ABSTRACT:
This invention provides a manner to achieve affordable solar energy, as well as other technologies. It does so by improving control grids (for addressing and alignment) in solar concentrators and optical equipment in general. Thus troublesome and expensive grid material like Indium Tin Oxide (ITO) can be replaced by more manageable, hardier, and more cost effective nanotubes; or a carbon grid simply laid down by ordinary photocopy (Xerographic) reduction techniques. The instant invention relates to improvements in the control (addressing and alignment) grid for Solar Energy Concentrators; and similar equipment such as Optical Switches; and Display devices such as Dynamic Reflection, Illumination, and Projection equipment; as well as display equipment in general. The control grid acts to address and align active optical elements such as mirrored balls, multipainted balls, electrophoretic, and magnetophoretic cells in solar concentrators; and in other equipment. Fabrication of the grids is also described.
