This proposal aims to research and optimize thermoelectric alloys for the efficient generation of thermoelectricity. The central focus of the proposal is the design and fabrication of thermoelectric generators (TEGs) to be incorporated in oil and natural gas home heating systems, which will render them autonomous under electricity power outages. TEGs are capable of collecting part of the thermal energy of the exhaust gases of a heating system at the rather low temperatures (around 100 C) necessary to optimize the overall efficiency of such system. The implementation of an efficient and autonomous heating system based on TEGs would provide a solution to a currently unsafe situation facing all Canadians, with the added bonus of providing energy savings which will be significant in terms of the thermal energy that can still potentially be recovered. Due to the excellent (already tested) mechanical properties of extruded thermoelectric alloys which we obtained in the past for cooling applications, we  foresee that adequate alloys can be found and processed in order to produce modules with extremely short legs (about a factor of 4 smaller that what has been achieved in practice so far). This unique advantage, while keeping excellent thermoelectric properties and a very low cost, enables us to predict the feasibility of efficient, practical modules with a reasonably small area which will provide in excess of 200W output energy to run heating systems without the requirement of the electric grid.

该建议旨在研究和优化热电合金，以有效地产生热电学。该提案的重点是将热电发电机（TEG）的设计和制造纳入油气和天然气家庭供暖系统中，这将使它们在电力电力中断下使它们具有自主性。 TEG能够在相当低的温度（约100 C）处收集加热系统排气系统的热能，以优化此类系统的整体效率。基于TEG的高效和自主加热系统的实施将为所有加拿大人面临的当前不安全情况提供解决方案，并提供了提供节能的额外奖励，这些节能在仍然可以回收的热能方面将非常重要。由于我们过去为冷却应用获得的挤压热电合金具有出色的（已经测试过的）机械性能，因此我们预计可以找到并处理足够的合金，并处理具有非常短的腿部的模块（大约是4个较小的4个较小的一个较小的较小的，这是在迄今为止实现的实践）。这种独特的优势，同时保持出色的热电特性和非常低的成本，使我们能够预测具有相当小的面积的高效，实用模块的可行性，该模块将提供超过200W的输出能量以运行加热系统，而无需电网。
