Abstract
This invention is a novel technique for making a solar energy collector in a fresnel configuration by using unique hot-wire tools. This process uses either a hot-wire radial cutter to produce concentric grooves and a hot-wire beveled cutter to produce angled concentric surfaces in a base material in combination, or a hot-wire combination cutter to simultaneously produce a single concentric and angled concentric surface in a base material. This shaped base material is now suitable for affixing reflective material.
