Two electrical engineers J-C Chiao and Smith Rao of the University of Texas have developed a wind turbine that is half the size of a grain of rice. It is one of the attempts at making power outlets obsolete. It is made of a durable metal alloy and connected by tiny wires that would be integrated into an item such as a smart phone. This in turn would deliver a tiny burst of energy. Other such items in the development are solar powered fabrics and wind powered hats. The tiny turbines would make the solar backpacks a thing of the past.
