Wireless Energy Transfer
Here's an innovation that will blow you away if you've not heard about it. It's called Wireless Energy Transfer, and it's going to change the way all electronic devices work, especially TVs.
Look down the back of any TV stand and you're likely to be confronted by a monster of un-sightly cables. And anyone who has tried to wall mount their new TV will tell you what a pain working with the cables can be. Wireless Energy Transfer does away with all cables and transfers electricity to your TV using a transmitter and reciever.
It's not unlike Wifi in that before everyone had wireless routers, hooking a computer up to the web used to involve running some pretty thick networking cables around the home. Today wireless networking is common place and you can work on your laptop from any room you want. Wireless Energy Transfer will do the same thing for our home entertainment products.
So how far have Sony got? At the moment energy transfer is still in an experimental, prototype phase. Sony have managed to create a system whereby they can transfer 602 of electricity over a distance of over 50cm. That's enough to have the TV set on a stand, without the need for a power cable.
Energy transfer might sound dangerous, but it's actually safe. If you were to place a piece of metal between the transmitter and reciever, it wouldn't get hot. There's no heat induction whatsoever. There are however a number of problems that do need ironing out.
Transferring energy over a distance isn't the most efficient of processes. At the moment, over a distance of 50cm, around 20% of the power is lost. And distance is another problem. The more distance you want to transfer power over, the larger transmitter and receiver you need. One answer to this is to use what are called passive extender units, which sit between the receiver and transmitter and relay the energy. Using these, Sony can boost the distance up to 80cm, without losing energy efficiency.
It's not hard to see the lure of energy transfer systems for uses in the home such as home entertainment systems and mobile computing. Who wouldn't want to get rid of that mess of wires, or be able to lose the weight from a laptop, and not have to worry about battery life. It's something that Sony are sinking a lot more time and money into, and it's no doubt going to be a spec we'll be taking into consideration when buying TVs in the future.
