Ahhhhhh.... wat's this... Is it ever possible... will such thing happen... am i a fool to talk about such impossible stuff.... all these things came up to my mind when I first thought if we can have wirless power transmission just like wireless data transmission... this thought came into my mind when i was sitting in one of our office conference rooms with my laptop and my laptop ran out of battery.... that made run to find a power adaptor and then a plug point to connect.... if at all we have wireless power transmission how good it will be... then immediately i did some gooogling and found that people have indeed acheived this long back... i m too late in thinking about this...
