Device Turns Stray Microwaves into Energy

Scientists have built a device they say can capture stray microwave signals and convert them into electrical power capable of recharging a cell phone or other small electronic device. Researchers at Duke University’s Pratt School of Engineering in North Carolina say the device is similar to a solar panel and has a similar efficiency, and while it harvests microwaves, the researchers think the harvester could be tuned to harvest the signal from other energy sources, including satellite...
