Nagano Japan shows off yet another contactless charging system

It's been little over a month since Showa Aircraft demonstrated a contactless charging system that boasts 90% efficiency over a distance of 60 centimeters -- and now what is this? Nagano Japan Radio Co Ltd. is touting a similar system that works up to one meter, with a pretty incredible 95% efficiency at a distance of 40 centimeters.

According to Tech-On, the company is currently hard at work trying to ramp the output up from "several tens" of watts to several kilowatts. As opposed to Showa's recent outing (which relies on electromagnetic induction), this system uses magnetic resonance to achieve its effect. However, as this method "drastically lowers" its efficiency when the position of the sending and receiving units are displaced, the team designed a system that automatically detects coil displacement and reorients itself accordingly.

    • I'm actually getting quite excited about the idea of wireless electricity, its the one cable that most gadgets needs and it irritates me.

      Bring on the days of the totally wireless TV's......

      Agreed, I look forward to it as well. The dream of Tesla coming to reality. Absolute genius.

      I think it's a whole bunch of poppycock that these can be harmful
