  2. Use Case • A soldier in the middle of the desert who needs to completely operate a communication device (radio) by generating all of the energy needed.

  3. Customer Needs Analysis The system generating the energy should- • Produce enough electricity to run radio constantly. • Be easy to operate. • Not affect the soldiers performance ( light weight, camoflauge). • Be environmentally friendly

  4. Target Specifications • Keep a radio continuously running -radio uses about 400 watts/day- so we must produce at least this • Produce this 400 watts/day only using renewable energy

  5. Concept Generation/Benchmarking • Solar panels which uses the sun to generate energy • Body back which uses body heat to generate energy • Friction panels which can be either manually slid or slid as a result of walking, this will generate energy • Clothes out of nanofibers that create electricity when you move around • Hand Crank

  6. Concept Selection • We chose kinetic and solar energy as our most viable options for renewable energy

  7. Costs • Radio-100$ • Suspended load system –300$ • Solar panels-65$ • Charger system(solar panel+ load system)-365$ • The costs are not an issue with a military budget

  8. Block Diagram

  9. Suspended Load System • 1-2 vertical inch hip movement • Frame of backpack separate from the load; this allows the capture of kinetic energy • Load suspended from frame by vertical springs • Gear turns a generator creating electricity

  10. Conclusion - Charging system consists of solar panels and suspended load system combined by a diode; the device then plugs into the charger - The combination of two renewable energy sources- solar and kinetic – meets our target specifications by producing more energy than is consumed -Suspended load system - 7.5 watts after an hour of walking -Solar panels – 80 watts/hour – 400 watts/day -Radio uses – 300 watts/day
