Group of experts from Institute of lasers at university of Osaka and the Japanese space agency (JAXA) have developed the effective converter of light, thus, having made an important step on a way towards creation of space solar power station.
It is necessary to note, that the idea of the light converter is not new, however physicists from University of Osaka have managed to overcome a number of problems which arise in creation of such device. They have created an unusual ceramic material, which contains chromium and neodymium. The plate from this material transforms falling light to a laser beam with surprisingly high efficiency - 42 % that is approximately in 4 times higher, than in the previous similar experiments.
And though the final project of such station is not ready yet, Japanese claim that the satellite with a solar collector in the size, for example, in 100×200 meters could redirect to the Earth powerful enough and beam which would be transformed to electricity. According to their calculations, power output of such station would make 1 Gigawatt.
