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

Block Diagram

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
