Imagine a future in which wireless electricity makes everyday products/gadgets more convenient, reliable, and environmentally friendly.
Cell phones, iPods, laptop computers, capable of recharging themselves without being plugged in. Flat screen TVs, CD players, without requiring a wire and a socket for power. All these are in the not too distant future.
A new company, WiTricity is working on a Technology that wirelessly powers gadgets. The company was founded in 2007 to commercialize the technology which was invented two years earlier in Massachusetts Institute of Technology (MIT).
To simplify, wireless electricity transmission is caused by electric current at a specific frequency running through one coil, which causes a magnetic field oscillating at that same frequency to be emitted from the coil. When that magnetic field comes in contact with an identical coil at another location, the 2nd coil resonates at the same frequency as the magnetic wave and a current is induced in the second coil.
WiTricity technology can be used to provide direct wireless power to a device within the range of its WiTricity power source and automatic wireless charging for devices with rechargeable batteries while still in use or at rest without requiring power cord or change of batteries.
So if anyone is excited about the technology , Eric Giller, CEO of Witricity predicts that:
…electronics such as phones and laptops may start shedding their power cords within a year.
He seems to be right because Computer manufacturer Dell, recently unveiled a new system, Latitude Z which is capable of full recharging of its batteries wirelessly with the aid of a wireless docking device.
It is estimated that companies make about 40 billion disposable batteries each year and wireless electricity when widely adopted will do away with that which makes the technology environmentally friendly. Soon, the days of buying such batteries and tripping over power cords will soon be over. In the meantime, be sure to leave a comment about what you think about wireless electricity especially how you think it will change your life.
