No cords necessary

Chargers and cords can be unplugged and tossed as wireless energy transfer is becoming better able to serve consumers.

Marin Soljačić, a physics professor at the Massachusetts Institute of Technology, began developing wireless energy because he was tired of being awakened by his wife’s cell phone alerting her about a low battery charge. Over the past six years, the work of Soljačić and a team of MIT researchers and engineers has led to their establishing of a wireless electricity company called WiTricity.
