Engineering

Technology & Engineering: Topic Page
The use of tools, power, and materials, generally for the purposes of production.
Engineering: Topic Page
Profession devoted to designing, constructing, and operating the structures, machines, and other devices of industry and everyday life
Civil Engineering: Topic Page
Branch of engineering that is concerned with the construction of roads, bridges, airports, aqueducts, waterworks, tunnels, canals, irrigation works, and harbours.
Mechanics: Topic Page
Branch of physics concerned with motion and the forces that tend to cause it; it includes study of the mechanical properties of matter, such as density, elasticity, and viscosity.
Power (Mechanics): Topic Page
In science and engineering, the time rate of doing work or delivering energy.
Machine: Topic Page
Arrangement of moving and stationary mechanical parts used to perform some useful work or to provide transportation. From a historical perspective, many of the first machines were the result of human efforts to improve war-making capabilities; the term engineer at one time had an exclusively military connotation.

Engines

Diesel Engine: Topic Page
Type of internal-combustion engine invented by the German engineer Rudolf Diesel and patented by him in 1892.
Internal Combustion Engine: Topic Page
One in which combustion of the fuel takes place in a confined space, producing expanding gases that are used directly to provide mechanical power.
Petrol Engine: Topic Page
The most commonly used source of power for motor vehicles.
Steam Engine: Topic Page
Engine that uses the power of steam to produce useful work. The first successful steam engine was built in 1712 by English inventor Thomas Newcomen at Dudley, West Midlands.

Energy Sources

Energy Efficiency: Topic Page
When the world speaks about energy, invariably it speaks about energy supplies.
Alternative Energy: Topic Page
At the center of energy issues in the United States is the growing realization that in order to sustain this level of energy consumption, a transition away from fossil fuels to more reliable and sustainable sources is needed.
Biodiesel
From The Columbia Encyclopedia
Fuel made from natural, renewable sources, such as new and used vegetable oils and animal fats, for use in a diesel engine.
Nuclear Energy: Topic Page
The energy stored in the nucleus of an atom and released through fission, fusion, or radioactivity.
Renewable Energy: Topic Page
Renewable energy is the energy produced by using natural resources that will regenerate in time. Primary sources of renewable energy are water, geothermal heat, wind, and sunlight. The energy produced by using different organic materials, such as wood, agricultural rejects, forestry residues, and urban solid waste (called biomass) is also regarded as “renewable.”
Solar Energy: Topic Page
Energy from sunlight is one of the world's most important natural resources. Fossil fuels and agriculture would be impossible without it. Solar power has been used for thousands of years, and the technology continues to evolve.
Water Power: Topic Page
Mechanical energy derived from falling or flowing water, e.g., rivers, streams, and the overflow of dams.
Wind Power: Topic Page
Harnessing of wind energy to produce power. Since the 1970s, advanced aerodynamic designs have been used to build wind turbines that generate electricity.

Generating Power

Dam: Topic Page
Structure built across a river to hold back a body of water (called a reservoir) in order to prevent flooding, provide water for irrigation and storage, and provide hydroelectric power.
Generator: Topic Page
In electricity, machine used to change mechanical energy into electrical energy.
Fuel Cell: Topic Page
Electric cell in which the chemical energy from the oxidation of a gas fuel is converted directly to electrical energy in a continuous process (see oxidation and reduction). MORE
Nuclear Reactor: Topic Page
Device for producing controlled release of nuclear energy.
Turbine: Topic Page
Rotary engine that uses a continuous stream of fluid (gas or liquid) to turn a shaft that can drive machinery.
