US Patent 7439629 Asynchronous generator with galvano-magnetic-thermal effect

The generator includes:elements (4, 10) for generating a magnetic field in a first direction,a hot source (6) and a cold source (8) creating a temperature gradient (∇T) in a second direction substantially perpendicular to the first direction, andat least one element (2; 14) having thermoelectric conversion properties, disposed in a plane substantially perpendicular to the direction of the temperature gradient (∇T). The magnetic field generated is a field of traveling waves moving in the second direction. Each element having thermoelectric conversion properties has a continuous form in the plane perpendicular to the second direction.
