The basic principle employed here is the Faraday’s law of electromagnetic induction which involves direct conversion of kinetic energy of a flowing fluid into electricity by passing the conventional multiple conversion process. In the design of the generator, a pipe whose diameter increases from beginning to end is taken. A gas is allowed to flow through this pipe at very high temperature from left to right. A field coil is used to generate a magnetic field in a direction perpendicular to the direction of the motion of the gas. This results in the development of EMF. Gas conductivity can be increased by the addition of small amount of potassium. A two-stage cyclone furnace is used as a combustor. The electrodes used here are made of tungsten cooled with iridium and are separated from one another by beryllia insulating material. The field coil is made of a superconducting material either niobium-zirconium or niobium-tin.
