Beaming Sonny Home
Fortune hadn't been particularly kind to Mattie Gifford Her mother committed suicide, her husband slept around town, her best friend slept with her husband, and she can't stand her three daughters But she does love her son, Sonny, who, nevertheless, plunges her into deep despair when he takes two women and a poodle hostage in a trailer park. Sonny claims to have seen John Lennon's face in an apparition and gets his own mug on the television news. All this is almost too much for Mattie, who stands at the center of this humorous but also poignant tale of disappointment and love..

Spacecraft Power Beaming and Solar Cell Annealing Using High-Energy Lasers
This is a NAVAL POSTGRADUATE SCHOOL MONTEREY CA DEPT OF AERONAUTICS AND ASTRONAUTICS report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A561114. The abstract provided by the Pentagon follows: Satellite lifetime is often limited by degradation of the electrical power subsystem--radiation-damaged solar arrays and failed batteries, Being able to beam power from terrestrial sites could alleviate this limitation, extending the lifetime of billions of dollars of satellite assets, as well as providing additional energy for electric propulsion that can be used for stationkeeping and orbital changes In addition, laboratory research at the Naval Postgraduate School (NPS) has shown the potential to anneal damaged solar cells using lasers, This thesis describes that research, preliminary work performed lasing a representative solar panel array, and a proposed on-orbit experiment to demonstrate the relevant concepts by lasing PAN SAT, an NPS-built and operated spacecraft, The preliminary work done at Maui involved lasing a PAN SAT silicon photovoltaic array using a 975 nm% Yb:YAG source at output power levels of 7 W, 14 W and 21 W, These results matched those obtained under near-AMO conditions atop Mount Haleakala (for the 7 W case) and extrapolated to match predicted output levels, Enough data points were collected at each power level to generate an I-V curve for the panel, identifying the open circuit voltage, short circuit current, and maximum power points, The efficiency of the panel varied from 13,1% (as expected for monochromatic light) at 7 W to 11,3% at 21 W due to uniform heating of the cells, These results represent a "ground truth" baseline from which further research can continue,.
