What I’ve Got: Charging Devices over Wi-Fi


New metamaterial applications researched at Duke University, when used in battery-powered electronics, may one day permit them to charge by harvesting energy off wifi networks. In addition to being convenient, research indicates that this will be more energy efficient than charging via USB. This solution’s key observed details are the prevalence of wifi and the inefficiency of USB charging. The solution is completely organic because it can be implemented automatically. Finally, the solution feels very human, as it fits seamlessly into the ordinary person’s lifestyle. This is a very desirable technological advance that I hope to see implemented in future electronic devices.
