Patent ID: 6945660

Claim:
A a radiation collector/emitter device, comprising: a stationary toroidal work surface having a rotation axis and including a a polished concave semicircular or parabolic reflecting surface, said concave reflective surface being generated by rotating a generatrix full 360 degrees about said rotation axis on a horizontal plane, the generatrix having an inclined axis and being one of a semicircular arc centered about said inclined axis or a parabolic arc having parabolic arc sections on both sides of said inclined axis, said inclined axis being inclined diagonally outward of said rotation axis and oriented approximately 45 degrees with respect to the horizontal plane, the reflecting surface collecting radiation from a source and concentrating the reflected radiations in a focal perimetrical line inside a curvature radius defined by the concave reflecting surface, and the distance of the perimetrical line from the concave reflecting surface being dependent upon the concavity and orientation or inclination of the reflecting surface.
