ABSTRACT:
A solar powered cutting, shaping, and polishing device is disclosed. In the preferred embodiment a large concave parabolic reflector is mounted on an X and Y axis rotatable (telescope type) mount and directed towards the sun. A smaller convex parabolic reflector is mounted on an adjustable support structure attached to the large concave reflector such that the two reflectors can be made to share, or nearly share, the same focal point. Mounted between the large and small parabolic reflectors on an additional rotatable mount is a flat reflector. The large and small parabolic reflectors are used to concentrate solar energy to a desired and adjustable focal point. The flat reflector can then be used to direct the concentrated energy across a material in an operator-determined pattern. Depending on certain factors associated with the material and the positioning of the focal point, the material can then be cut, shaped, or polished as the user desires. Also disclosed is the use of lenses to perform the concentrating function.
