Wavebob was a wave energy converter which was in development between 1999 and 2013. It commenced the first of a number of sea trials in Galway Bay in Ireland during which it was tested its a 1/4 scale device for short periods at the SEAI 1/4 Scale Wave Power Testing facility〔(Description of Galway Bay Wave Test Facility from SEI Website )〕 which is located in the inner bay inside the natural Aran Islands breakwater and where devices under test are exposed to c.1/3 of the expected energy of the 'Full Atlantic Ocean'.〔(Ireland Wave Atlas Online GIS . SEI Quarter Scale Test Site Located At -9.269W 53.233N )〕〔(Ireland Wave Atlas Online GIS . SEI Full Scale Model Test Site To Be Constructed and Located At -9.989W 54.164N ) Coming Onstream 2011 or 2012〕 ==Technology== Wavebob used the lift and fall of ocean waves to drive generators A broad consensus, but not a universal one, accepts the following as established in the Wave Energy Industry: # The best energy resource is offshore, i.e. in water depths greater than half a wavelength # Oscillating systems represent an effective way of absorbing wave energy〔^ a b McCormick, Michael E., and R. Cengiz Ertekin. Mechanical Engineering-CIME 131.5 (2009): 36. Expanded Academic ASAP. Web. 5 October 2009.〕 #Ocean swell is preferable to local wind-waves # A self-reacting device will be preferred to one that reacts against the sea-bed # Floating/surface-piercing devices are preferable to totally submerged devices # Survivability and tunability (ability to cope with different wave climates) are key design requirements # Wave Energy Converters will be deployed in large arrays, analogous to wind-farms The Wavebob consisted of two oscillating structures. These structures must be able to absorb in a variety of conditions and be robust to survive in the harsh marine environment. The structures are controlled by a damping system that can respond to predicted wave height, wave power and frequency. The tank structure (a semi-submerged body) uses captured sea water mass as the majority of its inertial mass. This significantly reduces the cost associated with structural materials. Wavebob developed its business through an Open Innovation Model and was partnered with leading energy companies such as Chevron and Vattenfall. It established a joint venture company with Vattenfall called Tonn Energy〔( Tonn Energy )〕 to develop commercial wave farms off the west coast of Ireland. 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「Wavebob」の詳細全文を読む スポンサード リンク
