SAN FRANCISCO — Intel has made progress in a technology that could lead to the wireless recharging of gadgets and the end of the power-cord spaghetti behind electronic devices. It says it has increased the efficiency of a technique for wirelessly powering consumer gadgets and computers, a development that could allow a person to simply place a device on a desktop countertop to power it.
