In the smart home of the future, the wireless energy transfer can be done easily as wireless internet.Katie Hall was surprised to see a light bulb shines in the middle of the room without a rope tied at all. Looking back, she discovered it was an experiment. She remembered the picture of the power lines behind ngoang diluted a refrigerator.She walked through the steps between the coils and light bulbs - light bulbs still on. She said: "It is necessary to learn this. This is the future.

"Electricity will be transmitted as wireless internetDr. Katie Hall (left in red) is playing laptop charging without plugging into an electrical outlet'

Katie Hall is a PhD and now she is the Chief Technology Officer at WiTricity - a newly established company which specializes in developing technology for wireless resonant."But we really do not put power into the air. What we are doing is putting on the air field, "she said. Can be explained like this, WiTricity build a "resonator source" - an electromagnetic coil generating a magnetic field when power. If there is one other coil is brought closer, there will be a charge is created, without any string section."When you bring a device into a magnetic field, it creates an electric current in the device, and in this way you can conduct electricity," said Dr. Hall explained. Thus, in the experiment bulbs were illuminated.You do not have to worry about the risk of electric shock. Hall ensures that the magnetic field is used to transfer energy "absolutely safe" - in fact, we are like a magnetic field is used in the form of Wi-Fi router.

And in the house of the future, the wireless energy transmission can be done easily as wireless internet.

If everything goes according to plan of WiTricity, a smartphone in your pocket will charge the users when they are traveling and not having to plug into a power outlet, the TV will play without any piece of wire, and electric cars will refuel while running in the streets.WiTricity demonstrated the ability to recharge the laptop, cellphone and TV by attaching the coils resonate in battery. Hall has a bright future to look out for the family when not entangled in power lines. "We will not think about it anymore: I would drive home and I never have to enter the gas station, never have to plug the car charger. I can not even imagine things will change how they live in wireless computing environment. "Electricity will be transmitted as wireless internetThe house of the future will entirely be freed from the power cord ngoang dilutedBehind the application saves this effort, Hall also overlooks the revolution. When Hall first saw wireless power ball, she immediately thought about medical technology - the implantable device can be charged without the touch. Currently, WiTricity is working with a medical company to charge cardio equipment. Technology has opened the door for any portable electronic device does being "tied up" the battery."The idea of ​​getting rid of wires would allow us to redesign everything in ways that we never thought of, that will help the equipment and everything that we use becomes effective better, more practical and can even bring more functionality, "Hall said.The challenge now is to increase the distance that power can be transmitted efficiently. According to Hall explained, this gap related to the size of the coil, and WiTricity wants to complete the distance electricity transmission. So, WiTricity is hope for a new creation: the wireless rechargeable battery AA size.As for Hall, the application is extremely. That's when people will not have to plug anything to recharge.
