  2. Magnetohydrodynamic generator - Wikipedia

    en.wikipedia.org/wiki/Magnetohydrodynamic_generator

    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 ...

  3. Magnetohydrodynamics - Wikipedia

    en.wikipedia.org/wiki/Magnetohydrodynamics

    Electron Magnetohydrodynamics (EMHD) describes small scales plasmas when electron motion is much faster than the ion one. The main effects are changes in conservation laws, additional resistivity, importance of electron inertia. Many effects of Electron MHD are similar to effects of the Two fluid MHD and the Hall MHD.

  4. Magnetohydrodynamic converter - Wikipedia

    en.wikipedia.org/wiki/Magnetohydrodynamic_converter

    MHD power generation. A magnetohydrodynamic generator is an MHD converter that transforms the kinetic energy of an electrically conductive fluid, in motion with respect to a steady magnetic field, into electricity. MHD power generation has been tested extensively in the 1960s with liquid metals and plasmas as working fluids.

  5. Magnetohydrodynamic drive - Wikipedia

    en.wikipedia.org/wiki/Magnetohydrodynamic_drive

    Magnetohydrodynamic drive. Yamato 1 on display in Kobe, Japan. The first working full-scale MHD ship. A magnetohydrodynamic drive or MHD accelerator is a method for propelling vehicles using only electric and magnetic fields with no moving parts, accelerating an electrically conductive propellant (liquid or gas) with magnetohydrodynamics.

  6. Magnetic field oscillating amplified thruster - Wikipedia

    en.wikipedia.org/wiki/Magnetic_field_oscillating...

    The magnetic field oscillating amplified thruster (MOA; often named as plasma engine by the media) is a versatile electrothermodynamic system, which is able to accelerate nearly every electrically charged gaseous medium (plasma application) to extremely high velocities, thereby generating a high energetic plasma jet in the exhaust and also electrical conductive fluids (hydrodynamic application ...

  7. Magnetohydrodynamic turbulence - Wikipedia

    en.wikipedia.org/wiki/Magnetohydrodynamic_Turbulence

    Turbulence that concerns the regimes of magnetofluid flow at high Reynolds number. Magnetohydrodynamic turbulence concerns the chaotic regimes of magnetofluid flow at high Reynolds number. Magnetohydrodynamics (MHD) deals with what is a quasi-neutral fluid with very high conductivity. The fluid approximation implies that the focus is on macro ...

  8. Permanent magnet synchronous generator - Wikipedia

    en.wikipedia.org/wiki/Permanent_magnet...

    A permanent magnet synchronous generator is a generator where the excitation field is provided by a permanent magnet instead of a coil. The term synchronous refers here to the fact that the rotor and magnetic field rotate with the same speed, because the magnetic field is generated through a shaft-mounted permanent magnet mechanism, and current is induced into the stationary armature.

  9. Earth battery - Wikipedia

    en.wikipedia.org/wiki/Earth_battery

    An earth battery is a pair of electrodes made of two dissimilar metals, such as iron and copper, which are buried in the soil or immersed in the sea. Earth batteries act as water-activated batteries. If the plates are sufficiently far apart, they can tap telluric currents . [citation needed] Earth batteries are sometimes referred to as telluric ...
