Silicon-on ceramic process. Silicon sheet growth and device developmentt for the Large-Area Silicon Sheet Task of the Low-Cost Solar Array Project. Quarterly report No. 13, October 1-December 31, 1979
Research on the technical and economic feasibility of producing solar-cell-quality sheet silicon by coating inexpensive ceramic substrates with a thin layer of polycrystalline silicon is reported. The coating methods to be developed are directed toward a minimum-cost process for producing solar cells with a terrestrial conversion efficiency of 11 percent or greater. By applying a graphite coating to one face of a ceramic substrate, molten silicon can be caused to wet only that graphite-coated face and produce uniform thin layers of large-grain polycrystalline silicon; thus, only a minimal quantity of silicon is consumed. A variety of ceramic materials have been dip coated with silicon. The investigation has shown that mullite substrates containing an excess of SiO/sub 2/ best match the thermal expansion coefficient of silicon and hence produce the best SOC layers. With such substrates, smooth and uniform silicon layers 25 cm/sup 2/ in area have been achieved with single-crystal grains as large as 4 mm in width and several cm in length. Crystal length is limited by the length of the substrate. The thickness of the coating and the size of the crystalline grains are controlled by the temperature of the melt and the rate at which the substrate …

Cost of Czochralski wafers as a function of diameter
The impact of diameter in the range of 10 to 15 cm on the cost of wafers sliced from Czochralski ingots is analyzed. Increasing silicon waste and decreasing ingot cost with increasing ingot size are estimated along with projected costs. Results indicate a small but continuous decrease in sheet cost with increasing ingot size in this size range. Sheet costs including silicon are projected to be $50 to $60/m/sup 2/ (1980 $) depending upon technique used.

Demonstration of innovative applications of technology for cost reductions to the CT-121 FGD process
The objective of this project is to demonstrate on a commercial scale several innovative applications of cost-reducing technology to the Chiyoda Thoroughbred-121 (CT-121) process. CT-121 is a second generation flue gas desulfurization (FGD) process which is considered by the Electric Power Research Institute (EPRI) and Southern Company Services (SCS) to be one of the most reliable and lowest cost FGD options for high-sulfur coal-fired utility boiler applications. Demonstrations of the innovative design approaches will further reduce the cost and provide a clear advantage to CT121 relative to competing technology.

CONC/11: a computer program for calculating the performance of dish-type solar thermal collectors and power systems
CONC/11 is a computer program designed for calculating the performance of dish-type solar thermal collectors and power systems. It is intended to aid the system or collector designer in evaluating the performance to be expected with possible design alternatives. From design or test data on the characteristics of the various subsystems, CONC/11 calculates the efficiencies of the collector and the overall power system as functions of the receiver temperature for a specified insolation. If desired, CONC/11 will also determine the receiver aperture and the receiver temperature that will provide the highest efficiencies at a given insolation. The program handles both simple and compound concentrators. CONC/11 is written in Athena Extended Fortran (similar to Fortran 77) to operate primarily in an interactive mode on a Sperry 1100/81 computer. It could also be used on many small computers.

Health and safety evaluation of a modified tunnel-borer design for application to single-entry coal-mine development
The health and safety analysis is part of an overall effort to identify and develop innovative underground coal extraction systems. The single-entry tunnel borer system was initially considered an innovative approach to underground mining because it exhibited a means of increasing the speed and efficiency of entry development by reducing the number of entries. However, to be considered a truly advanced system, the tunnel borer had to meet distinct safety criteria as well. The objective was to examine the tunnel borer design and determine whether it offset major health hazards, and satisfied the prescribed safety levels. As a baseline for comparison, the tunnel borer was compared against the continuous mining entry driving system. The results of the health analysis indicated that while the tunnel borer design offered improvements in dust control through the use of water sprays, a higher face ventilation rate, and the application of spalling rather than the conventional grinding process, it interjected an additional mutagenic is and toxic compound into the environment through the use of shotcrete. The tunnel borer system easily conformed with the prescribed fatality limit, but exceeded the required limits for disabling and overall injuries. It also exhibited projected disabling and overall injury rates …

Medicare Physician Payment: Care Coordination Programs Used in Demonstration Show Promise, but Wider Use of Payment Approach May Be Limited
A letter report issued by the Government Accountability Office with an abstract that begins "Congress mandated in 2000 that the Centers for Medicare & Medicaid Services (CMS) conduct the Physician Group Practice (PGP) Demonstration to test a hybrid payment methodology for physician groups that combines Medicare fee-for-service payments with new incentive payments. The 10 participants, with 200 or more physicians each, may earn annual bonus incentive payments by achieving cost savings and meeting quality targets set by CMS in the demonstration that began in April 2005. In July 2007, CMS reported that in the first performance year (PY1), 2 participants earned combined bonuses of approximately $7.4 million, and all 10 achieved most of the quality targets. Congress mandated that GAO evaluate the demonstration. GAO examined, for PY1, the programs used, whether the design was reasonable, and the potential challenges in broadening the payment approach used in the demonstration to other physician groups. To do so, GAO reviewed CMS documents, surveyed all 10 groups, and conducted interviews and site visits."

Regulatory Review: Delay of Effective Dates of Final Rules Subject to Administration's January 20, 2001, Memorandum
Correspondence issued by the General Accounting Office with an abstract that begins "Citing the desire to "ensure that the President's appointees have the opportunity to review any new or pending regulations," the White House Chief of Staff Andrew H. Card, Jr. sent a memorandum to the heads of all executive agencies on January 20, 2001, directing them to (1) not send proposed or final regulations to the Office of the Federal Register, (2) withdraw regulations that had been sent to the Office but not yet published in the Federal Register, and (3) postpone for 60 days the effective date of regulations that had been published in the Federal Register but had not yet taken effect. GAO found that federal agencies delayed the effective dates for 90 of the 371 final rules that were subject to the memorandum. The effective dates for the remaining 281 rules were either not delayed or GAO could find no indication in the Federal Register of a delay."

Pipeline Permitting: Interstate and Intrastate Natural Gas Permitting Processes Include Multiple Steps, and Time Frames Vary
A letter report issued by the Government Accountability Office with an abstract that begins "Both the interstate and intrastate natural gas pipeline permitting processes are complex and can involve multiple federal, state, and local agencies, as well as public interest groups and citizens, and include multiple steps. The interstate process involves a voluntary pre-filing phase, an application phase, and a post-authorization phase with multiple steps that stakeholders reported to be consistent among projects because the process is led by the Federal Energy Regulatory Commission (FERC). FERC coordinates with federal, state, and local agencies that have statutory and regulatory authority over various environmental laws and regulations. For example, if a proposed pipeline may affect endangered species, FERC coordinates with the U.S. Fish and Wildlife Service, which reviews the impacts on such species. The intrastate process can also involve multiple stakeholders and steps, but, unlike in the interstate process, GAO found that the stakeholders and steps vary by state. For example, of the 11 states GAO reviewed, 5 have agencies charged with approving the route of natural gas pipelines and require advance approval of the location and route, and the remaining 6 do not. Pipeline companies must also comply with various federal …

Law Enforcement Body Armor: DOJ Supports Its Use and Enhancements, but Could Strengthen Management of Its Related Grant Programs
Testimony issued by the Government Accountability Office with an abstract that begins "DOJ has a number of initiatives to support body armor use by state and local law enforcement, including grant funding, research, standards development, and testing programs. Two separate BJA grant programs provide funding to state and local law enforcement to facilitate their body armor purchases. The BVP program offers 2-year grants on a reimbursable, matching basis to state and local law enforcement agencies to assist in their purchasing of ballistic-resistant and stab-resistant body armor. Generally, the JAG program provides 4-year grant money up front that can be used to fund body armor procurement along with other criminal justice activities. Since the BVP programs inception in 1999, it has reimbursed grantees $247 million for their purchases of nearly 1 million vests. The JAG program has provided nearly $4 billion from fiscal years 2006 through 2011, but BJA does not know how much of this amount grantees have spent on body armor because it is not required to track expenditures for specific purposes. Instead, BJA reports that from fiscal years 2006 through 2011, 357 grantees intended to use JAG funds for ballistic-resistant vest procurement, but it does not track how …

Health Care Spending: Public Payers Face Burden of Entitlement Program Growth, While All Payers Face Rising Prices and Increasing Use of Services
Testimony issued by the Government Accountability Office with an abstract that begins "GAO testified about the challenges involved in financing health care. GAO has been particularly concerned about the federal government's long-term fiscal sustainability and the contribution of health care spending to this troubling picture. For the past several years, we have consistently reported that in just a few decades, the government will face a serious fiscal imbalance driven by known demographic trends and escalating health care cost growth. Over the next several decades, growth in spending on federal retirement and health entitlements will encumber an escalating share of the government's resources. These entitlement programs primarily include Social Security, which provides, among other things, retirement income to individuals aged 62 and older; Medicare, which provides health care coverage primarily for individuals 65 and older; and Medicaid, which is a joint federal-state program providing health care and long-term care for low-income individuals. Congress's concern about the challenges involved in financing health care is consistent with the fact that certain spending pressures faced by Medicare and Medicaid are faced by all health care payers, including the Departments of Veterans Affairs (VA) and Defense, as well as private payers of health care.

Unmanned Aircraft Systems: Continued Coordination, Operational Data, and Performance Standards Needed to Guide Research and Development
Testimony issued by the Government Accountability Office with an abstract that begins "While Congress has tasked FAA to lead the effort of safely integrating unmanned aircraft systems (UAS) in the national airspace, several federal and other entities also have a role. FAA has established various mechanisms to facilitate collaboration with these entities. For example, FAA has entered into formal agreements with the Department of Defense (DOD) and the National Aeronautics and Space Administration (NASA) on obtaining appropriate safety data and coordinating research and development, respectively. FAA has also involved industry stakeholders and academia in the development of standards and research for UAS operations. FAA recently created the UAS Integration Office, within FAA, to coordinate all intra-agency UAS efforts and provide organizational leadership. Continued collaboration among UAS stakeholders will be critical to minimizing duplication of research and addressing implementation obstacles."

Contract Management: The Air Force Should Improve How It Purchases AWACS Spare Parts
A letter report issued by the Government Accountability Office with an abstract that begins "Over the past several years, the Air Force has negotiated and awarded more than $23 million in contracts to the Boeing Corporation for the purchase of certain spare parts for its Airborne Warning and Control System (AWACS) aircraft. Since they first became operational in March 1977, AWACS aircraft have provided U.S. and allied defense forces with the ability to detect, identify, and track airborne threats. In March 2003, GAO received allegations that the Air Force was overpaying Boeing for AWACS spare parts. This report provides the findings of GAO's review into these allegations. Specifically, GAO identified spare parts price increases and determined whether the Air Force obtained and evaluated sufficient information to ensure the prices were fair and reasonable. GAO also determined the extent to which competition was used to purchase the spare parts."

Tax Policy: Tax-Exempt Status of Certain Bonds Merits Reconsideration, and Apparent Noncompliance with Issuance Cost Limitations Should Be Addressed
A letter report issued by the Government Accountability Office with an abstract that begins "The outstanding amount of state and local government tax-exempt bonds has increased over the years. Congress is interested in whether the bonds are used for appropriate purposes since the federal government forgoes billions in tax revenues annually by excluding the bonds' interest from investors' federal gross income. Questions also exist over the bonds' borrowing costs as they can divert funds from the funded projects. This report (1) describes recent trends in tax exempt bonds, (2) provides information on the types of facilities financed with tax-exempt bonds, and (3) discusses borrowing costs considering the methods of selling bonds and compares issuance costs paid from bond proceeds for governmental and qualified private activity bonds. In addition to interviewing relevant officials, we analyzed IRS's Statistics of Income (SOI) data and data from Thomson Financial to address these objectives."

Endangered Species Act: Fee-Based Mitigation Arrangements
Correspondence issued by the General Accounting Office with an abstract that begins "The Endangered Species Act seeks to protect affected species and their habitats from the activities of federal agencies and individual landowners. If a landowner plans to engage in an activity that may harm endangered species or their habitats, the landowner may prepare a Habitat Conservation Plan that may include paying a fee to a third party to ensure that the affected species is protected. GAO reviewed (1) the various types of fee-based mitigation arrangements currently used by the Fish and Wildlife Service, (2) who selects the alternative used to mitigate adverse impacts, (3) the Service's role in setting fees and land exchange ratios, and (4) how the Service ensures that fees are used as intended and that desired mitigation results are achieved. GAO found that (1) eight types of fee-based arrangements are now at the locations GAO visited, seven of which require the landowner to act; (2) the landowner is ultimately responsible for deciding whether to use a fee-based mitigation arrangement after considering its advantages and disadvantages; (3) the Service's level of involvement in setting fees and establishing land exchange ratios varies by project and type of arrangement; …
