  2. Line array - Wikipedia

    en.wikipedia.org/wiki/Line_array

    A line array is a loudspeaker system that is made up of a number of usually identical loudspeaker elements mounted in a line and fed in phase, to create a near-line source of sound. The distance between adjacent drivers is close enough that they constructively interfere with each other to send sound waves farther than traditional horn-loaded ...

  3. Ivanpah Solar Power Facility - Wikipedia

    en.wikipedia.org/wiki/Ivanpah_Solar_Power_Facility

    It is located at the base of Clark Mountain in California, across the state line from Primm, Nevada. The plant has a gross capacity of 392 megawatts (MW). [ 8 ] It uses 173,500 heliostats , each with two mirrors focusing solar energy on boilers located on three 459-foot-tall (140 m) [ 9 ] solar power towers . [ 8 ]

  4. Butler matrix - Wikipedia

    en.wikipedia.org/wiki/Butler_matrix

    A linear antenna array will produce a beam perpendicular to the line of elements (broadside beam) if they are all fed in phase. If they are fed with a phase change between elements of then a beam in the direction of the line (endfire beam) will be produced.

    en.wikipedia.org/wiki/Highbank_Power_Station

    The generator installed was the largest single generating unit in New Zealand at the time of its installation. [5] [6] The single vertical shaft generator is driven by a 36,000 bhp (27 MW) Francis turbine. The English Electric generator is a 20‑pole unit rated for 26.5 MW output with a synchronous speed of 300 rpm.

  6. Radioisotope thermoelectric generator - Wikipedia

    Diagram of an RTG used on the Cassini probe. A radioisotope thermoelectric generator (RTG, RITEG), sometimes referred to as a radioisotope power system (RPS), is a type of nuclear battery that uses an array of thermocouples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck effect.

  7. Electric generator - Wikipedia

    en.wikipedia.org/wiki/Electric_generator

    An engine-generator is the combination of an electrical generator and an engine (prime mover) mounted together to form a single piece of self-contained equipment. The engines used are usually piston engines, but gas turbines can also be used, and there are even hybrid diesel-gas units, called dual-fuel units.

  8. Homopolar generator - Wikipedia

    en.wikipedia.org/wiki/Homopolar_generator

    A homopolar generator is a DC electrical generator comprising an electrically conductive disc or cylinder rotating in a plane perpendicular to a uniform static magnetic field. A potential difference is created between the center of the disc and the rim (or ends of the cylinder) with an electrical polarity that depends on the direction of ...

  9. Solar power tower - Wikipedia

    en.wikipedia.org/wiki/Solar_power_tower

    It uses an array of flat, movable mirrors (called heliostats) to focus the sun's rays upon a collector tower (the target). Concentrating Solar Power (CSP) systems are seen as one viable solution for renewable, pollution-free energy. [1] Early designs used these focused rays to heat water and used the resulting steam to power a turbine.
