ES102 Lecture Notes - Lecture 5: Internal Combustion Engine, Liquid Fuel, Carbon Cycle
Document Summary
People have found methods to create power in new ways, steam-powered electrical generator, and hydroelectricity, nuclear-powered steam turbine (very expensive and very dangerous). Animals, wood fires, sunlight, whale oil, wind, moving water, etc. Whale boiled down to get oil to power lamps yes lamps. Until industrial revolution, human energy use was almost all from renewable, non-fossil fuel resources. Signifitgant impact on forests and land cover, watercourses. Transformation in 1800"s: steam engine, uses coal to boil water creates pressurized steam that turns a shaft. It allows creation of factories away from watercourses, permits steamships and railways. Liquid fuel is far more portable, lighter and cleaner than coal, burns more efficiently. Permits development of automobiles with internal combustion engines. Less portable than liquid fuels (requires construction from fossil fuels to consumers. By rotating a coiled metal wire within a field. Large amounts of electricity are generated at single points and then distributed along the line.
