  1. DESIGN PROJECT II Section 10, Team 3 James Coyne KaitlynMinyon MaddiePattock Chris Rezpa Donavin Stanley

  2. Use Case • mountain climber climbing Mount Everest • no access to AC or vehicle power • needs to be lightweight

  3. Our Solution • Alternative Energy Backpack • Solar Powered Panels • Wind Turbine • Kinetic Energy • Thermoelectricity Energy • Not only a source of energy, but its practical • Still carry his essentials while charging his battery packs

  4. Wind Energy • Average Wind Speed ~ 175 mph • Pmax= ½ ρ A V3 • 3.81 cm • A= .00456 m2 • Ρ = .36 kg/m3 • V = 30 m/s • Pmax = .049 W • May not seem like much, but after a full day, it adds up • On our backpack: • Sticks up off the back

  5. Solar Power • Photovoltaic cells • Sunlight excites electrons; break free • Flow in a current, creating energy • Silicon is the semiconductor • Max efficiency: 293 W • On our backback: • 6 Solar Panels

  6. Thermoelectricity Energy • Average temperature ~ 10°C • Our thermocouple • Handwarmers for heat • Snow for cold • On our backpack: • Drinkholders on the sides

  7. Kinetic Energy • Energy made from crank ~ 5 volts • Energy from magnetic shake weight ~ .2 volts • On our backpack: • Magnets: on the base • Crank: on the side
