How Metamaterials Will Boost Wireless Power Transmission

Wed, 02/16/2011 - 6:17am
A thin slab of metamaterial increases the efficiency of wireless power transmission by an order of magnitude, say researchers.

Power cables are the bane of modern existence. If you own a desktop PC, a phone and perhaps a media player, you're likely to have at least one power socket that looks like spaghetti junction, which is why there is a growing interest in wireless power transmission. RFID chips have become ubiquitous in the western world thanks to the ability to provide them with small amounts of power wirelessly. But there have been many much more ambitious attempts to devise more powerful ways to transmit power.

The Japanese have a long-standing interest in beaming power to the ground from solar panels in space. With limited natural resources of their own, they see this as one way to secure their energy supply. Read the complete article at: http://www.technologyreview.com/blog/arxiv/26392/?ref=rss
