, development, and global communication.
- Transcontinental Railroad (completed 1869) linked U.S. coasts, promoting industrial growth.
Economic Forces & Colonialism:
- Industrialization created a demand for capital and resources, prompting the establishment of colonies to secure these.
Transformation in Trade Patterns:
- Railroads expanded access beyond coastal areas, promoting trade and migration into interior regions.
- Innovations in communication linked farmers, miners, manufacturers, and customers, integrating global markets.
Key Terms
- Environment: coal, coaling stations
- Technology: Transportation (railroads, steamships), Communication (telephone, telegraph)
- Economy: steam engine, steel, oil, capital
- Society: second industrial revolution
Impact of the Industrial Age
- Ralph Waldo Emerson highlighted technology's role in enhancing production and economic growth.
- The steam and internal combustion engines drastically increased resource access and goods distribution.
The Coal Revolution
- James Watt's Steam Engine (1765):
- Revolutionized coal as a power source, driving machinery in textile factories, eventually powering steam trains too.
Water Transportation Changes
- Steamships: Enabled more reliable and mobile transportation across oceans and rivers; replaced reliance on wind.
- Impact on Trade: Coaling stations became key refueling locations on major trade routes, ensuring efficient travel and commerce.
