The ever increasing amounts of technology in our homes have brought with it endless chargers cables cradles and cords. Now companies around the world are starting to use a technology invented by Nikola tesla over 100 years ago when he managed to transmit 1 million volts wirelessly over a distance of 26 miles. From Tesla’s initial breakthrough in 1899 research has progressed in the area of RF charging, without knowing to much about the underlying technology, what is clear is that over the next couple of years more and more of our everyday devices will be chargeable without having to connect anything to the mains, just having it in the vicinity of a charger will prove sufficient. The hope is that it will do the same as what wireless has done for the internet.
RF or radio frequency waves have been bouncing around our homes for a while now, but it is only in recent times that the boffins have figured how to tune the frequency of different items to different radio waves.
The most common wireless chargers currently available are the charge pads. Designed for charging small consumer goods, like cell phones, mp3 players, remotes and console controllers. Once the pad has been tuned to the same frequency as the device all the user is required to do is place the device on the pad to charge it. Collectively these charges use a method called inductive charging.
The more impressive forms of wireless charging are the areas where some of the world’s largest manufactures are spending vast amounts on research and development. Radio and Resonance charging.
Radio Charging is an ideal solution for charging a larger volume of lower power usage devices from a wider distance, unlike the charge pads the devices don’t need to be place on or near the pad to charge, once each unit is assigned to a different frequency there will be no issues charging multiple devices from one base unit.
Resonance is most suited for high usage consumer goods, especially many of the white goods found in our kitchens; as this type of charging proves inconsistent over longer distances it is ideally suited for use in the kitchen, where many energy hunger devices are stored in a relatively small space.
Though not quite main stream yet over the next couple of years it will be, with companies like Nokia ploughing vast amounts of money into research and development. It’s most likely that the first real breakthrough will come with cell phones and move on from there. Though there are clear advantages with this new technology there are a number of other advantageous side effects, Cell phones can be fully encased protecting them from dust dirt and in some cases making them waterproof. A single pad will charge multiple item, saving money, no need to replace lost of broken chargers and you won’t have a tangle of wires behind your TV.
