Azura is a wave power device currently being tested in Hawaii.〔(【引用サイトリンク】title=Innovative Wave Power Device Starts Producing Clean Power in Hawaii )〕〔(【引用サイトリンク】title=NWEI Deploys Azura Wave Energy Device in Hawai’i )〕 It is connected to the municipal grid providing electricity to Hawaii. According to the United States Department of Energy, this is the first time that a wave power generator has been officially verified to be supplying energy to a power grid in North America. This has been verified by the University of Hawaii.〔(【引用サイトリンク】title=Azura connects in Hawaii )〕 The device can generate 20 kilowatts of power.〔〔(【引用サイトリンク】title=Azura wave energy system deployed in Hawaii )〕 The device is at the Marine Corps Base Hawaii's Wave Energy Test Site (WETS) on the north shore of Kaneohe Bay, Oahu. It is situated on the surface of a 30-meter-deep berth where it is being monitored.〔 This prototype (TRL 5/6) was developed by Northwest Energy Innovations (NWEI) with the support of the U.S. Navy, the United States Department of Energy, and the University of Hawaii. It will be in operation for a 1-year period of assessment.〔〔 During that time, the University of Hawaii will be responsible for the collection and analysis of data.〔 Azura was originally named "WET-NZ" from "Wave Energy Technology-New Zealand". ==Description and operation== Azura floats on the surface of the sea and weighs 45 tons (41 tonnes). It has a unique floating mechanism that can rotate 360 degress. This enables it to extract power from horizontal (surge) as well as vertical (heave) wave motion.〔 It has reserve buoyancy that is very low, allowing it to partially submerge beneath large waves.〔(【引用サイトリンク】title=Ocean Energy - Azura wave energy device deployed at US Navy test site - Renewable Energy Magazine, at the heart of clean energy journalism )〕 Azura is a point absorber. This means that it uses a floating surface mechanism to absorb the energy of waves from different directions. This is the most common type of deepwater wave energy generator.〔(【引用サイトリンク】title=Wave Energy Developers Line Up for Hawaii Test Site )〕 The generator is driven with a high-pressure hydraulics system.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Azura (wave power device)」の詳細全文を読む スポンサード リンク
