Wireless power transfer over two-meter distance, from the coil on the left to the coil on the right, where it powers a 60W light bulb. Members of the team that performed the experiment are obstructing the direct line of sight between the coils; front row: Peter Fisher (left) and Robert Moffatt; second row: Marin Soljacic; third row: Andre Kurs (left), John Joannopoulos and Aristeidis Karalis.

That’s great so my neighboors can hack in to my “grid” and steal power from me... :)

I don’t suppose the 55% wasted energy would end up heating the air would it?

[Reaganesque]

Anyone here know if this resonance technology could be tuned to use the Earth’s magnetic field as a power source?

How many thousands of homes are burned each year because of electrical short circuits? Elliminating the need for hot wires running to and fro inside your walls would be a great thing.

There is a big problem with the photo of the experimenters. No “diversity”!!.

Why is it that every time a scientific discovery is reported on FR - we have dozens of nay sayers telling us that it is:

a fraud
a stupid idea
A dozen reasons why it won't work
or "this is nothing new."

Is this a forum for Luddites?

I for one, am glad to hear about these stories - technology will continue to make our lives better and better - no matter what these anti-science folks say.

Oh please, give me a break. Wireless power beaming is decades old stuff and has been done on a much larger scale. This is just a slightly different way to do it.

Instead of irradiating the environment with electromagnetic waves, it fills the space around it with a non-radiative magnetic field oscillating at MHz frequencies.

Who ever wrote this seems to have not done a shred of research and does not seem ti know much about physics.

One immediate application would be a wireless sender to charge your car battery before starting your car in the morning. Eureka! No more dead car battery. I've thought of much time and money we waste having to wait for the tow truck to jump start a dead battery when we could take care of the problem at home.

People with pacemakers, ICDs, neurostimulators, and other implanted medical devices would have serious problems if this became widespread.

"Once, when my son was about three years old, we visited his grandparents’ house. They had a 20-year-old phone and my son picked up the handset, asking, 'Dad, why is this phone attached with a cord to the wall?'"

I'm guessing that it's increasingly difficult to find a school-aged kid who has ever seen a television controlled with knobs too.

Beaming power has been around since Tessla.... Which part of INEFFICIENT don't people get? If you think our power grid has issues now, it'll be nothing compaired to the loss of 30% - 60% in these "beamed energy" nightmares...

Too funny, Tesla was doing this 100 years ago...

[SunkenCiv]

alas...

UNPLUGGED. Alternating current fed into a wire loop (blue) generates a field that induces currents in the coil (red, at left), creating a magnetic field that reaches a second coil (red) several meters away (at right), creating a local field that induces a current in the second loop (blue), lighting a bulb. -- Science
