Saturable-reactor motor starter reduces line voltage fluctuations
Saturable reactor starter uses back electromotive force /emf/ generated by large motors /18,650 to 596,800 watts/ to limit and control the starting current
Wideband, high efficiency optical modulator requires less than 10 watts drive power
Wideband optical modulation system operates with less than 10-watts drive power. It consists of an optical modulator and transistorized driver that combines small cross-section potassium dideuterium phosphate crystals with laser beam-condensing optics. Optical modulation systems may serve importantly in future space wideband communication systems
Radioisotope thermal photovoltaic application of the GaSb solar cell
An examination of a RTVP (radioisotopic thermophotovoltaic) conceptual design has shown a high potential for power densities well above those achievable with radioisotopic thermoelectric generator (RTG) systems. An efficiency of 14.4 percent and system specific power of 9.25 watts/kg were predicted for a system with sixteen GPHS (general purpose heat source) sources operating at 1100 C. The models also showed a 500 watt system power by the strontium-90 isotope at 1200 C at an efficiency of 17.0 percent and a system specific power of 11.8 watts/kg. The key to this level of performance is a high-quality photovoltaic cell with narrow bandgap and a reflective rear contact. Recent work at Boeing on GaSb cells and transparent back GaAs cells indicate that such a cell is well within reach

The Gospel, Reinvented: A New Addition to the Jesus of Alan Watts
The purpose of this thesis is to analyze and expand the ideas of one of the most widely acclaimed religious thinkers of the twentieth century, Alan Watts. Watts attempted to use Eastern religions as a lens for reinterpreting the message of Jesus\u27s gospel. Watts proposed that Jesus\u27s experience of consciousness was not unique unto himself; furthermore, he asserted that any person can achieve Jesus\u27s level of divinity once he understands that everything, oneself included, is a manifestation of God. To further Watt\u27s claim I bring in an ancient Christian source which was unavailable to Watts during his lifetime-the Gospel of Thomas
