Purpose, Objectives, & Integration
The Challenge:A renewable energy source that is persistent and consistent, with low operating
cost, low environmental impact and rapid commercialization.
This promotes the Program by:
Producing continuous power from wave energy Providing a model product demonstrating a successful renewable
Developing methods for rapidly commercializing new power technology
Having a cost-effective system to replace or augment legacy systems
Our Objective: develop & validate a generation system that Harvests energy from shoreline waves especially if they are destructive
Can be brought to market quickly
Can be integrated with grids, legacy systems, renewable sources andstorage facilities or used in isolation
Works in variety of conditions & has a low energy cost when mass produced

Technical Approach & Issues
Our solution: a modular approach Many small repeating modules = lower manufacturing costs
Not just one unit = mitigated points of failure
Can be arranged in configurable sets and arrays = customize to site conditions
Plug and play components = rapid changeover for maintenance, expansion or upgrade
Maintenance by module swap-out = shutdown of entire system not required
Designed for near-shore installations or man-made structures
Potential installation siting and permitting obstacles reduced
Can be used to reduce wave impact on structures
Lower costs of installation, operation and maintenance since not in deep open water
Solar Panel analogy: direct feed to local loads or combined for utilities
Issues: Survivability
How to reduce Cost of Energy
Improve manufacturing techniques, materials and processes

Unique Features & Accomplishments
Unique because: Fast to market - first prototype at full scale
Wide market - applicable to both small and large installations
Organic-growth business model - steady, secure growth of experience & finance
Accomplishments
Invented a new generator design Dramatic cost reduction to current design Potentially more effective in converting energy to electricity
Amended the initial design: Harvest both heave & surge More robust and survivable for marine environments
Built and tested three generator iterations Improved initial design to quadruple output Lab tests extrapolated to known water conditions: 200-400 watts
Redesigned manufacturing process Exploring significant cost-savings
On budget on target
