A magnetohydrodynamic generator ( MHD generator) is a magnetohydrodynamic converter that transforms thermal energy and kinetic energy directly into electricity. An MHD generator, like a conventional generator, relies on moving a conductor through a magnetic field to generate electric current. The MHD generator uses hot conductive ionized gas (a ...
Homopolar generator. Faraday disk, the first 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 ...
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. Sources of mechanical energy include steam turbines, gas ...

In new research, physicists uses principles from quantum mechanics to build a new model of the abstract concept of pi. Or, more accurately, they built a new model that happens to include a great ...
The U.S. Secret Service faced an array of challenges -- and made some potentially dangerous mistakes -- while trying to protect the president, vice president and vice president-elect on Jan. 6 ...
[4] [5] In 1944, a 32-page guide appeared as an article in the same journal. [3] [6] The first edition of the APA Publication Manual was published in 1952 as a 61-page supplement to the Psychological Bulletin, [7] [8] marking the beginning of a recognized "APA style". [3] The initial edition went through two revisions: one in 1957, and one in ...
