3. Ocean Power – Piston Pump & Rack
Introduction
A most promising energy solution today is to harness the kinetic power of the Ocean waves and flowing currents of Sea or River.
Many projects are underway and they aim to generate enough electrical energy for millions of homes without burning fossil fuels.
These forces of nature are free, steady and predictable.

4. Ocean Power – Piston Pump & Rack
Concept
M/S IP Management Pte Ltd has invented a fluid currents energy converter device by combining double acting Piston Pump and moveable racks to convert Ocean waves or flowing currents into electricity.

6. Wave Power Reference - Wikipedia, the free encyclopedia
Waves are generated by wind passing over the surface of the sea.
As long as the waves propagate slower than the wind speed just above the waves, there is an energy transfer from the wind to the waves.

7. Wave Power Reference - Wikipedia, the free encyclopedia
Wave power formula
Example: Consider moderate ocean swells, in deep water, a few km off a coastline, with a wave height of 3 meters and a wave period of 8 seconds. Using the formula to solve for power, we obtain:
meaning there are 36 kilowatts of power potential per meter of wave crest.

8. WAVE ENERGY CONVERTER IN SHALLOW WATER
The maximum power capture of a floating buoy is given by (Matt Folley, et al, )
P = ½ F .. x (1- ½ r)
When the motion is highly constrained, r ---> 0, then the power capture is proportional to the incident wave force, not the incident wave power intensity given above. This is evident for shallow water converters where the water depth is less than a quarter of the wave wavelength.
where
F - is the wave force
X - is the amplitude of motion
r - is the ratio of amplitude of motion to optimum amplitude of motion

9. Power Capture of a Floating Buoy
The power capture of a floating buoy is also given by (Evans, )
where
 - is the applied hydrodynamic damping coefficient (in Ns/m)
 - is the angular velocity (in rad/s)
X - is the amplitude of motion (in m)
