Advanced Technologies For Turbomachinery to Utilize Effectively Renewable Energies at Offshore

摘要: For the next leap in sustainable energy exploitations, we are under obligations not only to cope with warming global environment but also conserve natural ecosystems and coexist natures. This paper introduces following advanced technologies Kyushu Institute of Technology, utilize effectively promising ocean wind resources at offshore. (1) Counter‐Rotating Type Reversible Hydroelectric Unit, which is composed tandem runners peculiar generator double rotational armatures, applicable both rising falling tides power station embankment, place traditional bulb type turbines. (2) Gyro‐Type Hydraulic Turbine, some blades high aspect ratio, effective tide even shallow and/or very low range tide. (3) Submerged Ocean Wave Power where a pair floats lined up interval one wave pitch supports vertical hyd...
