WOW... Electricity supply without wires!
Finnish scientists have created a sensation by transmitting electricity through the air without wires. Scientists from Helsinki and Oulu Universities successfully transmitted electricity from one place to another using ultrasonic sound waves and laser beams. This 'acoustic wire' technology, which is in the experimental stage, will reduce the need for plugs and wires in the future. Similar to Wi-Fi, power will be supplied to devices through radio waves.
