  1. Design for a Practical Green Energy Education John Mativo and Steven Griffing University of Georgia ITEEA 2010: Charlotte, NC

  2. Why Energy Concerns • Air quality and energy issues • Personal expenditure (high cost) • Political motives

  3. Energy and its forms • Power – permeates through all things • Ability to do work • Kinetic and potential • In the form of • Chemical, Electrical, Gravitational, Heat (thermal), Light (radiant), Motion (kinetic), Nuclear • Renewable and non renewable

  4. Renewable Energy • Solar • Geothermal • Biomass • Wind • Hydropower

  5. Non renewable energy • Fossil fuels • Oil • Natural gas • coal

  6. Renewable energy role

  7. Design for a Practical Green Energy Education • Solar • Biomass • Fuel cell

  8. Practical Solar What’s for dinner? Solar sausage...of course. Three minutes under the sun and it was over 180* 200* and rising slowly as the stone heats up.   All of this after 4:00 PM in the afternoon. Not bad for a saran wrap window using window shade slats for a frame. The box is foil lined 2" Styrofoam (expanded polystyrene beads). Next project is to line the satellite dish with Mylar and ZAP some hot dogs.

  9. Useful energy

  11. Fuel Cells • A factory – fuel as input and electricity as product • Fuel – oxygen and hydrogen • Product electricity and water http://en.wikipedia.org/wiki/File:Fuel_Cell_Block_Diagram.png

  12. Fuel Cells Types • Phosphoric acid fuel cell (PAFC) • 200C, platinum, H+ • Polymer electrolyte membrane fuel cell (PEMFC) • 80C, platinum, H+ • Alkaline fuel cell (AFC) • 60 -220C, platinum, OH+ • Molten carbonate fuel cell (MCFC) • 650C, Nickel, • Solid-oxide fuel cell (SOFC) • 600-1000C, Perovskites (ceramic), O2-

  13. Fuel Cell Challenges • Membrane issues • Remove water from anode/cathode • Expensive catalyst • Corrosive catalyst • Sealing issues

  14. Electrolysis http://www.fuelcells.org/ced/career/scienceproject.pdf

  15. Thank you • Questions • Suggestions • Recommendations
