Sustainable Cities As The Gateway To The Future: A Case Study Of New Rochelle, Andrea B. Grenadier
Sustainable Cities As The Gateway To The Future: A Case Study Of New Rochelle, Andrea B. Grenadier
Honors Theses
This thesis explores the characteristics of sustainable cities and uses New Rochelle, New York as a case study to further describe initiatives synonymous with green communities. Five prominent topics of sustainable cities and urban planning are discussed within the literature review and later mirrored throughout the case study of New Rochelle. These topics include, smart growth, energy efficiency, green buildings, transportation, and recycling. The mayor of New Rochelle and Sustainability Coordinator completed questionnaires and their responses contributed to an assessment of the contemporary issues facing sustainable cities.
Agricultural Efficiency And The End Of The Oil Age; Building A Future Of Longevity, Keith Mchugh
Agricultural Efficiency And The End Of The Oil Age; Building A Future Of Longevity, Keith Mchugh
Pomona Senior Theses
This thesis uses an efficiency analysis of agricultural systems to assert that, in lieu of rising prices of fossil fuel, people need to come into more direct contact with their food systems. With a switch to smaller, more efficient farms that rely less on fossil fuel and are connected with the communities they supply for, we can avoid an energy crisis turning into a famine. These smaller-scale systems can help create self-contained, carbon-neutral communities.

Innovative Desalination Systems Using Low-Grade Heat, Chennan Li
USF Tampa Graduate Theses and Dissertations
Water and energy crises have forced researchers to seek alternative water and energy sources. Seawater desalination can contribute towards meeting the increasing demand for fresh water using alternative energy sources like low-grade heat. Industrial waste heat, geothermal, solar thermal, could help to ease the energy crisis.
Unfortunately, the efficiency of the conventional power cycle becomes
uneconomically low with low-grade heat sources, while, at the same time, seawater desalination requires more energy than a conventional water treatment process. However, heat discarded from low-grade heat power cycles could be used as part of desalination energy sources with seawater being used as coolant …

Synthesis And Characterization Of Nanocomposites For Electrochemical Capacitors, Farah Alvi
USF Tampa Graduate Theses and Dissertations
Presently there are deep concerns over the environmental consequences and the consumption of non-renewable energy sources, with the accelerated greenhouse effect, triggered enormous interest in the use of renewable energy sources e.g., solar, hydropower, wind and geothermal. However the intermittent nature of harvesting renewable energy sources has recently gained considerable attention in the alternative reliable, cost effective, and environmentally friendly energy storage devices. The supercapacitor and lithium ion batteries are considered more efficient electrical energy storage devices than conventional energy storage systems.
Both devices have many useful and important applications; they could be an excellent source for high power and …

Crack Analysis In Silicon Solar Cells, Maria Ines Echeverria Molina
USF Tampa Graduate Theses and Dissertations
Solar cell business has been very critical and challenging since more efficient and low costs materials are required to decrease the costs and to increase the production yield for the amount of electrical energy converted from the Sun's energy. The silicon-based solar cell has proven to be the most efficient and cost-effective photovoltaic industrial device. However, the production cost of the solar cell increases due to the presence of cracks (internal as well as external) in the silicon wafer. The cracks of the wafer are monitored while fabricating the solar cell but the present monitoring techniques are not sufficient when …
