Thermoelectric materials are formed from compounds from the semi-metal and metal groups of the periodic table. These specific elements are forged together to form a powerful and efficient vector to carry out the thermoelectric effect. We plan to use thermoelectric materials to help convert lost heat from an inefficient internal combustion engine. However, there are different thermoelectric materials and each one has a different capacity and meant for different usage. In order to know what type is best for Clean Currents, our team has used the figure of merit (ZT). A ZT value signifies the efficiency a thermoelectric material can convert heat to energy. Albeit this industry is very young and developing, it can have enormous and vast applications. This is highlighted through the Carnot's Theorem. This theory considers the notion that the limit of the conversion rate between energy and heat and that efficiency approaches to infinity. Essentially, this means that eventually we will be able to completely convert every ounce of heat into electricity. Current technology allows a conversion rate of 25%. This value is projected to increase for the years to come; Clean Currents will improve for the years to come as well. Clearly, the future for Clean Currents is smoothly paved! |
Thermoelectric Effect: Utilizing temperature change to create electrical potential or vise versa. Carnot's Theorem: This theory states that there is no upper bound for ZT values. |
