Foam-Based Floatovoltaics: A Potential Solution To Disappearing Terminal Natural Lakes, Koami Soulemane Hayibo, Joshua M. Pearce

Electrical and Computer Engineering Publications

Terminal lakes are disappearing worldwide because of direct and indirect human activities. Floating photovoltaics (FPV) are a synergistic system with increased energy output because of water cooling, while the FPV reduces water evaporation. This study explores how low-cost foam-based floatovoltaic systems can mitigate the disappearance of natural lakes. A case study is performed on 10%–50% FPV coverage of terminal and disappearing Walker Lake. Water conservation is investigated with a modified Penman-Monteith evapotranspiration method and energy generation is calculated with an operating temperature model experimentally determined from foam-based FPV. Results show FPV saves 52,000,000 m3/year of water and US$6,000,000 at 50% …

The Greenest Solar Power? Life Cycle Assessment Of Foam-Based Flexible Floatovoltaics, Koami Soulemane Hayibo, Pierce Mayville, Joshua M. Pearce

Electrical and Computer Engineering Publications

This study presents a life cycle analysis (LCA) of a 10 MW foam-based floatovoltaics (FPV) plant installed on Lake Mead, Nevada, U.S. A material inventory of the flexible crystalline silicon (c-Si)-based module involved massing and determination of material composition of the module's encapsulation layers with ATR/FTR spectroscopy and electron microscopy. The LCA was performed using SimaPro and the results were interpreted in terms of cumulative energy demands, energy payback time, global warming potential, GHG emissions, and water footprint including negative values for reduced evaporation. A sensitivity analysis was performed on the lifetime of the modules and the foam-based racking. The …

NORTHERN TORNADOES PROJECT:

IMPACT AT A GLANCE

Entered into working partnerships with University of Manitoba, York University and The Weather Network

Acquired cutting-edge drone technology, allowing us to obtain high-quality, highly accurate damage survey data and images

Obtained an advanced drone licence, allowing us to fly drones longer distances without keeping the drone in sight

Conducted 409 NTP investigations, 292 Planet satellite surveys, 31 ground surveys, 24 drone surveys and 4 aircraft surveys

Verified the occurrence of 77 tornadoes across Canada in 2020. NTP investigations increased the verified tornado count by 166%

Created a more useful, user-friendly Dashboard and Open …

Commercial Water Claims: City Of London Assessment Of Claims Made By London Residents, Jonathan Abbruzzese, Yousir Aldin, Christine Eagles, Karen Lemon, Alexander Watson

Community Engaged Learning Final Projects

The City of London has a mandate to provide its residents with high grade water and yet there have been complaints concerning the impurities, otherwise known as residuals, and the overall quality. This paper delves into the truth about the contents of the municipal water system and what the effects of its components are to the London populace. A public survey asked residents questions about their concerns and water drinking habits. The survey pointed to concerns about fluoride, residual chlorine and overall taste of water among others. Fluoride is known to reduce tooth decay (CDC, 2018) and any negative consequences …

12 January 2018

The objectives of the Year 1 Pilot Study were to (i) develop a methodology for determining tornado occurrence in Northern Ontario, and (ii) obtain research quality data for at least one event. Because of the isolation of many regions, the approach assumed the use of radar data analysis combined with aerial surveys. These objectives were achieved. Aerial surveys were conducted for …
