2. Thermoelectric generator - Wikipedia

   en.wikipedia.org/wiki/Thermoelectric_generator

   Every human activity, transport and industrial process generates waste heat, being possible to harvest residual energy from cars, aircraft, ships, industries and the human body. [1] From cars the main source of energy is the exhaust gas. [32] Harvesting that heat energy using a thermoelectric generator can increase the fuel efficiency of the car.

3. Magnetohydrodynamic generator - Wikipedia

   en.wikipedia.org/wiki/Magnetohydrodynamic_generator

   Diagram of a disk MHD generator showing current flows. The third and, currently, the most efficient design is the Hall effect disc generator. This design currently holds the efficiency and energy density records for MHD generation. A disc generator has fluid flowing between the center of a disc, and a duct wrapped around the edge.

4. Electric generator - Wikipedia

   en.wikipedia.org/wiki/Electric_generator

   U.S. NRC image of a modern steam turbine generator (STG). In electricity generation, a generator [1] is a device that converts motion-based power (potential and kinetic energy) or fuel-based power (chemical energy) into electric power for use in an external circuit.

5. Heat recovery steam generator - Wikipedia

   en.wikipedia.org/wiki/Heat_recovery_steam_generator

   A heat recovery steam generator (HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream, such as a combustion turbine or other waste gas stream. It produces steam that can be used in a process ( cogeneration ) or used to drive a steam turbine ( combined cycle ).

6. Electricity generation - Wikipedia

   en.wikipedia.org/wiki/Electricity_generation

   Electricity generation is the process of generating electric power from sources of primary energy.For utilities in the electric power industry, it is the stage prior to its delivery (transmission, distribution, etc.) to end users or its storage, using for example, the pumped-storage method.

7. Van de Graaff generator - Wikipedia

   en.wikipedia.org/wiki/Van_de_Graaff_generator

   Van de Graaff generator diagram. A simple Van de Graaff generator consists of a belt of rubber (or a similar flexible dielectric material) moving over two rollers of differing material, one of which is surrounded by a hollow metal sphere. A comb-shaped metal electrode with sharp points (2 and 7 in the diagram), is positioned near each roller ...
