Wireless Charge Transfer

Imagine a future, where charge is transferred through towers, recharging your mobile while, even, walking in the streets, without any physical connections, the charge being shared like Bluetooth, Internet. Charging your electronic devices without plugging in, can certainly, give you relief from those ubiquitous power wires, furthermore, some device might not need their bulky batteries to operate. With no doubts, this innovative idea can be the cornerstone in developing human civilization and can provide new scope in technological field. Since, this technology can play vital role in our daily life, many scientists and engineers are giving their effort towards this wonderful concept.

Different methods of transmitting power wirelessly have been known for centuries. Perhaps the best known example is electromagnetic radiation, such as radio waves. While such radiation is excellent for wireless transmission of information, it is not feasible to use it for power transmission. Since radiation spreads in all directions, a vast majority of power would end up being wasted into free space.

But, Team from MIT, in 2006, showed this idea can be true and applicable. They proved it by lightning the 60 Watt light bulb from the power source seven feet away without any physical connections and named it as WiTricity. This was all based upon The Magnetically coupled resistor. It has got simple logic. For instance, if we take 10 wine glasses and pour water with different level so that all have their own unique resonant frequencies. A high pitch singer is allowed to make a high pitch note, and the glass of corresponding frequency might accumulate sufficient energy to explode the glass. Likewise, WiTricity is also based on using coupled resonant objects. Two resonant objects of the same resonant frequency tend to exchange energy efficiently, while interacting weakly with extraneous off-resonant objects.

This idea is being investigated to uncover more and more informations behind it. It doesn’t only revolve in the mind of Genius, but also catches concentration of normal people. So let’s hope, application of wireless charge transfer be introduced in front of the mass in near future and even, let’s hope the technological field gets more advanced and digital.
