3. 1.Research Purpose
The purpose of this project is to know the new technologies in adapting the wireless energy power transfer and its advantages and disadvantages .
There are three main topics were covered in this project
Types of Technologies that used to transfer the power wireless.
The recent scientific experiments to transfer power.
The third topic is about the advantages and disadvantage of having wireless power energy .

4. 2. Rationale
I become interested in this subject since 2007 when ,I saw a report on the BBC channel about the transfer power without wires.
I started to read about the subject and I decide to chare what I learn about the subject with you .

5. 3. Methodology of the research
In this project , I used many sources as I could to make a good research.
Handbook about the subject.
Download technical papers about the transfer power without wires.
Using internet sites.
Gathering data through survey (survymonke).
Interview with Electric Engineers to clarify some points.

6. 4.Wireless Technologies
The idea of wireless is that we can use any technology without needing for wires
56% of people like the idea of having the power wireless at home .
60% they believe we will have the wireless technologies at our homes in the near future.

7. 5. Recent Experiment Using The Coupling Magnetic Resonance
Magnetic coupling is a technique that has recently been investigated by researchers at MIT .
the electric and magnetic fields produced by antennas can generally be divided into the near field, which is dominant at close ranges, and the far fields .

8. 6.Wireless Power Advantages and disadvantages
The wireless power will make our life easier in terms of eliminating the use of wires in our home and offices.
Items of efficiency which will effects the cost of transfer power the wireless, the existing efficiency is only 40% which means we will pay more of 60% of power we loosed and we did not used

9. 7. Literature Review
Wireless power transfer has been tried many times since the beginning of electricity.
The concept began with the experiments of Tesla around the 1890s and has continued until this day. (Vuckovic, 1990).
Hertz tried to transfer the electric power through radio waves while Tesla’s work was based on much longer wavelengths (Brown, 1984)
By 1980, The main wireless power transfer research was limited to NASA (McSpadden, 2002).
In 2007, New Theory based on the what is called strong magnetic coupling
was invented (Marin,2007) .
In 2009 , New devices are appeared in market .

10. 8. Findings
The following are my findings that could be summarized in the following points :
Transfer power wireless could be dangerous where have been found that 30% of all childhood cancers come from exposure to electromagnetic fields.
The cost of electrical bills will be more due to low efficiency of transfer power (40-50%).
The overall analysis what we can come off, from the survey is that people like to have wireless power but not jeopardize their safety and health.

11. 9. Implications
Some people will not buy this technology because it is not healthy
Users will not pay bills for something they didn’t use

12. 10.Conclusion
In this project , new technologies in adapting the wireless energy power transfer and its advantages and disadvantages were discussed.
The most recent method of transfer power wireless which depend on magnetically coupled resonance technology was covered in detail in this project.
Everybody are supporting to have the latest technology .However , this technology has to a proven to be safe and not creating any risk of their users.
Also, important factor need to be improved in these technologies are the efficiency which has direct impact of the cost.

13. THANK YOU FOR LISTENING

14. Recent experiment using the coupling magnetic Resonance
Magnetic coil (Antenna A) is housed in a box and can be set in wall or ceiling.
Antenna A, powered by mains, resonates at a specific frequency.
Electromagnetic waves transmitted through the air .
Second magnetic coil (Antenna B) fitted in laptop/TV etc resonates at same frequency as first coil and absorbs energy
Energy charges the device

15. Some Applications of Magnetically coupled resonance technology have appeared in the market
