Design, Construction And Evaluation Of A Multi Layered Solar Distillation Prototype, Arlen A. Flanagan
BioResource and Agricultural Engineering
Water is arguably the most important resource to any individual; especially in areas of deserts and open oceans where drinkable water suppliers are scarce. The prototype Solar Desalination Unit allows normally undrinkable water to be distilled into a potable source with minimal inputs. The unit’s main power source is focused sunlight to thermally heat water inducing evaporation which is then condensed and collected. While solar desalination has been around for many years, lately more complex designs have been investigated in order to increase yields and efficiency. This paper focuses on the design, construction and testing of a Multi-Plate Solar Desalination …

ABSTRACT
Multidisciplinary Design Optimization of an Extreme Aspect Ratio HALE UAV
Bryan J. Morrisey
Development of High Altitude Long Endurance (HALE) aircraft systems is part of a vision for a low cost communications/surveillance capability. Applications of a multi payload aircraft operating for extended periods at stratospheric altitudes span military and civil genres and support battlefield operations, communications, atmospheric or agricultural monitoring, surveillance, and other disciplines that may currently require satellite-based infrastructure. Presently, several development efforts are underway in this field, including a project sponsored by DARPA that aims at producing an aircraft that can sustain flight for multiple years and …

Doctoral Dissertations 1896 - February 2014
In order to meet the demands of the continuous scaling of electronic devices, new technologies have been developed over the years. As we approach the newest levels of miniaturization, current technologies, such as physical vapor deposition and chemical vapor deposition, are reaching a limitation in their ability to successfully fabricate nano sized electronic devices.
Supercritical fluid deposition (SFD) is a demonstrated technology that provides excellent step coverage for the deposition of metals and metal oxides within narrow, high aspect ratio features. This technique shows the potential to satisfy the demands of integrated circuit miniaturization while maintaining a cost effective process …
Production And Storage Of Hydrogen, Michael Muller
Production And Storage Of Hydrogen, Michael Muller
Masters
The Faculty of Electrical Engineering and Information Technology at the University of Applied Science in Darmstadt runs several hydrogen-related experiments at their fuel cell laboratory. In cooperation with the Technological University Dublin (DIT), a new project was started in 2007. The aim of this project was to develop an energy storage system, which would work with hydrogen as a high quality energy storage. This system was developed for using the electricity of solar panels in order to run an electrolyser. Hydrogen is produced and afterwards stored in an adequate storage tank. Once the hydrogen has been stored, it can be …

A novel photovoltaic dipole antenna employing a solar concentrator as a reflector is proposed. Four identical emitter-wrap-through rear contact solar cells connected in series as a folded dipole are simultaneously used for power generation and as the antenna radiating element, which is located in the focal line of a parabolic solar concentrator. The parabolic structure acts as a solar concentrator for the photovoltaic cells as well as a reflector for the folded dipole antenna. Full-wave electromagnetic simulation with supportive experimental work validates this design. The measured fractional impedance bandwidth and gain were 21% and 11.1 dBi, respectively. The antenna/solar arrangement …
Alternative Sources Of Energy, David Kennedy
Alternative Sources Of Energy, David Kennedy
Conference Papers
Ireland relies on imports of fossil fuels for up to 83% of its energy needs and this statistic is relatively common in other European countries. Apart from the high import costs and pollutions associated with fossil fuels and the need to meet new targets in terms of CO2 emissions, energy security is essential. This paper provides an overview and outline of the different alternative energy sources available for use either at domestic or on large scale production, some of which are established and others less likely to succeed in our climate.
Some of the alternative energy sources such as wind …
