Last year, we’d learned that some researchers in the US were working hard to establish a way to transmit electricity wirelessly. And it seems like they have little solid achievement here.

Intel has demonstrated their new wireless power technology at this years IDF, which sounds pretty promising that electricity will soon be able to be transmitted in the air to your gadgets. The demo consists of two metal arrays that connect to a power amplifier. These arrays resonate to establish a link of energy between them.

The wireless electricity transmission isn’t new here, but Intel is the one, who can achieve the best efficiency, which they’re now able to deliver a 75% of efficiency while transferring 60 watts of power over a distance of two feet.

The wireless electricity is still not ready yet to be used to charge your gadgets. But it shouldn’t be too far from reality as Intel’s been pretty aggressive into making it to work. It could be not far in the future, wireless power transmission to your gadgets to juice them up is all made possible.
