An old idea that electricity needs wire to travel. That is going to change in near future. The idea of cordless electricity is not a new concept. It was tried century ago. The researches are going on and few companies claim that we are only 3 to 5 years behind when solution will be commercially available.
You may be surprised that to use your computer or laptop or even kitchen appliances, you may not need wires to connect to electrical outlets. You can power your laptops with magnetic field.
Actually the idea was tested by Pittsburgh based company in 2003 on a LED 1.5 miles away from the electrical outlet. Though there are some unanswered questions are still there like effect of magnetic field on human body exposed for a longer duration of time. But hope with time we will have a solution for this also.
If the solution is successful it will force changes to many businesses including electric cars to look into their products and redesign.
