2. To come up with a device that uses two alternate sources of energy to charge a mobile device O BJECTIVE

3. N EEDS AND REQUIREMENTS To develop a solution that would be useful in many situations where a standard wall charger would not be available. (Ex. desert, out at sea) Combine two different sources of alternative energy Portable (small/light weight) Easy to use and safe Durable in extreme environments

4. IDEA #1 “S HOE C HARGER ” Utilizes Kinetic and Thermal energy Kinetic energy From movement inside sole Thermal Energy change of body temperature via the feet

5. IDEA #1 “S HOE C HARGER ” Estimated Weight: 1 pound Easy to use. “as easy as putting on a shoe.” Affordable save you money in the long run Disadvantages Restricted to using only that shoe Selection may be limited

6. IDEA #2 “W INDMILL SOLAR CHARGER ” Utilizes wind energy and solar energy Wind energy taken from the wind Solar energy taken from sun

7. IDEA #2 “W INDMILL SOLAR CHARGER ” Estimated weight: 2 pounds Easy to set up and safe to use Affordable price Recycled materials Disadvantages May end up not sunny and windy at the same time Can only be used outside Not easily transported

8. FINAL PROPOSAL “S OLAR C RANK CHARGER ” Utilizes Solar energy and Mechanical energy Solar energy taken from sunlight Mechanical energy taken from when user turns the hand of the crank
