Magnetic river is an electrodynamic magnetic levitation (maglev) system designed by Fredrick Eastham and Eric Laithwaite in 1974. It consists of a thin conductive plate on an AC linear induction motor. Due to the transverse flux and the geometry, this gives it lift, stability and propulsion as well as being relatively [vague] efficient. The ...
The Faraday generator is named for Michael Faraday's experiments on moving charged particles in the Thames River. A simple Faraday generator consists of a wedge-shaped pipe or tube of some non-conductive material. When an electrically conductive fluid flows through the tube, in the presence of a significant perpendicular magnetic field, a ...
In 2014, ORPC built and operated its RivGen Power System, the Company’s first river energy project, delivering power to the remote Alaskan village of Igiugig. [ 30 ] An updated RivGen Power System was re-installed and operated in Igiugig in 2015 to demonstrate its latest technology advancements and provided one-third of the community’s ...
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. [7]
Breakdown of ideal MHD (in the form of magnetic reconnection) is known to be the likely cause of solar flares. The magnetic field in a solar active region over a sunspot can store energy that is released suddenly as a burst of motion, X-rays, and radiation when the main current sheet collapses, reconnecting the field.

Illustration of the right-hand rule for the Lorentz force, cross product of an electric current with a magnetic field. The working principle involves the acceleration of an electrically conductive fluid (which can be a liquid or an ionized gas called a plasma) by the Lorentz force, resulting from the cross product of an electric current (motion of charge carriers accelerated by an electric ...
The team put a UV light-absorbing panel on top of a floating solar vapour generator – which harvests the sun’s energy to purify polluted or salty water, and produce the green hydrogen.
The magnetic field of the dynamo or alternator can be provided by either wire windings called field coils or permanent magnets. Electrically-excited generators include an excitation system to produce the field flux. A generator using permanent magnets (PMs) is sometimes called a magneto, or a permanent magnet synchronous generator (PMSG).
