Portable, Linear-Focused Solar Thermal Energy Collecting System, James C. Fletcher, Charles G. Miller, Jens G. Pohl
Portable, Linear-Focused Solar Thermal Energy Collecting System, James C. Fletcher, Charles G. Miller, Jens G. Pohl
Architecture
A solar heat collection system is provided by utilizing a line-focusing device that is effectively a cylindrically curved concentrator within a protected environment formed by a transparent inflatable casing. A target, such as a fluid or gas carrying conduit is positioned within or near the casing containing the concentrator, at the line focus of the concentrator. The casing can be inflated at the site of use by a low pressure air supply to form a unitary light-weight structure. When deflated, the collector, including casing, concentrator and target, is readily transportable. A system constructed from a plurality of such line-focusing devices …
Three-Dimensional Tracking Solar Energy Concentrator And Method For Making Same, James C. Fletcher, Charles G. Miller, Jens G. Pohl
Three-Dimensional Tracking Solar Energy Concentrator And Method For Making Same, James C. Fletcher, Charles G. Miller, Jens G. Pohl
Architecture
A tracking three-dimensional solar energy concentrator is provided by a stretched aluminized polymeric membrane supported by a hoop, the polymeric membrane being formed to a desired curvature by differential loading. The loading on the polymeric membrane determines its curvature. The loading can be varied by utilizing a plastic membrane that has a non-uniform radial distribution of thickness with uniform differential pressure or by applying a non-uniform differential pressure on a membrane having uniform thickness. Reflector membranes having a non-uniform radial distribution of thickness can be obtained by selective spraying of a dissolved plastic such as Krylon on the underside of …
Waste Reduction: Issues And Policies, W. David Conn
Waste Reduction: Issues And Policies, W. David Conn
City and Regional Planning
This paper reviews the major problems that confronted the Committee set up by the Solid Waste Management Board of the state of California to prepare a background report and recommend alternative methods for reducing solid waste generation. The results of their analysis are presented, together with discussion of the conclusions reached.
The Uses Of Completed Landfills, Jo Anne H. Aplet, W. David Conn
The Uses Of Completed Landfills, Jo Anne H. Aplet, W. David Conn
City and Regional Planning
Completed landfills can provide the base for parks and other beneficial land uses, thus serving to recycle waste products into new forms. However, the conversion is not trouble-free. This paper examines some of the uses to which completed landfills have been put as well as the problems which have been encountered to date, and suggests actions which planners and solid waste managers can take to mitigate some of these problems in the future. Information is based largely on experiences in Los Angeles County, California, where landfilling has been both practised and studied over an extended period.
