Get this; you can soon recharge your laptop, cell phone, or other gadgets wirelessly. How fascinating is that?
According to Marin Soljacic from MIT's Department of Physics and Research Laboratory of Electronics, technology may transmit electric charge wirelessly. How will it be possible? According to Marin, through electromagnetic radiation in the form of radio waves. But because of the nature of these waves, the energy is transferred in a burst of directions, not very efficient. The way to go around this problem is to focus the transfer of energy. This can be done through a focusing mechanism, but not by pointing one device to another. Instead it is done by filling the space with a non-radiative electromagnetic field. Only those devices that can resonate with the field can pick up the energy, quite crafty huh?
If you peek into the future of this technology you will it to be tremendous. Charging your laptop wirelessly is something that gives the word wireless-connectivity a whole new meaning. Read more here.
