Summary on Grant Application Form
Many wave power inventors begin with floats that move vertically. However previous work at Edinburgh University showed that a movement along a fixed slope angle constrained by a guide way gives much better hydrodynamic performance because of reduced hydrodynamic spring rate and better wave-making capability. The resonant period can be tuned by changing the slope angle but the bandwidth is so wide that a 45-degree slope fill cover all the Atlantic spectra.The slope idea can be combined with the stroke-limiting scheme developed by the Swedish IPS company with force reaction obtained from a water piston coupled to an internal water mass.The project will develop a linear eddy-current dynamometer that can be used with other free-floating models and will establish the best shape and dimensions for buoy heads and slope plates.All the data needed for full-scale design and cost elimination will be collected and tabulated.
