Massachusetts Institute of Technology after four years of research, developed, known as laptop battery "wireless power" technology, you can隔空provide electricity for the computer or cell phone, cable and batteries in the future are likely to become history.
According to the research, Massachusetts Institute of Technology researchers used two copper coils 2 m apart, successfully passed through the electromagnetic resonant wireless power transmission principles of wireless transmission, a power light 60-watt light bulb. Massachusetts Institute of Technology professor of physics at Ma Liner Jiaxi Ke said that this has been enough to supply a laptop computer power needed.

Like theater singer can shatter glass, like
The idea of wireless power transmission has long been compaq v2000 battery proposed, but was a lot of scientists think that there can not be achieved. Last fall, has proposed aby "radio can transmit" technology using a new theory of electromagnetic energy. In accordance with's theory, as long as electromagnetic energy transmitter with the receiver equipment at the same resonance frequency, the energy between them can be interchangeable.
"It's like theater singer can shatter like glass,"said, "on condition that both the singers and glass to form a resonant sound." In this theory, based on team led by six people in the experiment. They used two copper coils act as resonators. A coil with the power supply connected to a transmitter; the other with the lamp connected to act as a receiver as a result, they succeeded in pulling a 2.1 3 m away from the transmitter outside the 60-watt lamp lit.
In this experiment, the transmitter does not emit electromagnetic wave to the surrounding environment, but the whole space is filled with "non-radiation," EMF, as long as the receiver specially designed to form resonant with the electromagnetic Presario V2000(compaq v2000 battery) field, it will receive the energy.

On the human body does not produce harmful

Experiment also showed that "radio is able to carry" technology harmless to humans. Because the electromagnetic field only to be able to resonate with the items affected, such as human, tables, blankets and other items to the electromagnetic field almost no response. Next, the research team were to be carried out is to try to increase the transmitter power, as well as the efficiency of the receiver's reception. By that time, mobile phones, laptop computers can be configured with the transmitter inside the house to the automatic charging, do not even need batteries, do not need to connect through the socket and power supply can be used directly.
The researchers believe they have 3 to 5 year period will be able to develop a mature system for portable computers, mobile phones, MP3 players and other electrical devices wirelessly. Once the realization of such a wireless power transmission, it means that some small devices can permanently get rid of the shackles of the battery so as to prevent environmental pollution caused by Presario M2000(compaq m2000 battery) discarded batteries.

Battery resonant principle: What is a resonance it! Our more familiar with the swing, for example. When a child sitting on swing, his body swaying frequency and the frequency of the swing the same, it will resonate, and then children will be able to hold
Continued to provide energy to the swing. Again, the sound resonance. If a room in which there are 100 the same bottle, each bottle of wine poured into different amounts, then all bottles of the resonance frequency is not
With the. However, if there is opera singer, singing loudly in the room, then a note, with the same frequency that the bottle notes may receive and accumulate energy. Or even explode, while other wine
Bottles were not affected. Resonance similar to the above, when the objects between Pavilion ZE2000(hp ze2000 battery) the strings with the same resonance frequency, it is possible the effective realization of wireless power transmission. Research team applied to the resonance of electromagnetic waves to pass
On. They used copper coil as the electromagnetic resonator, a coil attached to the transmission of electric power corporation side, the other group receiving the power side. When the transmission side of a specific frequency of electromagnetic waves sent out, after the electromagnetic
Field of radiation to the receiving party, the power to achieve the wireless transmission.
