The majority of Wireless devices will never be truly wireless until the people in white coats crack wireless electricity or WiTricity as it’s been dubbed.
Your mobile, iPod and laptop all need to connected to the mains at some point, which is a real pain if you’ve left it at home.
Apparently a team from the Massachusetts Institute of Technology have made a 60-watt light bulb glow using electricity sent wirelessly between copper coils set seven feet apart. They believe they are between three and five years away from developing a system which could recharge laptops, mobile phones and other devices wirelessly.
Only drawback at the moment is that it only works over a distance of 2 metres and is about 40% efficient. Oh and the magnetic coils used to transmit the electricity are about 2 foot tall.
Still it’s a pretty cool development.
