2. Gramme machine - Wikipedia

   en.wikipedia.org/wiki/Gramme_machine

   It was the first generator to produce power on a commercial scale for industry. Inspired by a machine invented by Antonio Pacinotti in 1860, Gramme was the developer of a new induced rotor in form of a wire-wrapped ring ( Gramme ring ) and demonstrated this apparatus to the Academy of Sciences in Paris in 1871.

3. Steam–electric power station - Wikipedia

   en.wikipedia.org/wiki/Steam–electric_power_station

   A steam–electric power station is a power station in which the electric generator is steam-driven: water is heated, evaporates, and spins a steam turbine which drives an electric generator. After it passes through the turbine, the steam is condensed in a condenser. The greatest variation in the design of steam–electric power plants is due ...

4. Boiler (power generation) - Wikipedia

   en.wikipedia.org/wiki/Boiler_(power_generation)

   Type of steam generator unit used in coal-fired power plants. The steam generator or steam boiler is an integral component of a steam engine when considered as a prime mover. However it needs to be treated separately, as to some extent a variety of generator types can be combined with a variety of engine units.

5. Passthrough (electronics) - Wikipedia

   en.wikipedia.org/wiki/Passthrough_(electronics)

   VCRs, DVD recorders, etc. act as a "pass-through" for composite video and S-video, though sometimes they act as an RF modulator for use on Channel 3. Tape monitor features allow an AV receiver (sometime the recording device itself) to act as a "pass-through" for audio.

6. Water-tube boiler - Wikipedia

   en.wikipedia.org/wiki/Water-tube_boiler

   The older fire-tube boiler design, in which the water surrounds the heat source and gases from combustion pass through tubes within the water space, is typically a much weaker structure and is rarely used for pressures above 2.4 MPa (350 psi). A significant advantage of the watertube boiler is that there is less chance of a catastrophic failure ...

7. Field coil - Wikipedia

   en.wikipedia.org/wiki/Field_coil

   A field coil is an electromagnet used to generate a magnetic field in an electro-magnetic machine, typically a rotating electrical machine such as a motor or generator. It consists of a coil of wire through which the field current flows. In a rotating machine, the field coils are wound on an iron magnetic core which guides the magnetic field lines.

9. Vircator - Wikipedia

   en.wikipedia.org/wiki/Vircator

   Due to the intensity of the electron beam, many electrons pass through the anode into the region beyond it, forming a virtual cathode. The electron beam must be so intense as to exceed the space charge limiting current in that region, causing oscillations that generate microwaves. The frequency, efficiency and other characteristics of the ...
