The WIMP Forest: Indirect Detection of a Chiral Square
The spectrum of photons arising from WIMP annihilation carries a detailed imprint of the structure of the dark sector. In particular, loop-level annihilations into a photon and another boson can in principle lead to a series of lines (a WIMP forest) at energies up to the WIMP mass. A specific model which illustrates this feature nicely is a theory of two universal extra dimensions compactified on a chiral square. Aside from the continuum emission, which is a generic prediction of most dark matter candidates, we find a 'forest' of prominent annihilation lines that, after convolution with the angular resolution of current experiments, leads to a distinctive (2-bump plus continuum) spectrum, which may be visible in the near future with the Fermi Gamma-Ray Space Telescope (formerly known as GLAST).

Wind Issues in Solar Thermal Performance Ratings: Preprint
We suggest that wind bias against unglazed solar water heaters be mitigated by using a calibrated collector model to derive a wind correction to the measured efficiency curve.

Wind Powering America - Outreach in Priority States (Poster)
WPA works with 33 State Wind Working Groups to educate stakeholders on wind energy topics and to achieve the basics needed for effective wind development in a state. WPA has accelerated outreach and communication efforts with 13 priority states: Alaska, Arizona, Indiana, Maryland, Massachussetts, Michigan, Nebraska, Nevada, North Carolina, Ohio, South Dakota, Utah, and Virginia. These states have the potential to contribute substantially to the national portfolio of wind energy but do not yet have large amounts of wind energy applications on the ground. This is often due to barriers in in-state knowledge and understanding of wind energy issues and potential that impact the policy environment and the market environment. There are common regional issues among the states, and important learning opportunities can be gained by cross-training and sharing experiences. The Regional Wind Energy Institutes (RWEIs) are train-the-trainer organizations that work to develop a cadre of in-state outreach specialists who reach out to audiences of decisionmakers (e.g., the ag community, state and local officials, utilities, regulatory bodies) to build understanding, create public acceptance, take advantage of regional synergies, and eventually to impact polices and the market environment for effective wind implementation.

Workforce Development: A Survey of Industry Needs and Training Approaches
This paper presents information and data collected during 2008 on PV workforce needs by the Interstate Renewable Energy Council for the U.S. Department of Energy. The data was collected from licensed contractors, PV practitioners, educators and expert instructors at training sessions, and at focus group and advisory committee meetings. Respondents were primarily from three states: Florida, New York and California. Other states were represented, but to a lesser extent. For data collection, a 12-item questionnaire was developed that addressed key workforce development issues from the perspectives of both the PV industry and training institutions. A total of 63 responses were collected, although not every respondent answered every question. Industry representatives slightly outnumbered the educators, although the difference in responses was not significant.

Basin-Scale Hydrologic Impacts of CO2 Storage: Regulatory and Capacity Implications
Industrial-scale injection of CO{sub 2} into saline sedimentary basins will cause large-scale fluid pressurization and migration of native brines, which may affect valuable groundwater resources overlying the deep sequestration reservoirs. In this paper, we discuss how such basin-scale hydrologic impacts can (1) affect regulation of CO{sub 2} storage projects and (2) may reduce current storage capacity estimates. Our assessment arises from a hypothetical future carbon sequestration scenario in the Illinois Basin, which involves twenty individual CO{sub 2} storage projects in a core injection area suitable for long-term storage. Each project is assumed to inject five million tonnes of CO{sub 2} per year for 50 years. A regional-scale three-dimensional simulation model was developed for the Illinois Basin that captures both the local-scale CO{sub 2}-brine flow processes and the large-scale groundwater flow patterns in response to CO{sub 2} storage. The far-field pressure buildup predicted for this selected sequestration scenario suggests that (1) the area that needs to be characterized in a permitting process may comprise a very large region within the basin if reservoir pressurization is considered, and (2) permits cannot be granted on a single-site basis alone because the near- and far-field hydrologic response may be affected by interference between individual …
