Arctic Ozone Hole the Largest Ever RecordedRunning Time : 5minutes Publication Year(JFY) : 2011
Among the many reports of abnormal weather patterns in the Arctic, one piece of news that spread throughout the world in spring 2011 was that the ozone hole above the Arctic Circle had expanded to its largest size ever, with possible consequences on Europe, North America, and Japan. Why did such a significant depletion of the ozone layer occur where it was previously deemed unlikely? What kind of impact did this have on Japan? What is going to happen with the Arctic ozone hole? Dr. Hideaki Nakajima of the National Institute for Environmental Studies has been monitoring ozone over the North and South poles in collaboration with environmental scientists from around the world, answers these questions.
Renewable Energy Wind PowerRunning Time : 5minutes Publication Year(JFY) : 2011
The nuclear power plant accident triggered by the Great East Japan Earthquake has drawn new attention to renewable energy. According to a study by the Ministry of the Environment, among the various types of renewable energy, wind power has the highest introduction potential by far with an installed capacity of 1.9 billion kW. However, introduction would require legal acts, supporting projects, and technological innovation. At Kyushu University, a large-scale demonstration facility for a wind power system called the wind-lens turbine was completed at the Ito Campus. While providing power to the campus, tests to increase the scale of the system will be conducted. For the next stage, Professor Yuji Ohya, one of the developers of this system, plans to build an offshore wind farm in Hakata Bay to conduct field tests, and also has a concept to establish a Multi-source offshore energy farm on the Genkai Sea in the future.
Japan’s First XFEL Facility， SACLA， CompletedRunning Time : 5minutes Publication Year(JFY) : 2011
RIKEN and Japan Synchrotron Radiation Research Institute (JASRI) have completed Japan's first X-ray free electronic laser (XFEL) facility, named SACLA, which had been under construction at Harima Science Garden City since 2006. XFEL is said to be the “dream light,“ a completely new form of light for humankind. What kind of light is XFEL? What will it make possible? What distinguishes SACLA from competing XFEL facilities in the United States and Europe? These are the questions that are answered in this program.
