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.
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.

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.

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