The End Of The Plug?

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.

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.

In Layperson’s TermsWireless 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.

How It Will Be UsedWireless 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!

Future Uses In BusinessMore 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 hassleSource: http://www.witricity.com/pages/application.html

Current UsesWireless charging padsElectric 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

BenefitsMore 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

Cost?Cost is still undeterminedWhat they say is there are no exotic materials

being used that would make it overly expensive

Prices should be comparable to products already out
