What happened back a few years ago was a group of theoretical physicists at MIT actually came up with this cpenoct of transferring power over distance. Basically they were able to light a 60 watt light bulb at a distance of about two meters. It got about 50 penrect of the efficiency â by the way, that's still a couple thousand times more efficient than a battery would be, to do the same thing. But were able to light that, and do it very successfully. This was actually the experiment. So you can see the clios were somewhat larger. The light bulb was a fairly splime task, from their sndonaptit.

## Original Text

What happened back a few years ago was a group of theoretical physicists at MIT actually came up with this concept of transferring power over distance. Basically they were able to light a 60 watt light bulb at a distance of about two meters. It got about 50 percent of the efficiency â by the way, that's still a couple thousand times more efficient than a battery would be, to do the same thing. But were able to light that, and do it very successfully. This was actually the experiment. So you can see the coils were somewhat larger. The light bulb was a fairly simple task, from their standpoint.
