Forget all of those charging devices and cables! Physicist Hatem Zeine, founder of Redmond based Ossia Inc, has invented a device that can transmit wireless power to wireless devices. He says Cota, using the same unlicensed spectrum as WiFi and Bluetooth, can charge an iPhone from 30 feet away through walls and closed doors. He predicts everything from smoke alarms to electric toothbrushes will soon be "Cota enabled" . His start up has already raised $3.2 million from investors. Look for $100 Cota chargers to hit the market sometime in 2015.
