Back Story  Imagine that you are in a meeting on the phone and your phone dies with no way to charge it or continue your meeting.

Initial Problem Statement  3 Words: Scavenging Energy Charge  Problem Statement Today’s batteries die after prolonged use without a way to quickly charge them on the spot.

Revised Problem Statement  Charging personal electronic mobile devices is inefficient and hard to accomplish without direct access to a power outlet.  Design a product that will harness energy in nature and process that power into a charging system

Where We Are Going  A clip system that can be clipped onto almost any material and can harness kinetic motion energy.

Sketches

Power Glove  Takes the movement of fingers to rotate electromagnet creating current.  Current harnessed to charge battery.  Charge pad in the palm to wireless charge mobile device.

Power Suit  The material of the suit is a piezoelectric system designed to harness all movement of the body to a central power location.  Currently not feasible.

Power Clip  Modular design to minimize weight.  Central unit designed to process power to a battery and then to mobile device.  Most feasible.

Decision Matrix

Math and Science Concepts  PE=KE, so KE=mgh for potential vertical motion  Using the walking motion, a magnet can be accelerated up and down changing mechanical to electrical energy (V=I x R (Voltage=Current x Resistance))  The energy can then be stored in a battery for later use.

Summary  Key Requirement: Charge Mobile Device  Where we are going: Power Clip  Any questions?
