The Oscillating Device is designed to convert the energy of sea waves into usable energy e.g. electricity.

The machine consists of the following main components:

- annual shaped floater

- floating column

- universal joint mechanism

- water chambers (filled with sea water)

- mechanical or pneumatic springs

- air pumps

- electrical generator

The floater is coupled to the column by means of the universal joint mechanism. The water chambers is connected to the lower end of the column. The air pumps are mounted between the floater and column and between the column and water chambers.  

In response to sea wave forces the floater and column oscillate vertically and about horizontal axes while the water chambers oscillate vertically. The air pumps transfer energy to the electrical generator by damping the relative motion between the floater, column and water chambers.

Features:

• High efficiency as the machine is able to capture energy from vertical, pivotal and horizontal motion
• Easy to deploy and operate
• Operative in any wave direction

Oscillating Device

A device oscillating in both vertical and horizontal direction can in theory absorb 100% of the wave force acting on the device. To read more about the principles of wave energy absorptium click here
