Fujitsu unveiled their new technology at an engineering conference in Osaka, Japan. Their wireless charging technology uses magnets to be able to charge more than one gadget at a time wirelessly and could lead to the introduction of public wireless charging 'hotspots' by 2012.

Unlike current wireless charging systems, which use electromagnetic induction between two coils, Fujitsu have used magnetic resonance. Electromagnetic induction, used in things like cordless phones, only works over short distances with the power transmitter and receiver in alignment.

Magnetic resonance sends electricity between two coils that are tuned to the same frequency and can transmit over distances of several metres and could power multiple devices including electric cars.
Fujitsu said: "This technology paves the way to integrating compact wireless charging functions into mobile phones and enabling multiple portable devices to be charged simultaneously without any restrictions on their position with respect to the charger."

Do you think we will soon be using public charging 'hotspots' and charging our electric cars with mobile systems? Leave a comment and share your thoughts.
