Scientists have sounded the death knell for the plug and power lead.
In a breakthrough that sounds like something out of Star Trek, they have discovered a way of 'beaming' power across a room into a light bulb, mobile phone or laptop computer without wires or cables.
In the first successful trial of its kind, the team was able to illuminate a 60-watt light bulb 7ft away.
It works on the well known concept of electromagnetic induction:
Rather than sending power from a transmitter to a receiver as a conventional electromagnetic wave - the same form of radiation as light, radio waves and microwaves - he could use the transmitter to fill a room with a 'non-radiative' electromagnetic field.
Most objects in the room - such as people, desks and carpets - would be unaffected by the electromagnetic field. But any objects designed to resonate with the electromagnetic field would absorb the energy.
I love it when we find new ways to apply old concepts. Human ingenuity is limitless.
