Wireless Electricity.

 A team of US researchers has come up with an electricity system that does not need wires. This is a breakthrough in what will hopefully be a wireless future. The scientists, from the Massachusetts Institute of Technology, lit a 60-watt light bulb using magnetic fields. In the test, the power source was just two metres away from the light, but the team hopes they will soon be able to send electricity longer distances through the air. They have dubbed their new invention “WiTricity”, or wireless electricity. Although wi-fi has been around for some years now, it has been limited to the transmission of information, especially between computers and modems, printers and scanners. This is the first time electrical appliances have been powered wirelessly.


This new development means that our houses may be free from tangled wires. Gone will be the days of having to unplug the vacuum to go from room to room, and of having countless plugs hidden behind the TV and stereo. The new source of delivering power to gadgets remotely may also reduce the number of fires caused by poor wiring and overloaded sockets. It turns out the concept is not so new. A century ago, inventor Nikola Tesla struck upon the idea of building a huge tower in New York that would wirelessly beam power to the city. Unfortunately, his idea never came to fruition, until today, that is. It will still be a while before we have wireless homes and offices. Safety experts will be checking closely to ensure the power source causes us no harm.

  • How would "wirelessness" make our life better?
  • Match underlined words in the text to these meanings:
  - completion: fruition
  - gadgets: appliances
  - spread: transmission
  - jumbled: tangled
  - faulty: poor
  - invented: come up with
  - send out: beam
  - called: dubbed
  - revolution: breakthrough
  - thought of: struck upon
  • You can find out more about WiTricity in their website.

The Future.


These are some predictions for the future. What do you think? How many will come true?
