Electricity generation is one of the largest sources of carbon dioxide production in Canada. The combustion of fossil fuels (coal and natural gas) release carbon dioxide which contributes to rising global temperatures. Wind energy is considered to be an alternative to the traditional methods of generating electricity, producing electricity when the wind blows strong enough to move the turbines but not so strong that the turbines shut down for safety reasons. Although wind energy can be used to produce energy, its production is both variable and uncertain.
When a solar cell is illuminated by light from the sun, a current is generated that can be used to provide electrical power. Conversely, if we apply a current to a solar cell, light is generated and this process is called electroluminescence (EL). In Silicon solar cells the EL is very weak and in a perfect cell is extremely uniform. Defects inherent in the material, such as dislocations which degrade its performance or those created during the cell fabrication process, such as microcracks which affect its long term reliability can be clearly observed in EL imaging.
This internship will numerically simulate the impact of flow structures on power production from river kinetic turbines. These turbines extract renewable energy from rivers from flow velocity rather than from a drop in river levels. To date, a proper mathematical approach of how to place these turbines in a river is not available. Mathematic tools are required to estimate the power reduction when these turbines are subjected to large flow variations in river applications created by river bank profile changes, turbines located upstream, and due to localized changes in the river levels.
Smart Rotor Systems Inc. (SRS) is a new Ottawa-based start-up company, whose product is a novel active control system for the reduction of vibration or noise on rotary wing applications, i.e. on helicopters and wind turbines. Mitigation of vibration and noise is a hot topic in both these sectors nowadays, attracting plenty of attention from both manufacturers and operators. SRS has the competitive edge in owning the Intellectual Property (IP) of the first ever electrically driven Active Pitch Link (APL) as well as for the concept of the control system driving it.
Currently, cellulosic ethanol production is laden with technical challenges, and as a result, not economically viable. The reason for this lies with the toughness of the plant feed material generally called biomass. Processing biomass to allow fermentation to ethanol often requires harsh operations such as extreme heat, pressure, acidity, or a combination of all three. This often leads to the formation of unwanted chemicals that are toxic to organisms that enable fermentation.
In cold climates there is a perception that ice fragments could be thrown from rotating large wind turbines and create a hazard. While turbines should be shut down in icing conditions several authorities now require calculation of the risk associated with this potential hazard, in terms of numbers of ice fragment strikes per unit area per year in areas surrounding a proposed wind farm. As service providers to the wind energy industry, Zephyr North wish to have an accurate, reliable model to provide this information.
The objectives are to determine to what extent a carbon strategy can add to the value of a publicly held Canadian forest products firm, what form that would take, and what conditions would be required to implement. The project will begin with an environmental scan of economic, technological, political]legal, and societal trends that are occurring in the broader context. The focus will then be turned to identify the opportunities available and the company's core competencies (strengths) to take advantage of these opportunities.
Plug-in Hybrid Electric Vehicles are hybrid vehicles with large batteries that are capable of travelling on electricity but still maintain the reliability of an on‐board internal combustion engine for extended trips. The batteries will typically be recharged from a standard household outlet, thus increasing the demand for electricity. It is important to understand and predict how these vehicles will affect the operation and planning of networks in British Columbia.
This research project proposes the exploration of various mechanical systems configured in two residential homes in Milton, Ontario. The primary goal is to determine the energy consumption and monetary costs associated with integrating new technologies of both heating and cooling requirements of a new home. Refinement of previously collected data and software modeling are keys to providing successful long term projections on potential savings in energy usage and economic payback periods.
