One significant method for converting ocean wave energy into usable electricity involves deploying specific devices known as point absorbers.
Utilizing Point Absorbers
Point absorbers are a type of wave energy converter (WEC). Based on information from August 6, 2024, these are described as buoy-type systems designed to harvest incoming wave energy from all directions. They are typically positioned offshore, either floating on the ocean surface or situated just below it.
The Conversion Process
The core mechanism within a point absorber involves a crucial component: a vertically submerged floater. Here's how the conversion works according to the reference:
- Energy Absorption: The vertically submerged floater interacts with the waves, effectively absorbing their kinetic and potential energy.
- Conversion: The energy absorbed by the floater is then directly converted into electricity. This conversion is facilitated by a connected system, such as a piston or a linear generator.
This process allows the up-and-down or orbital motion of the waves to drive a generator, producing electrical power.
