Nerd alert! - Magnetic Shells -

As indicated in earlier studies and as observed in Nature, it is indeed possible to transfer magnetic energy from one point to another through a non-magnetic medium or empty space.

A general property of magnetic fields is that they decay with the distance from their magnetic source. But in a new study, physicists have shown that surrounding a magnetic source with a magnetic shell can enhance the magnetic field as it moves away from the source, allowing magnetic energy to be transferred to a distant location through empty space.

By reversing this technique, the scientists showed that the transferred magnetic energy can be captured by a second magnetic shell located some distance away from the first shell. The second shell can then concentrate the captured magnetic energy into a small interior region. The achievement represents an unprecedented ability to transport and concentrate magnetic energy, and could have applications in the wireless transmission of energy, medical techniques, and other areas.

The way how scientists from the Autonomous University of Barcelona were able to manipulate magnetic fields is remarkable. Enhancement, transfer, concentration and capture, all with an experimental set up that is rather simple.


[The newly designed magnetic shell can either expel or concentrate magnetic energy. In the left panels, a small dipole magnet in (a) is surrounded by a magnetic shell in (b), which expels its magnetic energy further outward. In (c), a second shell harvests the energy and concentrates it into its center hole; in this way, magnetic energy is transferred through empty space. In the right panels, two dipole magnets in (d) are surrounded by shells in (e) that expel their magnetic energy. As shown in (f), the result is magnetic coupling between the two dipoles.]




[Magnetic shells can be used to increase the magnetic energy of multiple magnets: The four magnetic dipoles in (a) interact very weakly, even when they are moved closer together in (b). However, when all four dipoles are surrounded by a shell as in (c), their exterior fields become enhanced, yielding a stronger magnetic field in the center region.]

Magnetic energy is one the main agents powering our society: generating energy in power plants, keeping information in magnetic memories, moving our devices with motors. All of these applications require a certain spatial distribution of magnetic energy, for example concentrating it in a transformer core or in a magnetic sensor.

We introduce in this work a way to collect magnetic energy and distribute it in space with unprecedented efficiency and flexibility, allowing very large concentration of magnetic energy in a free space region, an enhanced magnetic coupling between two magnetic sources, and the transfer of magnetic energy from a source to a given distant point separated by empty space.
All these features are achieved with a single device, a magnetic shell designed by transformation optics.

Magnetic energy harvesting

Quite awesome.

I wonder how this correlates with the work of Tesla. I do believe his last task, which was stopped by the government, Edison and friends, was to set up his coils and transfer electricity over long distances. Sounds similar to the methods described in these magnetic experiments.

Interesting.so, the Star Trek transporter thingy might actually be possible.

This is really interesting. Thanks.
What are these shells made out of?

Nevermind.
"Although no material exists that can perfectly meet the requirements for the magnetic shell's properties,"

There might be a correlation, the difference is, to explain Tesla's electrical energy transfer would require to extend Maxwell’s (simplified) equations to longitudinal dielectric waves.

Tesla Waves


Probably totally unrelated effect, but i'll put it here for the Nerd Factor.

How well can the direction towards the destination be controlled?

We could harvest the magnetic energy from the sun and focus it to the earth to harness an unprecedented amount of free energy .

Can it be done efficiently?

Magnetism relies on moving charges.
Thus an oscillating field is a source for the moving charge and mag field.
I don't think this is a large scale operation being a.u. measurements.
Thus Tesla did the most with breaking air or dark matter resistance to
energy transfer in feet and miles while this must be a electron microscope
scale operation.

edit on 8-1-2013 by smithjustinb because: (no reason given)

I think Tesla considered the Suns in the universe to be sending out shock waves in the
ether and particles which could be captured in tubes for electrical charging of batteries
that he showed in the so called radiant energy patent.
