A power take off solution to convert the forces from ocean wave motion to usable electricity Magnetohydrodynamic (MHD) Ocean Wave Energy Conversion System (MWEC) SARA’S PATENTED MWEC POWER TAKE OFF SYSTEM IMPROVES EFFICIENCY, MOBILITY, SIMPLICITY, AND RELIABILITY OF OCEAN WAVE ENERGY CONVERSION SYSTEMS.. A MHD generator at Heave-based System the heart of a MAIN FEATURES: Concept Elements MWEC device. Highly compatible with heave-based systems Efficient, high power density, low capital cost generator (MHD) Does not employ a conventional rotating electric generator Upp Shifts the impedance-matching burden from the mechanical to the electrical domain er o il ch MHD output (very high current, low voltage) can be converted to more practical levels 16 am MH ber via efficient electronic switches and compact transformers. link Dc ed ells Efficient, compact, economical, and deployable. in s erie s HOW DOES IT WORK? Electrical Couples to up/down motion of heave based systems Low outputs to up- A shaft transfers wave motion to the MHD generator which is deep underwater er o il c converter (no wave motion) ham The shaft forces the conducting fluid through powerful permanent magnets ber Low voltage/high current electrical energy is generated via the MHD interaction An electrical inverter converts the electrical energy to commercial quality 60 Hz AC power Power is transmitted to shore from multiple generating stations and connected to the grid MHD Demonstrated ~50% Efficiency in Converting Mechanical Power to Electricity Across the Entire Range Tested. That’s far better than alterna- tive power take off devices! MWEC Applications Offshore farms of MWEC systems using SARA’s MHD powering the onshore grid can provide megawatts of electricity Reliable deep-ocean power-generation systems for remote Unique MHD Cell Design sub-sea wellheads US Patent #7,166,927 Rapidly deployable, cost-effective MWEC systems for military applications such as unmanned underwater vehicle docking stations or temporary power for remote sites MWEC Advantages It is highly efficient at converting ocean wave energy to electricity 24/7, 365 days per year It is compact, reliable, efficient and rapidly/easily deployable It has no gears, levers, turbines, drive belts, bearings, transmission, etc. 6300 Gateway Drive Capital needs and maintenance costs are low. Cypress, CA 90630-4844 It is highly-compatible with all ocean wave heights.
