There is no longer need for any wires anymore. First, the remote control lost its wire when it was figured out that electromagnetic waves could send information through the air. Then the telephone cord was launched into the stone age with the advent of the wireless telephone, using the very same principals. Soon the mouse followed, than speakers, than the keyboard then the internet all togeter became free of the ever constricting cord. Today the last remaining cord, the power cord, has been enlisted on the endangered technology list.
Powercast, an east coast technology company that started in 2003, has invented a way to transfer power wirelessly. The company is able to achieve this with almost antiquated technology, radio waves. These wasves are actually hold a significant amount of energy in them, it was just a matter of figuring out a way of efficiently converting these waves into energy on the recieving end. Powercast has been able to successfully convert upwards of 70 percent of the initial energy back into energy at the other end. Previous attempts have really only been able to achieve around 10 percent.
Though the product is limited at the moment. Currently the device is only able to transmit a few milliwatts of energy within a meter of the source. This is not very far of a range and not that much power at all. This power would only charger your cell phone half way if left to charge the whole night.
So hold on to those wires for now but soon, maybe sooner than you think, set them on fire because they will be an ancient relic of early 21 century technology.
