Unscramble the Blue Letters


What Dr. Soljacic figured out how to do was separate the coils in a troraesnfmr to a greater distance than the size of those transformers using this technology, which is not dissimilar from the way an opera singer shatters a glsas on the other side of the room. It's a resonant phenomenon for which he actually received a MacArthur fwihlolsep Award, which is nicknamed the guiens arawd, last seemebtpr, for his discovery.

So how does it work? Imagine a coil. For those of you that are ereengins, there's a capacitor attached to it too. And if you can cause that coil to resonate, what will haeppn is it will pulse at alternating current frequencies — at a fairly high frequency, by the way. And if you can binrg another dievce close enough to the source, that will only work at exactly that frequency, you can actually get them to do what's called strongly couple, and transfer magnetic energy between them. And then what you do is, you start out with electricity, turn it into magnetic field, take that magnetic field, turn it back into electricity, and then you can use it.

Original Text


What Dr. Soljacic figured out how to do was separate the coils in a transformer to a greater distance than the size of those transformers using this technology, which is not dissimilar from the way an opera singer shatters a glass on the other side of the room. It's a resonant phenomenon for which he actually received a MacArthur Fellowship Award, which is nicknamed the Genius Award, last September, for his discovery.

So how does it work? Imagine a coil. For those of you that are engineers, there's a capacitor attached to it too. And if you can cause that coil to resonate, what will happen is it will pulse at alternating current frequencies — at a fairly high frequency, by the way. And if you can bring another device close enough to the source, that will only work at exactly that frequency, you can actually get them to do what's called strongly couple, and transfer magnetic energy between them. And then what you do is, you start out with electricity, turn it into magnetic field, take that magnetic field, turn it back into electricity, and then you can use it.
