  1. Implementing Thermoelectricity AbdulrahmanFakhroo Gino Rumhein

  2. The Energy Epidemic • Global warming • Fossil fuels are finite • Solutions: • New energy sources • Refine the way we use energy

  3. What is Thermoelectricity? • Thermoelectricity is in essence electric power produced by a temperature gradient • The Seebeck Effect • Inverse of the Peltier Effect

  4. Theory • Kelvin-Planck statement: • Two temperature reservoirs needed • Therefore, 100 percent efficiency is impossible • Our aim: • To recycle Qc

  5. Difficulties • Material that is thermally conductive but not electrically conductive • Seebeck coefficient of material must be high • Seebeck coefficient: • Measure of an induced electric voltage as a result of a temperature difference across a material • A measurement of the thermoelectric efficiency of a material:

  6. Bismuth Telluride • Many thermoelectric properties present • Ideal for refrigeration and portable power generation • High Seebeck coefficient … which comes with a price

  7. Calculations • A calculation of the voltage derived from a temperature difference within a material can be given by: • V(t) • Where S is the Seebeck coefficient given as a function of temperature

  8. Application • Applying the thermo electric effect on daily temperature gradients using Bismuth Telluride, can we recycle the lost heat transfer of various thermodynamic cycles?
