Wireless Resonant Energy Link

In the experiments have been done by Intel, efficiency has already reached 75 percent. This figure is already very large. However, from the side of the world's energy crisis, the figures were still too small. Intel's research head, Rattner, explaining that the energy wasted is still a big if not done charging. "The level of high efficiency becomes a problem on WREL ( Wireless Resonant Energy Link ), it is almost impossible to be realized."

Levels of efficiency also depends on the alignment of coil and coil wire. When the receiver is rotated slightly, the efficiency decreased dramatically. This is to be avoided by researchers. They replace the coil wires with sensors and microchips that can adjust the resonance in a magnetic field is better


"Electricity could come from the kitchen cupboard," said Justin Rattner. "So, you no longer need to plug the Espresso machine." WREL The transmitter can also be mounted in the wall to supply power to all electronic devices that are in a magical zone. The desk can also be useful to supply and charge the battery all the devices in the vicinity

Bicycle dynamo powered mobile phone charger

Cheap mobile phones Nokia launched four new models, and a dynamo powered mobile phone charger homemade bike first, to help protect its dominant market share in emerging markets.

Nokia controls over 50 percent of sales of mobile phones in India and Africa and has strong positions in new markets.

"Tens of millions of these products will be sold, but the competition becomes more intense because the

Electrical Engineering

Electrical Engineering is the science or engineering techniques to study the properties of electrons or electrical properties are then applied to everyday life.

Electrical engineering was once divided into 2:

* Strong currents, which studied high-voltage electricity, as well as
* The current weak, studying the low voltage.

In addition, electrical engineering can be divided into:

* Electrical Engineering, especially on the electrical properties and utilization of electricity in various fields.
* Technique electronics, especially concerning the properties of electrons and their utilization in various fields.

In line with technological developments, especially in the weak current, the current concentration is divided into six, namely:

* Electric power engineering, which was once a strong current concentration
* Electronics engineering
* Telecommunication engineering
* Control engineering
* Computer engineering
* Biomedics engineering is a multidisciplinary field involving engineering, science and technological methods to solve problems in biology and medicine, to improve the quality of public health.
