Wireless power has been on my “want” list for a long time. I imagined just being able to put something in a room and it some how gets power. This is now becoming a reality. When you look behind the TV you always see a mass of electrical cables, ariel’s and other cables. Networking is becoming wireless, so these wires have been removed almost. However, there is a mass supply of power leads ranging from yout TV, DVD player, VCR, Cable box, Networking and sometimes others too. Over the last year or so we have seen mobile phone chargers that work by placing the phone on it. This new system takes it a step further by being able to charge devices over a distance away of many metres.
The system is just theory now and has not been built yet. With the help of computing power they believe it will work. It works using resonance which causes an object to vibrate when a certain frequency is applied. What this means is that anything compatible in a room will automatically charge such as a laptop you are working on can be kept powered by this resonance.
It seems like we truly can become wireless eventually.
