In the world of tomorrow, charging your cell phone could be a breeze.
A team of researchers at University of Texas developed a prototype of a wind turbine—half the size of a grain of rice—that could be integrated into future electronics. Made from durable metal alloy and connected by tiny wires, it would deliver a tiny burst of energy to compact devices—think smartphones, not refrigerators—that need quick juice.
It’s the latest mobile-technology idea aimed at making power outlets obsolete. Solar backpack that charge handheld devices already exist. Next up? A new generation of wearable energy sources could include solar-powered fabrics and wind-powered hats that restore a phone battery.
