Lucas123 writes "At Disrupt this week, Ossia Inc. demonstrated for the first time its wireless charging technology that founder Hatem Zeine said has a 30-foot radius and, like WiFi, can charge through walls and 'around corners.' The technology, still in prototype phase, uses the same spectrum as other wireless standards, such as WiFi and Bluetooth. The Cota wireless charging system includes a charger and a receiver — either a dongle device or chip-tech integrated into a product, such as a smartphone or battery. While it has yet to be miniaturized, Zeine said the wireless technology will eventually be small enough to fit into a AAA battery or any portable electronic device. While the technology has wider industrial implications, as a consumer product, a charging unit will likely sell for around $100, he said."
