Intel demonstrated a technology it has been working on for quite some time yesterday at IDF. It's a wireless power technology that could point to such nifty things as wireless battery chargers in the semi-near future.
The demonstration showed a setup of two metal arrays that connect to a power amplifier. These arrays resonate in order to establish a link of energy between them. This allows for the transmission of power from one metal ring to another.
Even though this sort of technology isn't new, Intel has gotten the highest efficiency so far of 75% for transferring 60 watts over two feet. The bad news is this tech isn't suitable for your beloved gadgets just yet. But that's okay. It seems Intel is well on their way to developing this into something usable.
