Abstract: The present invention relates to a compact solar module (CSM) apparatus and a method of producing electricity using such an apparatus in residential buildings for example. One embodiment of the module is made of two arrays of 2×4 solar cells. Each cell in the array has a surface area of 36 square inches for example. Each array covers an area of 1×2 square ft, generating 26.4 Watts of electricity. One CSM of this embodiment consists of 2×8 sub-CSMs, generating a total of 422.24 Watts, and having the assembled dimension of 27.5?×21?×7.6?. The compact feature of solar module relies on sunray transmission to the solar cells and their remote illumination through optical fibers and sets of concave and convex mirrors & lenses. Sunrays are collected and concentrated and condensed on the optical fiber bundles installed in light guides penetrating through a roof top and tracks sunrays during sunrays.

Abstract: The invention is a nonaqueous, single method for processing multiple spent nuclear fuel types by separating the fission- and transuranic products from the nonradioactive and fissile uranium product. The invention has four major operations: exposing the spent fuels to chlorine gas at temperatures preferably greater than 1200.degree. C. to form volatile metal chlorides; removal of the fission product chlorides, transuranic product chlorides, and any nickel chloride and chromium chloride in a molten salt scrubber at approximately 400.degree. C.; fractional condensation of the remaining volatile chlorides at temperatures ranging from 164.degree. C. to 2.degree. C.; and regeneration and recovery of the transferred spent molten salt by vacuum distillation. The residual fission products, transuranic products, and nickel- and chromium chlorides are converted to fluorides or oxides for vitrification.

Abstract: A process for disassociating H.sub.2 S in a gaseous feed using an improved catalytic material in which the feed is contacted at a temperature of at least about 275.degree. C. with a catalyst of rutile nanocrystalline titania having grain sizes in the range of from about 1 to about 100 nanometers. Other transition metal catalysts are disclosed, each of nanocrystalline material with grain sizes in the 1-100 nm range.

Abstract: A method of making a negative electrode, the electrode made thereby and a secondary electrochemical cell using the electrode. Lithium, silicon and nickel is alloyed in a prescribed proportion forming an electroactive material, to provide an improved electrode and cell.
