  • Investigation and comparison of generators for dynamic operation in ocean buoys

    Creator:
    Schacher, Anthony Clinton
    Abstract:
    A significantly untapped renewable energy source exists in the world's oceans. It is estimated that if 0.2% of the ocean's untapped energy could be harnessed, it could provide power sufficient for the entire world. Ocean energy extraction is an old concept, and it is currently seeing the benefit of advancing...

  • Ocean electric energy extraction opportunities

    Creator:
    Zhang, Heng
    Abstract:
    The world's oceans contain tremendous renewable energy potentials. It is estimated that if 0.2% of the ocean's untapped energy could be harnessed, it could provide power sufficient for the entire world [1]. This thesis provides a comprehensive description of the state-of-the-art of ocean energy extraction technologies and lessons learned from...

  • A novel linear generator for wave energy applications

    Creator:
    Ernst, Steven George
    Abstract:
    With the increasing effort to identify alternative methods of energy generation, extraction of ocean energy has gathered a large interest. Research and industry have begun considering wave energy as the next new alternative energy. The unique challenges of ocean energy requires a wave energy converter to be both robust and...

  • Towards reliable and survivable ocean wave energy converters

    Creator:
    Brown, Adam C.
    Abstract:
    Ocean wave energy is a new and developing field of renewable energy with great potential. The energy contained in one meter of an average wave off the coast of Newport Oregon could supply dozens of homes with electricity. However, ocean waves are usually quite irregular which leads to large bursts...

  • A direct-drive wave energy converter with contactless force transmission system

    Creator:
    Agamloh, Emmanuel B.
    Abstract:
    Commonly proposed ocean wave energy converters (OWEC) use inefficient and maintenance demanding intermediate hydraulic and pneumatic systems. We propose a novel rotary direct-drive OWEC that eliminates these intermediate stages. The new device employs a contactless force transmission system (CFTS) comprising a “piston” and a “cylinder” and a ball screw to...

  • Novel design and implementation of a permanent magnet linear tubular generator for ocean wave energy conversion

    Creator:
    Prudell, Joseph H.
    Abstract:
    The world’s energy consumption is growing at an alarming rate and the need for renewable energy is apparent now more than ever. Estimates have shown that optimization of the extraction of energy from the ocean could significantly aid the world’s quest for sustainable and affordable energy services for all. From...

  • Evaluation of the performance of a taut-moored dual-body direct-drive waveenergy converter through numerical modeling and physical testing

    Creator:
    Elwood, David E.
    Abstract:
    With energy prices rising and increasing concern about the influence of fossil fuels on climate change, wave energy systems are on the verge of commercial implementation. These first generation wave energy converters utilize either pneumatics or hydraulics to convert the mechanical energy of waves into electricity. For the last several...

  • Numerical and assimilative studies of the equatorial Pacific cold tongue

    Creator:
    Perez, Renellys Christine
    Abstract:
    Numerical model and assimilation experiments were conducted in the tropical Pacific Ocean to obtain a better understanding of the processes that control the cold tongue surface mixed layer temperature balance during August 1999 to July 2004. The numerical model was first applied to test two hypotheses (asymmetric background currents and...

  • A linear test bed for characterizing the performance of ocean wave energy converters

    Creator:
    Hogan, Peter M.
    Abstract:
    Determining the performance characteristics of various ocean wave energy converters (OWEC) has proven to be difficult due to problems replicating a baseline motion profile in the ocean or wave tank to compare these devices. The linear test bed seeks to mechanically simulate the relative linear motion between the active components...

    Creator:
    Hunter, Daniel A.
    Abstract:
    Oregon’s coastal communities grew from the booming logging and fishing industries of the 19th century, but in recent decades have faced not only major declines in both timber and fish resources but also an increasing reliance on tourists and retirees and the resultant glut of seasonal service-sector jobs. As a...
