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."

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 …

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."

Defense Logistics: Improved Oversight and Increased Coordination Needed to Ensure Viability of the Army's Prepositioning Strategy
A letter report issued by the Government Accountability Office with an abstract that begins "Prepositioned military equipment and supplies on ships and overseas on land have become an integral part of the U.S. defense strategy. However, the Army's program has faced long-standing management challenges, including equipment excesses and shortfalls, invalid or poorly defined requirements, and maintenance problems. In Public Law 109-163, Congress required the Army to conduct an assessment of its prepositioning programs and required GAO to assess (1) whether the Army's report addressed the areas required by Congress, and (2) the major challenges the Army continues to face in its prepositioning program. GAO analyzed the Army's report and other information it obtained from the Joint Staff, the Army, and its subordinate commands to identify the issues affecting the Army's prepositioning program. GAO also visited prepositioned equipment sites in South Carolina, Europe, South Korea, and Kuwait."

Climate Change Issues: Options for Addressing Challenges to Carbon Offset Quality
A letter report issued by the Government Accountability Office with an abstract that begins "Carbon offsets are reductions in greenhouse gas emissions in one place to compensate for emissions elsewhere. Examples of offset projects include planting trees, developing renewable energy sources, or capturing emissions from landfills. Recent congressional proposals would have limited emissions from utilities, industries, or other "regulated entities," and allowed these entities to buy offsets. Research suggests that offsets can significantly lower the cost of a program to limit emissions because buying offsets may cost regulated entities less than making the reductions themselves. Some existing international and U.S. regional programs allow offsets to be used for compliance with emissions limits. A number of voluntary offset programs also exist, where buyers do not face legal requirements but may buy offsets for other reasons. Prior GAO work found that it can be difficult to ensure offset quality--that offsets achieve intended reductions. One quality criterion is that reductions must be "additional" to what would have occurred without the offset program. This report provides information on (1) key challenges in assessing the quality of different types of offsets and (2) options for addressing key challenges associated with offset quality if the U.S. …

Law Enforcement Body Armor: DOJ Could Enhance Grant Management Controls and Better Ensure Consistency in Grant Program Requirements
A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Justice (DOJ) has a number of initiatives to support body armor use by state and local law enforcement, including funding, research, standards development, and testing programs. Two Bureau of Justice Assistance (BJA) grant programs provide funding to state and local law enforcement to facilitate their body armor purchases. The Bulletproof Vest Partnership (BVP) program offers 2-year grants on a reimbursable basis. The Edward Byrne Memorial Justice Assistance Grant (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 about $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. 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 many grantees intended …

Deposit Insurance: Assessment of Regulators' Use of Prompt Corrective Action Provisions and FDIC's New Deposit Insurance System
A letter report issued by the Government Accountability Office with an abstract that begins "The Federal Deposit Insurance Reform Conforming Amendments Act of 2005 required GAO to report on the federal banking regulators' administration of the prompt corrective action (PCA) program under section 38 of the Federal Deposit Insurance Act (FDIA). Congress created section 38 as well as section 39, which required regulators to prescribe safety and soundness standards related to noncapital criteria, to address weaknesses in regulatory oversight during the bank and thrift crisis of the 1980s that contributed to deposit insurance losses. The 2005 act also required GAO to report on changes to the Federal Deposit Insurance Corporation's (FDIC) deposit insurance system. This report (1) examines how regulators have used PCA to resolve capital adequacy issues at depository institutions, (2) assesses the extent to which regulators have used noncapital supervisory actions under sections 38 and 39, and (3) describes how recent changes to FDIC's deposit insurance system affect the determination of institutions' insurance premiums. GAO reviewed regulators' PCA procedures and actions taken on a sample of undercapitalized institutions. GAO also reviewed the final rule on changes to the insurance system and comments from industry and academic experts."

Vehicle Donations: Selected Charities Reported Mixed Experiences after Changes in Vehicle Donation Rules
A letter report issued by the Government Accountability Office with an abstract that begins "In 2003, GAO found that many taxpayers' estimates of the value of their vehicles, claimed as tax deductions, were in excess of the charities' subsequent sales of the vehicles. Subsequently, effective January 1, 2005, the rules related to the amount taxpayers can claim as a deduction on their tax returns for vehicles donated to charities changed. Under the new rules, in many cases the amount taxpayers are allowed to claim as a deduction is less than they could have claimed before the changes. Some charities that used vehicle donations as a revenue source said that the changes could lead to fewer donated vehicles and reduced revenues. GAO was asked to determine how charities have been affected by the 2005 changes. GAO discussed the rule changes with Internal Revenue Service (IRS) officials and the impact of the changes with representatives of several charities. GAO judgmentally selected 10 charities from among the 65 contacted in the course of the 2003 GAO study. The experiences of these charities cannot be generalized to all charities because the selected charities were not drawn from a statistical sample of all charities with …
