PV energy program overview FY 1998

Description: In this overview, the goals that were met in FY 1998 are highlighted along with progress that was made toward long-term goals for research, technology development, and applications. The manufacture, sale, and use of photovoltaic (PV) devices to generate electricity directly from sunlight has become a billion-dollar industry worldwide. The production capacity for PV modules in the US had doubled between 1993 and 1997. While continuing research to improve technology, one must work with industry to move this technology from the laboratory to the marketplace.

Alternative Fuel News, Vol. 2, No. 6

Description: The cover story in this issue of the Alternative Fuel News highlights the niche market principle; the places in which AFVs would best fit. This year's SEP funding is expected to be the springboard needed for the development of niche projects. The Clean Cities Program, by matching those needs and attributes in niches, can dramatically increase the attractiveness of AFVs and make an impact on those high-mileage, high-use fleets.

On the Path to Zero Energy Homes

Description: Just imagine living in Florida and your fantasies might turn to swaying palms, fresh orange juice and lots of air-conditioning. For most people, a summer spent in Florida's heat and humidity would be unbearable without it. So air-conditioning is a necessity. But it's also a big energy drain, accounting for about 35% of all electricity used in a typical Florida house. As the largest single source of energy consumption in Florida, a home's air-conditioning load represents the biggest energy challenge. The Florida Solar Energy Center (FSEC) designed a project to answer this challenge. Two homes were built with the same floor plan on near-by lots. The difference was that one (the ''control home'') conformed to local residential building practices, and the other (the ''Zero Energy home'') was designed with energy efficiency in mind and solar technology systems on the roof. The homes were then monitored carefully for energy use. The project's designers were looking to answer two important questions: Could a home in a climate such as central Florida's be engineered and built so efficiently that a relatively small PV system would serve the majority of its cooling needs--and even some of its daytime electrical needs? And, would that home be as comfortable and appealing as the conventional model built alongside it? The answer to both questions turned out to be a resounding yes. And the test was especially rigorous, because it was conducted in the summer of 1998--one of the hottest summers on record in Florida. This news is important for city planners, architects, builders, and homeowners not only in the Sunshine State, but elsewhere, too. The solar/energy efficiency combo worked so well in Florida that it can--and should--be tried in other parts of the country. This brochure describes the Zero Energy Homes concept using a case study.

Description: Single-crystal neutron diffraction measures the elastic Bragg reflection intensities from crystals of a material, the structure of which is the subject of investigation. A single crystal is placed in a beam of neutrons produced at a nuclear reactor or at a proton accelerator-based spallation source. Single-crystal diffraction measurements are commonly made at thermal neutron beam energies, which correspond to neutron wavelengths in the neighborhood of 1 Angstrom. For high-resolution studies requiring shorter wavelengths (ca. 0.3-0.8 Angstroms), a pulsed spallation source or a high-temperature moderator (a ''hot source'') at a reactor may be used. When complex structures with large unit-cell repeats are under investigation, as is the case in structural biology, a cryogenic-temperature moderator (a ''cold source'') may be employed to obtain longer neutron wavelengths (ca. 4-10 Angstroms). A single-crystal neutron diffraction analysis will determine the crystal structure of the material, typically including its unit cell and space group, the positions of the atomic nuclei and their mean-square displacements, and relevant site occupancies. Because the neutron possesses a magnetic moment, the magnetic structure of the material can be determined as well, from the magnetic contribution to the Bragg intensities. This latter aspect falls beyond the scope of the present unit; for information on magnetic scattering of neutrons see Unit 14.3. Instruments for single-crystal diffraction (single-crystal diffractometers or SCDs) are generally available at the major neutron scattering center facilities. Beam time on many of these instruments is available through a proposal mechanism. A listing of neutron SCD instruments and their corresponding facility contacts is included in an appendix accompanying this unit.
