A team from the Korea Advanced Institute of Science and Technology (KAIST) demonstrated a system that consists of a two 10 foot long boxes backed with magnetic coils and ferrite rods. It has enough power to juice up 40 phones simultaneously. It can also charge larger devices like portable TVs and laptops.

Professor Chun T. Rim from KAIST says that his hope is that wireless charging will soon be as common as Wi-Fi hotspots. Which is great, and that means no more looking for a power point to plug in when you're low on power during the day.
