Core Technology: The Force Cancellation Concept

Wavepiston?s proprietary and patented technology is based on a modular, lightweight string system that functions just below the ocean's surface. Unlike "point absorber" buoys that bob up and down, the Wavepiston system utilizes horizontal wave motion.

Key Technological Features:

• Force Cancellation: The system consists of a long horizontal cable (string) anchored at both ends, with several vertical "energy collectors" mounted along it. Because the collectors are spaced out, they experience wave forces in opposing directions simultaneously. These opposing forces "cancel out," significantly reducing the load on the moorings and allowing for a much lighter, more cost-effective anchoring structure.
• Seawater Hydraulics: As waves pass, the energy collectors (underwater sails) move back and forth. This motion drives integrated hydraulic pumps that suck in and pressurize seawater.
• Low Visual Impact: Because the entire string is submerged, it is virtually invisible from the shore, making it an ideal solution for tourist destinations and coastal resorts.

Products and Services

1. Wave Energy Farms

Wavepiston provides turn-key wave energy installations designed to produce clean electricity. The pressurized seawater generated by the offshore strings is piped to a conversion station?either onshore or on an offshore platform?where it drives a standard hydropower turbine. * Scalability: A single string can be as long as 350 meters with up to 32 collectors. Multiple strings can be combined into large-scale "wave farms" capable of generating megawatts of power. * Intermittency Reduction: By co-locating with offshore wind farms, Wavepiston systems can share subsea cable infrastructure and provide a more stable power output, as wave energy often peaks at different times than wind energy.

2. Desalination Systems

One of Wavepiston's unique value propositions is the ability to produce freshwater directly from wave energy without an intermediate electrical step. * Direct Reverse Osmosis (RO): The high-pressure seawater generated by the collectors can be fed directly into a standard reverse osmosis system. This eliminates the energy losses associated with converting wave motion to electricity and back again for desalination. * Target Market: This is particularly valuable for small island developing states (SIDS) and remote coastal communities facing both energy and water scarcity.

3. Operation and Maintenance (O&M) Services

Wavepiston provides ongoing maintenance and spare parts for its installations. The system is intentionally "low-tech" in its offshore components?using standard mechanical parts and no active electronics in the water?to ensure that local personnel can perform most maintenance tasks using regular tugboats rather than specialized heavy-lift vessels.
