1. WIRELESS POWER

2. 0 All of the devices we use in our every day life need battery in order to work. 0 Most of the people do not have any battery left on their devices by lunch time. 0 Scientists are trying to develop a new technology which is called Wireless Power.

3. History 0 First researcher of Wireless Power is Nikola Telsa in 1891. He wanted to give Wireless Power to the world. 0 In 2009, HP created the smartphone called Palm Pre with Palm touchstone wireless charger. 0 In 2012, a group from the University of Utah developed an efficient wireless power system for biomedical implants. 0 Recently, in 2013, a concept of a virtual waveguide controlled by magnetic fields for wireless power transmission was proposed.

4. Technology 0 This technology requires two coils the transmitter and the receiver. 0 A current travels in the transmitter coil generating a magnetic field. 0 This generates voltage in the receiver coil therefore generating energy.

5. Advantages 0 Always have our devices charged 0 Cleaner Earth 0 Significant reduction of carbon emissions

6. Disadvantages 0 Exposure to magnetic radiation 0 Who is going to pay for it?? 0 Government regulations on where each product can be sold 0 The Idependent Scientific committee has published guidelines for a maximum exposure

7. Conclusion 0 Always need battery in order for our devices to work 0 With Wireless Power Technology devices will be fully charged all the time 0 Wireless Power will free us from having to carry chords and cables around and finding plugs to connect our devices. 0 Wireless Power will be everywhere in a few years, from cellphones to automobiles
