EDGE™ Planning Mission Statement: The scope of this project is to design, test and characterize a scaled prototype thermoelectric heat recovery unit for use with Dresser- Rand Turbo Machinery. Objective: This project is aimed at using thermoelectric devices to recover wasted energy exhaust from Dresser Rand VECTRA 40 Gas Turbines. The team will create at least X watt scaled prototype, proof-of-concept heat recovery unit to help educate RIT and Dresser-Rand on sustainable energy systems and technology for remote locations.
EDGE™ Introduction to Thermoelectrics Solid state devices (no moving parts) Two modes of operation 1) Current temperature gradient 2) Power Generation temperature gradient to electrical energy Historically materials in TE modules are off the shelf and have been around since the 1960’s. Advancement in nano-scaled materials in the last 5 years has brought attention to power generation applications.
EDGE™ TE Module Characterization The efficiency of a thermoelectric system is based on the First Law of Thermodynamics and the Carnot Efficiency: Efficiency graph for current and future TE Modules Effect of temperature difference on TE module efficiency

EDGE™ Phase 1: Concept Development Identify Customer Needs - Analysis Identify Potential Issues and Risks The team will most likely find the following issues during the project: Not having enough modules to test early in the design phase of the project Not being able to quantify the output of the modules early on during the project The test stands not functioning properly The test stands are not able to produce the correct situation that the prototype will function in Spending too much of the overall budget on the modules and not having enough to purchase other materials Purchasing the correct modules for the design (wrong materials can create a series problems)
EDGE™ Future Plan Where do you go from here? Determine the tasks for the project in general and then work out the finer points for each task. We then will create a timeline to help create the task lists for each person in the project. This will be done with Microsoft Project. We will have to meet with Dr. Stevens to help define the tasks that will be necessary to complete the project. We then have to update the information on the website to show our most current progress. Also we need to search for potential students with interest and knowledge in the studies of thermo-electrics and other sustainable systems.
