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 and storage

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
