text: Electrolysers require high currents produced by very low voltages. A homopolar generator has the ability to do this, so in Bockris and Ghoroghchians original experiment in 1985, they followed Faradays idea. Using a magnetic field of 0.86T produced by permanent magnets, they placed a stainless-steel disc in between. The disc needed a rotation speed of 2000 rpm to reach the correct electrical potential for electrolysis. The difference between Faradays original model and Bockris and Ghorogchians is that their disc will only rotate when it is in contact with an electrolyte.
  They encountered one large problem, a viscous force created by the electrolyte, that slowed down the motion of the disc. The two ways they could fix this is to rotate the disc and solution together or increase the magnetic field used. The latter being most practicable, the required magnetic field was calculated according to the power consumption rate or producing a cubic meter of hydrogen. It was discovered a magnetic field of 11T was needed for effective electrolysis, more than 16 times greater than what was originally used. Since superconducting magnets would be required, and they can become too expensive to justify their use, ruling this out as a possible method. 
  Their final decision was to use a homopolar generator as an external source of power. This follows Faraday's method more closely.
  In this method, a pulse potential was created to take advantage of previous studies that give an effectiveness factor of 2 when either a nickel electrode or a Teflon-bonded platinum electrode was used.
  The generator was constructed with a magnetic flux density of 0.6T, a propeller radius of 30 cm and a loop coated with copper strips. To increase the output potential, and reducing the rotation speed required, these were connected in series. Pulses of 2-3V that were sustained for 1ms were achieved.
  This was the first instance of a successful application of pulse electrolysis for the production of hydrogen. However, it still presents its own limitations in the possibility for it to be used in industry.
