Wireless Energy Transfer?
Ipod down to its last few minutes of power? Laptop die during your latest Battlefield 2142 clan match? These things will soon be a thing of the past, claims Marin Soljacic of the Massachusetts Institute of Technology. Soljacic and his colleagues propose introducing a short gap in a metal loop and attaching two small disks at each end. When electrified, such an object has a natural, or resonant, frequency that results from current flowing back and forth along the loop from one disk to the other. More here.
“The results are strongly encouraging but the real test of the thing will be experiments, which we are working on now.”
I know I could find a handful of uses for this technology right now. If it does come to light, it will certainly revolutionize portable device usage. Time will tell!
