Chinese scientists to build "artificial black hole" use of solar energy absorbed


According to the British "New Scientist" reported that, at present, scientists have constructed the first time, can absorb light around the artificial magnetic "black hole." The device can absorb solar energy, can be transformed into the use of heat or electricity.


This man-made black hole in the microwave frequencies, the near future will be able to absorb visible light, is harvesting solar energy generated electricity as a new way. Earlier this year, India's Urdu University, Ivica root - Narayan Manuo Wei (Evgenii Narimanov) and Alexander - Kilday Xie (Alexander Kildishev) in the media magazine published a study on how the construction can absorb light desktop black hole theory. Universe, black holes can simulate the artificial black hole, its strong gravity can bend space-time around, resulting in any material or radiation followed around the twisted space-time, and spiral inward and be absorbed.
Narayan Ma Nuowei and Kilday Xie believes that this man-made black hole can bend light absorption to the Device Center. They have designed artificial black hole is a coaxial ring contains the center of the shell cylindrical structure composed of columns. Make a key factor in inward bending of light is the dielectric constant of the coaxial ring shells, which can affect the electrical component of electromagnetic waves, increasing from the outside to the inside surface smoothness, which is similar to near the black hole space-time curvature. When the coaxial ring shells in contact with the center column, coaxial dielectric ring must match the center column, so the light can be absorbed, rather than being reflected.

Currently, China's Southeast University, Nanjing, scientists will Narayan Manuo Wei Tiejun Cui and Qiang Xie, and Kilday the theory applied for the practice, the construction of a microwave frequency of the "artificial black hole." The device uses a "super material" structure into a 60 coaxial rings, it is learned, super-material was used to make invisible cloak.

Each coaxial ring structure of circuit board in a different form of the formation of coaxial rings connected to each other, so the dielectric constant is very smooth. The external shell 40 coaxial rings, the internal 20 coaxial rings absorber. Tie-Jun Cui said: "When the incident electromagnetic wave hits the device, the electromagnetic waves will be induced into the coax inside the ring, and then be absorbed. In the coaxial ring will absorb the light into heat."

Narayan great praise China Ma Nuowei two scientists constructed an artificial black hole, he said: "I am very surprised that they can escape so quickly to complete the construction of artificial black hole!"

This man-made black hole in the same way is not easy to catch waves, visible light wavelengths than the microwave radiation, many orders of magnitude smaller. This requires a corresponding need for the construction of coaxial ring more smaller. Tie-Jun Cui for their construction of artificial black hole full of confidence, he said: "I hope that this optical black hole can be widely used at the end of 2009."

Like this man-made black hole can be used to collect solar energy, especially for solar reflectors are too diffuse, difficult to gather the sun on the solar cell light. Optical Artificial black holes are able to completely absorb the light and absorbed directly into the coaxial ring of the solar cells. Narayan Manuo Wei said: "If this device can work effectively, then the future will no longer need to adopt the parabolic mirror to collect the sun's rays."
