1. Technical Presentation Rob Haberstroh

2.  Brief History  Types of wireless power transmission  Examples  Future Outlook  Conclude

3.  Heinrich Hertz ◦ Electromagnetic radiation(1888)  Nicola Tesla ◦ Tesla experiment(1894)  William C. Brown ◦ Rectenna(1964)

4.  Current moves through wire  magnetic field  Place another coil into field  Creates power/charges battery

5. CarsCell Phones

6.  Coil of wire with capacitance plate at either end  Alternating electric current causes resonance  A second coil with same resonance frequency picks up the energy

8.  Microwave transmitter sends microwaves  Rectenna converts into DC

9. SHARPPower from the Moon

11.  Hertz, Tesla, Brown  Inductive Coupling  Resonant Inductive Coupling  Microwave Power Transmission  Projected Increase in the Future
