Title: Thermoelectric element
Claims: I claim: 1. A thermo-electric element of the kind comprising two dissimilar annular components, inner and outer electrode means creating a working junction and permitting radial current flow in the dissimilar components wherein the ratio of the outer radius to the inner radius of each of the dissimilar components is within the range of from 4 to 5. 2. A thermo-electric element according to claim 1 wherein the ratio is substantially 4.5. 3. A thermo-electric element according to claim 1 wherein said electrode means comprise a central electrode extending axially through both of the dissimilar components and outer electrodes respectively rimming the dissimilar components. 4. A thermo-electric element of the kind comprising two annular dissimilar components, inner and outer electrode means constituting a working junction and permitting current flow radially in the dissimilar components wherein at least one lateral face of each of the dissimilar components is non-planar and approximates a hyperboloid of revolution. 5. A thermo-electric element according to claim 4 wherein the hyperbola generating said hyperboloid of revolution is defined by the equation Y = 1/2d (Ro)/R where Y is the distance from the median plane of the components, R is the radial co-ordinate and d the thickness of the component at its periphery. 6. A thermo-electric element according to claim 4 wherein the ratio of the outer and inner radii of each element is within the range of 4 to 5.
