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.

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

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

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

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

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

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

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
