A radically different approach to harvesting wave power is by compressing water inside a rubber tube.
Technology:
- Wave damper
- During the high pressure part of the cycle, water passes through a set of non-return valves into an accumulator where pressure is allowed to build up.
- A smoothed flow of water then passes from the accumulator into a conventional hydraulic turbine which drives an electrical generator.
- On exit from the turbine, the water is accepted into a low pressure accumulator and is then drawn through another set of non-return valves back into the main tube during the low pressure part of the bulge wave cycle.
Advantages:
- Floating device: easy to install, transport, maintain etc
- Light weight rubber structure
- Survivability, no "hard-limits"
- Few parts, low maintenance
Disadvantages:
- How much of the available energy is it able to capture?
Cost:
- Unknown
