I ran across this article and found it to be quite interesting. I am not academically versed to understand the physics of this application, but it seems that it could have huge impact within the electrical and electronic engineering fields.
How does this efficiency compare with current methods of transmitting via a wire? Would it be possible to transmit power over extremely long distances with this, or will the inverse-square law play a role?
Like I said, I don't know any physics as of yet, but I found this story to be interesting and it perked my imagination.*EDIT* If I'm not mistaken, a laser is simply highly concentrated light radiation; so would that make this "Anti-Laser" a super-photovoltaic? That's probably a stretch.

In a paper published in the journal Science they demonstrated that the anti-laser could adsorb 99.4 per cent of incoming light, for a specific wavelength.
