One of the most important things in today’s day to day life is electricity. Almost all of our work is dependent on electricity.
It is one of the solution for underdeveloped, developing country to became developed country.
The uses and values attached to electricity are uncountable. If fact, almost all activities in life are connected to electricity.
The important and values of ICT today cannot be accomplished without electricity.
We have different methods of generating electricity such as hydropower, wind, solar, generator and so on
But WiTricity is another source of electricity which is the transfers of electric energy or power over distance without wires.
WiTricity is nothing but wireless electricity. Transmission of electrical energy from one object to another without the use of wires is called as WiTricity.
WiTricity will ensure that the cell phones, laptops, iPods and other power hungry devices get charged on their own, eliminating the need of plugging them in.
Imagine coming home and dropping your phone, laptop, and Bluetooth headset on your kitchen table so that they all recharge, simultaneously.
Principle of WITRICITY
The basic concept behind this is Magnetic Resonance
Power from mains to antenna, made up of copper.
Antenna resonates at a particular frequency producing electromagnetic waves.
‘Tails’ of energy from antenna ‘tunnel’ up to 2 meters.
Electricity picked up by laptop’s antenna, which must also resonate at the same frequency as source. This energy is used to recharge device.
The residual energy is re-absorbed by source antenna. People/other devices are not affected as frequency is not same as source.
