  1. Wireless Electricity The End Of The Plug?

  2. What is it? • Based on electromagnetic induction (using conductive materials in coils to create a magnetic field) • Resonant Magnetic Coupling: when two objects exchange energy through their varying or oscillating magnetic fields. -Natural frequencies of the two objects are approximately the same. —Source: http://en.wikipedia.org/wiki/Wireless_electricity

  3. HOW WIRELESS POWER WORKS • 1. Magnetic coil (Antenna A) is housed in a box and can be set in wall or ceiling. • 2. Antenna A, powered by mains, resonates at a specific frequency. • 3. Electromagnetic waves transmitted through the air. • 4. Second magnetic coil (Antenna B) fitted in laptop/TV etc resonates at same frequency as first coil and absorbs energy. • 5. Energy charges the device. Source: www.bbc.co.uk/2/hi/8165928.stm

  4. In Layperson’s Terms • Wireless electricity is the transfer of power to a device over the air. • — It will allow devices to be powered or charged (with the proper wireless attachments) without being plugged into a wall outlet or docked in a charging station. Source: http://www.witricity.com/

  5. How It Will Be Used • Wireless electricity can be used to power or recharge: • Cell Phones • TVs • Computers • Electric Cars • Cordless Tools • Industrial Machinery • Medical Devices (pacemakers, etc.) • Military Devices (unmanned robots, planes) • Consumer Appliances • ANYTHING ELECTRIC!

  6. Future Uses In Business • More Efficient Office Buildings/Factories • Entire office buildings will run on wireless electricity • Employees computers, cell phones, printers will all stay charged throughout the business day • Electric appliances will not have to be placed around power outlets; running cords is no longer a hassle Source: http://www.witricity.com/pages/application.html

  7. Current Uses • Wireless charging pads • Electric Toothbrushes: • Both of these techniques use small electric fields to charge the devices. • Haier America Digital Products group has already developed a HDTV that transmits electricity and the HD signal, making the TV completely wireless Source: http://electronics.howstuffworks.com/wireless-power1.htm http://www.physorg.com/news182608923.html

  8. Benefits • More Reliable/Less Costly - Never run out of battery power in wireless zones - Power transfers more efficiently than through wires • More Convenient - No more changing batteries - No messy cords • Environmentally Friendly - Reduces the use of disposable batteries - Reduces energy loss Source: http://www.witricity.com/pages/application.html

  9. Cost? • Cost is still undetermined • What they say is there are no exotic materials being used that would make it overly expensive • Prices should be comparable to products already out Source: http://www.witricity.com/pages/application.html

  10. Wireless Electricity Here is an example of how this technology works: http://www.ted.com/talks/eric_giler_demos_wireless_electricity.html
