Unplug to Charge

Above:  Duke's electrical engineering department may have designed a material that can create electricity from WiFi signals around you.

Metamaterials are a group of substances that have unique properties en masse.  They are not found in nature. Rather, they are fabricated in labs and often look like honeycombs. A team of Duke scientists has created a metamaterial that may be able to make energy from ambient radio, microwave, and WiFi signals.  Imagine being able to charge your phone simply by being near a WiFi signal. You would be able to stop in at a coffee shop, check an email, and charge your phone without the need for a plug-in.   It may seem like novel technology, but it’s actual based on the same science used in power mats.
